Improper certificate validation in Apereo CAS Client 4.1.0 and Jasig CAS Client 3.6.4 allows a man-in-the-middle attacker to intercept Ticket-Granting Tickets (TGTs) by presenting any CA-signed certificate for a hostname matching the client's allowlist. An attacker with a network interception position can then obtain service tickets on behalf of the victim. No active exploitation or public exploit code is confirmed, and EPSS indicates low exploitation probability (0.17%).
Authentication bypass in Eclipse Jetty's HTTP Digest authentication implementation allows an unauthenticated attacker who knows a target username to authenticate as any user whose password contains non-Latin-1 characters (CJK, Cyrillic, Arabic, Greek, emoji, etc.) by substituting those characters with literal '?' characters. The root defect is in DigestAuthentication.java, which uses ISO-8859-1 encoding at three points when computing H(A1), H(A2), and the final MD5 response hash - silently collapsing all code points above U+00FF to 0x3F, making collision credentials cryptographically indistinguishable from the original. A publicly available proof-of-concept demonstrates hash collision across Chinese, Korean, Cyrillic, and Greek passwords; no active exploitation has been confirmed by CISA KEV at time of analysis.
Takeover of Oracle Platform Security for Java (OPSS) is possible where a low-privileged attacker with HTTP network access can fully compromise the confidentiality, integrity, and availability of the service. The flaw resides in the Centralized Thirdparty Jars component and affects Oracle Fusion Middleware releases 12.2.1.4.0 and 14.1.2.0.0. It carries a CVSS 3.1 base score of 8.8 and was disclosed in the Oracle Critical Patch Update of July 2026; no public exploit identified at time of analysis.
Full compromise of Oracle Platform Security for Java (OPSS) in Oracle Fusion Middleware 12.2.1.4.0 and 14.1.2.0.0 is possible by a low-privileged attacker over HTTP, targeting the Centralized Thirdparty Jars component. Oracle rates the flaw 8.8 and describes it as 'easily exploitable,' with successful attacks yielding complete takeover (high confidentiality, integrity, and availability impact). No public exploit is identified at time of analysis and the CVE is not listed in CISA KEV.
Full compromise of Oracle Platform Security for Java (OPSS) in Oracle Fusion Middleware versions 12.2.1.4.0 and 14.1.2.0.0 allows a low-privileged attacker with network access over HTTP to take over the component, per Oracle's July 2026 Critical Patch Update. The flaw yields high confidentiality, integrity, and availability impact and is rated easily exploitable (CVSS 8.8), though no public exploit identified at time of analysis. Because OPSS underpins authentication, authorization, and credential management for the wider Fusion Middleware stack, a takeover has cascading security consequences.
Full compromise of Oracle Platform Security for Java (OPSS), a security framework within Oracle Fusion Middleware, is possible when a low-privileged attacker reaches the affected instance over HTTP via the Centralized Thirdparty Jars component. Oracle rates the flaw CVSS 3.1 8.8 and describes it as "easily exploitable," resulting in a complete takeover of OPSS with high confidentiality, integrity, and availability impact. No public exploit identified at time of analysis and it is not in CISA KEV, but the low attack complexity and only a low-privilege authenticated prerequisite make it a strong candidate for prompt patching in Oracle environments.
Full compromise ("takeover") of Oracle Platform Security for Java (OPSS), a core security framework shipped inside Oracle Fusion Middleware, is possible by an unauthenticated remote attacker over HTTP against versions 12.2.1.4.0 and 14.1.2.0.0. Oracle rates this 9.8 with full confidentiality, integrity, and availability loss and describes it as "easily exploitable," so it should be treated as a top-priority patch in the July 2026 Critical Patch Update. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the trivial exploitation profile (no authentication, no user interaction) makes it an attractive target once details or patches are reverse-engineered.
Full takeover of Oracle Platform Security for Java (OPSS), a security framework within Oracle Fusion Middleware, is possible for a low-privileged attacker positioned on the same physical communication segment as the host. Disclosed in Oracle's July 2026 Critical Patch Update, the flaw carries a CVSS 3.1 score of 8.0 and a scope change, meaning successful exploitation can significantly impact additional products beyond OPSS itself. Exploitation is rated difficult (AC:H) and there is no public exploit identified at time of analysis, so risk is elevated by potential blast radius rather than by ease of attack.
Full takeover of Oracle Platform Security for Java (OPSS), a security framework bundled with Oracle Fusion Middleware 12.2.1.4.0 and 14.1.2.0.0, is possible via its Centralized Thirdparty Jars component. A low-privileged attacker with HTTP network access can compromise confidentiality, integrity, and availability, though the attack is rated difficult to execute (high attack complexity). No public exploit identified at time of analysis and the flaw is not in CISA KEV, but it was disclosed by Oracle in the July 2026 Critical Patch Update.
Full compromise of Oracle Platform Security for Java (OPSS) in Oracle Fusion Middleware versions 12.2.1.4.0 and 14.1.2.0.0 is achievable by a low-privileged attacker over HTTP through the Centralized Thirdparty Jars component. Because the flaw carries a scope change, successful exploitation can result in complete takeover of OPSS and significantly impact additional connected products, earning a near-maximum CVSS 3.1 base score of 9.9. No public exploit has been identified at time of analysis, but the low attack complexity and minimal privilege requirement make this a high-priority patch.
Full takeover of Oracle Platform Security for Java (OPSS) is possible in Fusion Middleware versions 12.2.1.4.0 and 14.1.2.0.0, where a low-privileged attacker with network access can compromise the component via crafted SOAP requests. Oracle rates this CVSS 8.8 with high confidentiality, integrity, and availability impact, meaning successful exploitation yields complete control of the OPSS component rather than mere data exposure. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Remote takeover of Oracle Platform Security for Java (OPSS), a security framework bundled with Oracle Fusion Middleware versions 12.2.1.4.0 and 14.1.2.0.0, allows an unauthenticated attacker with HTTP network access to fully compromise the component. Rated CVSS 3.1 9.8 with high confidentiality, integrity, and availability impact, Oracle describes it as 'easily exploitable' via the Centralized Thirdparty Jars component. No public exploit has been identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and lack of authentication make it a high-priority patch.
Complete takeover of Oracle Platform Security for Java (OPSS) in Oracle Fusion Middleware 12.2.1.4.0 and 14.1.2.0.0 is possible by an unauthenticated remote attacker over HTTP, per Oracle's July 2026 Critical Patch Update. The flaw resides in the 'Centralized Thirdparty Jars' component and carries a maximum CVSS 3.1 base score of 10.0 with a scope change, meaning successful exploitation can significantly impact products beyond OPSS itself. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the perfect CVSS score and 'easily exploitable' vendor language make this a top-priority patch.
TLS certificate-revocation bypass in Netty's OcspServerCertificateValidator (netty-handler-ssl-ocsp, versions <4.1.136.Final and 4.2.0.Final-4.2.16.Final) allows a malicious server presenting a revoked certificate to receive sensitive client data during a race window. The validator forwards the SslHandshakeCompletionEvent to downstream handlers before the asynchronous OCSP check finishes, so client applications treat the connection as trusted and may transmit or process application data before the revoked channel is closed. Publicly available exploit code exists (PoC in the GHSA advisory); no public active exploitation has been reported and the vulnerability is not in CISA KEV.
Certificate revocation bypass in the Netty netty-handler-ssl-ocsp module (versions before 4.1.136.Final, and 4.2.0.Final through 4.2.15.Final) lets an on-path attacker replay a stale, expired-but-GOOD OCSP response to make OcspServerCertificateValidator accept a certificate that has since been revoked. A missing return statement after the freshness check causes execution to fall through and still fire a VALID OcspValidationEvent even after flagging the response as out-of-date. Publicly available exploit code exists (a PoC unit test is embedded in the GHSA advisory); the issue is not listed in CISA KEV and no EPSS score was provided.
Local privilege escalation to full takeover in the Install component of Oracle Java SE (8u491, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1), Oracle GraalVM for JDK (17.0.19, 21.0.11), and Oracle GraalVM Enterprise Edition (21.3.18) lets a low-privileged local user compromise the runtime and take it over with full confidentiality, integrity, and availability loss. Oracle rates it 7.8 (High) and describes it as easily exploitable by an attacker holding only a logon to the host. No public exploit has been identified at time of analysis and it is not on CISA KEV.
Unauthorized data modification in Oracle Java SE, GraalVM for JDK, and GraalVM Enterprise Edition (Libraries component) lets a remote, unauthenticated attacker corrupt, create, or delete critical data by feeding crafted input to affected Java APIs, for example through a web service that passes data to those APIs. It carries CVSS 3.1 7.5 with an integrity-only impact (C:N/I:H/A:N) and is described by Oracle as easily exploitable over multiple network protocols. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the ubiquity of the Java runtime makes patching a priority.
Unauthorized data access and modification in the Scripting component of Oracle Java SE 8u491, 8u491-perf, and 11.0.31 allows a remote unauthenticated attacker to compromise the confidentiality and integrity of all Java-accessible data via APIs reachable over multiple network protocols. Rated CVSS 3.1 7.4 (High) by Oracle, the flaw is difficult to exploit (AC:H) and carries no availability impact; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. It also affects sandboxed Java Web Start/applet deployments that run untrusted code and rely on the Java sandbox.
Denial-of-service in Oracle Java SE 8u491 (and 8u491-perf) and 11.0.31 lets an unauthenticated remote attacker hang or repeatedly crash the JVM by feeding crafted input to the Scripting component's APIs, for example via a web service that passes data to those APIs. There is no confidentiality or integrity impact - only availability - but the attack is network-reachable, low-complexity, and requires no authentication or user interaction, yielding a CVSS 7.5. No public exploit identified at time of analysis and the flaw is not on CISA KEV.
Remote denial of service in the Netty networking framework (codec-haproxy module) versions 4.1.0.Final through 4.1.135 and 4.2.0.Final through 4.2.15.Final lets unauthenticated attackers exhaust JVM direct memory. The HAProxyMessageDecoder mis-parses a PROXY protocol v2 header whose version byte is 0xFF, sign-extending it to -1, which collides with the decoder's 'need more data' sentinel, so ByteToMessageDecoder accumulates inbound bytes in an unbounded cumulation buffer until the process runs out of direct memory. No public exploit identified at time of analysis; the CVSS 4.0 score of 8.7 reflects high availability impact with no confidentiality or integrity effect.
Remote code execution risk in Apache Fory (the Java serialization framework formerly known as Fury) before 1.4.0 arises because attacker-supplied data can bypass the class-registration allowlist during Java lambda deserialization, with the gap confined to the lambda capture class. Registration checks are Fory's core defense against untrusted-deserialization gadget attacks, so bypassing them for lambda payloads can let an attacker instantiate otherwise-disallowed classes and reach code execution or memory corruption. There is no public exploit identified at time of analysis and this CVE is not listed in CISA KEV; the vendor (Apache) rates it CVSS 9.8 and a fixed release (1.4.0) is available.
SQL injection in AiFlowy versions 2.1.2 and earlier lets remote attackers extract sensitive database contents through the getPageData method in DatacenterQuery.java. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) indicates unauthenticated, low-complexity network exploitation with high confidentiality impact but no integrity or availability effect. A public technical write-up with reproduction details exists on GitHub, though the low EPSS score (0.19%, 8th percentile) and absence from CISA KEV indicate no confirmed active exploitation at time of analysis.
Information disclosure in aiflowy (an open-source Java/Spring-based AI workflow / low-code platform) versions 2.1.2 and earlier lets remote unauthenticated attackers extract sensitive information through the JobUtil.java scheduling component. The public technical writeup titled 'Any SpringBean invocation' indicates the flaw stems from unrestricted invocation of arbitrary Spring beans, which can be abused to read internal application state and secrets. No CISA KEV listing and a low EPSS score (0.19%, 9th percentile) suggest no observed mass exploitation, but a public technical analysis describing the technique exists.
Path traversal in Apache MINA SSHD's sshd-git component lets an authenticated remote user on Windows-hosted git servers escape the configured server-side root directory and reach git repositories elsewhere on the filesystem. It is an incomplete-fix regression of CVE-2026-48827: the path validation added in 2.18.0 and 3.0.0-M4 was only partly effective on Windows path semantics. No public exploit identified at time of analysis; not listed in CISA KEV, and no EPSS score was provided.
Command-restriction bypass in Apache MINA SSHD (server-side) lets a user who authenticates with an OpenSSH user certificate carrying a force-command directive execute arbitrary commands instead of the single restricted command the certificate authority intended. The server accepts and honors such certificates but silently ignores the force-command and verify-required options, breaking the security model that certificate issuers rely on to constrain principals. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the flaw is confirmed and fixed by the Apache Software Foundation in versions 2.19.0 and 3.0.0-M5.
Arbitrary file write in Apache MINA SSHD's sshd-scp component lets a malicious SCP sender place files outside the intended download directory because filenames in SCP 'C' (file) and 'D' (directory) commands are not validated for path separators. Any application acting as an SCP receiver - either an SSHD server accepting uploads or an SCP client fetching from a server - using unsupported versions <2.0.0 or the sshd-scp module in >=2.0.0 is affected, allowing an attacker to overwrite or plant files in attacker-chosen locations. Reported by Apache; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Privilege escalation in Apache Syncope's identity-management engine lets a self-service user grant themselves defined Roles via a single REST API call, effectively promoting a low-privileged or newly self-registered account to administrator. It affects deployments running the all-Java user workflow adapter, or the Flowable adapter with a BPMN definition that does not require admin approval for self-registration or self-update, across versions 3.0.0-M0-3.0.16, 4.0.0-M0-4.0.6, and 4.1.0-M0-4.1.1. The Apache-issued advisory rates it CVSS 9.8; no public exploit identified at time of analysis and it is not on CISA KEV.
Unauthenticated remote denial of service in the JLine3 remote-telnet server module (versions before 3.30.14, 4.0.16, and 4.2.1) lets an attacker crash the JVM by flooding the Telnet NEW-ENVIRON negotiation with unbounded unique environment-variable pairs. Because TelnetIO.readNEVariables() stores every pair in an uncapped HashMap on ConnectionData before login, roughly 3-4 MB of traffic can exhaust a 512 MB heap and force an OutOfMemoryError. No public exploit code is identified, but the vendor advisory (GHSA-47qp-hqvx-6r3f) documents proof-of-concept methodology; the flaw is not listed in CISA KEV and no EPSS score was supplied.
Denial of service in the JLine3 Telnet server (jline-remote-telnet module) lets an unauthenticated remote attacker exhaust server CPU by abusing the Telnet NAWS window-size option. Because TelnetIO enforces only a lower bound on terminal dimensions, a client can advertise a 65535x65535 terminal and repeatedly alternate values to force continuous, expensive redisplay/rendering cycles. Publicly available exploit code exists (a raw two-packet Telnet PoC is published in the vendor GHSA advisory), and there is no public exploit identified as being actively exploited; the issue is fixed in 3.30.14, 4.0.16, and 4.2.1.
SQL injection in cool-admin-java 8.0.0 lets attackers inject arbitrary SQL through the order() method of CrudOption.java, a shared CRUD helper used across the framework's auto-generated data endpoints. The flaw carries an NVD CVSS of 9.8 (CWE-89) and, if reachable without authentication as the vector implies, permits full read/write access to the backing database. There is no public exploit identified at time of analysis and EPSS is low (0.14%, 4th percentile), indicating minimal observed exploitation activity so far.
Missing-authorization schema tampering in ArcadeDB before 26.6.1 lets any authenticated identity - including a read-only API token that lacks the UPDATE_SCHEMA permission - mutate the database schema over the HTTP command/query endpoints. Because CVE-2026-44221's fix only added the UPDATE_SCHEMA check to LocalDocumentType.createProperty, the remaining schema mutators (DROP PROPERTY, ALTER TYPE, ALTER PROPERTY, type/bucket/alias changes) stayed unguarded, so a low-privilege user can drop properties, rename or re-parent types, and flip property constraints, corrupting the meaning of every stored record. There is no public exploit identified at time of analysis and it is not in CISA KEV, but the vendor advisory (GHSA-vg6x-6pg9-6qwg) confirms the flaw and a fix in 26.6.1.
Server-Side Request Forgery and arbitrary local file read in ArcadeDB before 26.6.1 let any authenticated user with SQL command/query access - not just root/administrators - abuse the SQL `IMPORT DATABASE` statement, whose source URL was passed to the importer unchecked. Because it required no administrative privileges, a low-privileged user could force the server to fetch arbitrary HTTP(S) endpoints (including cloud metadata at 169.254.169.254 and internal-only services) and ingest the responses as queryable records, or read local files such as `/etc/passwd` and credential files via `file://` paths. No public exploit identified at time of analysis; the flaw was privately reported and fixed in release 26.6.1.
Build-time remote code execution in Nuclio (serverless/FaaS platform) versions <= 1.15.27 lets remote attackers run arbitrary OS commands as root inside the function-builder container. The Java runtime renders user-supplied runtimeAttributes.repositories values into a Groovy build.gradle file via Go's text/template using the non-escaping {{ . }} action, so an attacker can inject a closing brace to break out of the repositories {} block and append Groovy that Gradle executes during its configuration phase. Because the Dashboard API defaults to NOP (no) authentication, exploitation needs no credentials; a dynamically-verified proof-of-concept is published in the vendor advisory, though there is no public exploit identified as being used in active attacks.
Authentication/access-control bypass in BigBlueButton's bbb-web component (versions prior to 3.0.21) lets remote attackers reach protected API endpoints without a valid checksum by supplying the presentationUploadExternalUrl parameter. BigBlueButton's API is normally guarded by a shared-secret checksum, so bypassing it undermines the core authorization mechanism for calls such as CreateMeeting. No public exploit identified at time of analysis, though the fixing commit is public; CVSS is 8.1 and there is no CISA KEV listing or EPSS signal in the provided data.
Session hijacking in BigBlueButton before 3.0.21 lets an authenticated conference participant predict and reuse other users' session tokens to impersonate them. The bbb-web component generated 16-character sessionToken values (and 12-character auth tokens and internal user IDs) using Apache Commons RandomStringUtils.randomAlphanumeric, a non-cryptographic PRNG, making the token space guessable to anyone who already holds a valid session. Rated CVSS 8.1 with high confidentiality and integrity impact; no public exploit identified at time of analysis.
Authentication bypass in VMware/Spring's Spring Authorization Server (versions 7.0.0-7.0.4, 1.5.0-1.5.6, 1.4.0-1.4.9, and 1.3.0-1.3.10) allows a low-privileged authenticated actor to circumvent authentication controls and access protected resources across a security boundary. The CVSS 9.6 (Critical) rating reflects a scope change with high confidentiality and integrity impact but no availability effect. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the near-maximum score in a widely deployed OAuth2/OIDC authorization component makes this a high-priority patch.
Remote authenticated code execution in DataEase before 2.10.23 lets a low-privileged user abuse the Excel/datasource upload workflow to run arbitrary Java. By uploading a crafted payload.zip via /datasource/upload and defining an H2 datasource that references the archive through the zip: protocol, an attacker forces CalciteProvider.jdbcFetchResultField to execute a query that triggers precompiled Java aliases embedded in test.mv.db. The vendor CVSS 4.0 vector scores this 7.1 (confidentiality-only), but the underlying primitive is full arbitrary code execution; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Arbitrary file write leading to code execution in jadx 1.5.2 through 1.5.5 allows a malicious .xapk sample to escape the XAPK plugin unpack directory and plant a JAR under plugins/dropins, which the next jadx launch loads and executes via URLClassLoader/ServiceLoader. The flaw stems from XApkLoader calling tmpDir.resolve(fileName) after a flawed CWD-based ZIP name check, giving an analyst opening a crafted file a path traversal that escalates to attacker-controlled plugin code. Publicly available exploit code exists (SSVC exploitation: poc) but it is not in CISA KEV, and EPSS is very low at 0.13% (3rd percentile), consistent with a local, user-interaction-gated, high-complexity issue rather than mass exploitation.
Arbitrary Groovy code execution in the jadx Dex-to-Java decompiler (prior to 1.5.6) allows a malicious APK to run attacker-controlled code on the analyst's machine. When jadx exports a decompiled APK as an Android Gradle project, it copies the android:versionName value from AndroidManifest.xml into the generated build.gradle Groovy template without sanitization, letting a crafted value break out of the string literal and inject code that executes when the victim opens or builds the exported project. No public exploit identified at time of analysis; EPSS risk is low (0.15%, 5th percentile) and CISA SSVC records exploitation as none, but the technical impact is total.
Denial of service in the Netty netty-codec-stomp module (versions 4.1.x up to 4.1.135.Final and 4.2.0.Alpha1 through 4.2.15.Final) allows a remote attacker to trigger an OutOfMemoryError and crash the JVM. The StompSubframeDecoder caps individual header line length via maxLineLength but never bounds the total header count or cumulative header size, so a single STOMP frame packed with thousands of short headers exhausts heap memory. Publicly available exploit code exists (a working client/server PoC is published in the GitHub Security Advisory), but there is no public evidence of active exploitation; EPSS/KEV signals are not present in the input.
Privilege elevation in Microsoft Azure Spring Apps allows an already-authenticated, low-privileged network attacker to gain higher privileges by abusing an improper authentication weakness (CWE-287) in the managed platform. Because the CVSS scope is marked as changed (S:C), a successful attack can reach resources beyond the attacker's originally authorized boundary, yielding high confidentiality and integrity impact. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV; Microsoft has published an advisory and a patch is available server-side.
Unauthenticated arbitrary file write in Eclipse BaSyx Java Server SDK (2.0.0-milestone-05 through 2.0.0-milestone-12) lets remote attackers plant files anywhere the Java process can write when the server is deployed with the MongoDB file backend, potentially escalating to remote code execution. The AAS thumbnail API trusts a client-supplied fileName that is later reused as a filesystem path, so a traversal or absolute-path filename lands attacker-controlled bytes outside the intended directory. There is no public exploit identified at time of analysis and the issue is not in CISA KEV, but the vendor-fixed release (2.0.0-milestone-13) is available.
Reflected cross-site scripting in SAP NetWeaver Application Server Java (specifically the Configuration Wizard component) lets an unauthenticated attacker embed malicious JavaScript in crafted URLs that executes in a victim's browser when the link is opened. Because the CVSS scope is changed (S:C) and confidentiality impact is high, a successful lure can expose sensitive session information and tamper with non-sensitive data rendered in the client. No public exploit identified at time of analysis, but the 8.2 CVSS and unauthenticated, network-reachable vector make it a meaningful phishing-driven risk for exposed SAP portals.
Server-side request forgery in codecentric Spring Boot Admin Server before 4.1.2 lets unauthenticated remote attackers register a monitored instance with attacker-controlled healthUrl and managementUrl values that are never validated against private IP ranges or cloud metadata endpoints. Because the server then fetches those URLs and exposes the response bodies through its actuator proxy, an attacker can pivot into internal networks and read back sensitive data such as cloud instance-metadata credentials. Publicly available exploit code exists and the flaw was reported by VulnCheck, though there is no public exploit identified as actively exploited (not in CISA KEV).
Incorrect equality comparison in CedarJava (cedar-java) versions before 4.9.0 causes EntityIdentifier.equals() to return true when comparing against null and false when comparing an object to itself, due to inverted null/self-reference branches. Cedar's actual authorization decisions are unaffected because they are computed in Rust from JSON, but integrators who call equals() on entity identifiers in their own Java logic may make incorrect trust or access decisions. No public exploit identified at time of analysis; the issue is fixed in 4.9.0.
Remote code execution in Mura CMS versions prior to 10.0.712 allows unauthenticated attackers to execute arbitrary CFML and instantiate malicious Java objects by abusing the unvalidated 'method' parameter in POST requests to the /index.cfm/_api/json/v1/default JSON API endpoint. Because the ColdFusion engine processes the attacker-controlled input without sanitisation, a single crafted request yields full compromise (VC:H/VI:H/VA:H). No public exploit identified at time of analysis, though CISA SSVC flags the flaw as automatable with total technical impact.
Unsafe reflection in Apache IoTDB's pipe processor lets a user-supplied fully qualified Java class name be loaded and instantiated via Class.forName().newInstance() with no allowlisting, enabling arbitrary class loading and likely remote code execution in the database server process. It affects all releases from 1.0.0 up to (but not including) 2.0.10 and is fixed in 2.0.10. No public exploit identified at time of analysis, and EPSS is low (0.25%, 17th percentile), though CISA SSVC rates the technical impact as total and considers exploitation automatable.
Remote code execution in Metabase's H2 database driver allows an authenticated user with native-query privileges to run arbitrary Java on the server. When Metabase returns H2 result columns of type OTHER (JDBC JAVA_OBJECT), it deserializes the embedded Java object without validation, so a crafted native H2 query triggers CWE-502 unsafe deserialization and full server compromise. It affects any instance using an H2 connection, including the default bundled sample database. No public exploit is identified at time of analysis (SSVC exploitation: none; EPSS 0.45%), though the upstream fix commit and vendor advisory GHSA-w95f-x9v9-wv36 are public.
Remote code execution in Metabase (open-source BI/analytics platform) versions 1.55.0 through the fixed releases arises because one database-creation code path failed to validate unsafe H2 JDBC connection properties, letting an authenticated administrator register a crafted H2 datasource and run arbitrary Java on the server host. Because the CVSS scope is Changed (S:C), successful exploitation escapes the application context and yields full host compromise. No public exploit has been identified at time of analysis and it is not listed in CISA KEV, but the CVSS base score of 9.1 and RCE nature make it a high-priority patch for any exposed Metabase instance.
Remote code execution in DSpace 8.0-8.3 and 9.0-9.2 allows an authenticated administrator to execute arbitrary Java via Velocity templates used to render COAR Notify/LDN messages, using reflection to escape the templating sandbox. Exploitation requires valid DSpace administrator credentials and is most impactful when chained with the related LDN path-traversal flaw (GHSA-9qm4-rh6w-pq5x). No public exploit identified at time of analysis, and CVSS is 8.0 (High).
Remote code execution in Apache Gravitino before 1.2.1 allows unauthenticated callers to abuse the testConnection API by submitting a crafted H2 JDBC URL whose INIT parameter runs arbitrary Java on the server. The flaw only manifests when Gravitino is backed by the H2 database - a configuration primarily used for testing and local development - and CISA SSVC rates technical impact as total and exploitation as automatable, though no public exploit has surfaced. Fixed in 1.2.1; because Gravitino is usually deployed on internal networks and H2 is not the production default, the vendor characterizes real-world severity as low despite the 9.1 CVSS score.
Sensitive information disclosure in OneBlog V2.3.9 lets remote unauthenticated attackers retrieve WeChat Official Account secrets - the access_token and jsapi_ticket - through unprotected REST endpoints backed by RestApiController.java, JsApiTicketComponent.java, and GetAccessTokenComponent.java. Because these credentials grant control over the linked WeChat public account, disclosure enables account takeover of the integration rather than just data leakage. Classified CWE-306 (Missing Authentication); a referenced public gist appears to contain proof-of-concept details, though EPSS is low (0.26%, 18th percentile) and it is not listed in CISA KEV.
Arbitrary file read in OpenRemote's KNXProtocol asset-import handler lets any authenticated user (PR:L, any realm) upload a malicious ETS project ZIP whose 0.xml is parsed via Saxon XSLT and XMLInputFactory without XXE hardening, resolving external entities to exfiltrate server files such as /etc/passwd, openmrs-runtime.properties, and cloud credential files, with SSRF against internal endpoints as a secondary impact. This is an incomplete-fix regression of CVE-2026-40882, which only hardened the parallel Velbus handler and left KNXProtocol's two XML parsing calls unprotected. A full working proof-of-concept reproducing both parsing stages is publicly available; the vulnerability is not listed in CISA KEV.
Cross-tenant information disclosure in OpenRemote Manager lets a realm admin of one tenant read the profile, realm roles, and client roles of any user in any other realm - including the privileged master realm - simply by supplying the target user's UUID in the REST API path. Three read endpoints in UserResourceImpl verify the caller's read:admin role but never confirm the target user belongs to the caller's realm, breaking multi-tenant isolation for user data. Publicly available exploit code exists (a working curl-based PoC with live-instance HTTP 200 responses is documented), though it is not listed in CISA KEV and no active exploitation is confirmed.
Untrusted Java deserialization in Apache OpenNLP's SvmDoccatModel (libsvm document categorization module, versions 3.0.0-M1 through before 3.0.0-M4) lets an attacker who supplies a crafted serialized stream to the public static SvmDoccatModel.deserialize(InputStream) trigger deserialization of an arbitrary object graph before the SvmDoccatModel cast occurs. Where a usable gadget chain exists on the consuming application's classpath, this yields remote code execution in the loading JVM; OpenNLP ships no gadget itself, so realistic risk falls on downstream apps that embed the module alongside vulnerable transitive dependencies. No public exploit identified at time of analysis and the flaw is not in CISA KEV, though the SSVC assessment marks it automatable with partial technical impact.
Denial of service in Apache IoTDB versions 1.3.3 through 2.0.7 lets remote attackers crash the DataNode process by submitting a single query whose time span and aggregation interval are unbounded. Because the affected query interface enforces no reasonable limit on these parameters, a request combining a very large time range with a minimal interval forces the DataNode to materialize an enormous result set in memory, exhausting the Java heap. No public exploit has been identified at time of analysis and the issue is not in CISA KEV, but the fix is easy to reverse-engineer from the version bump to 2.0.8.
Remote code execution in the Apache Camel camel-hazelcast component allows an attacker who can join or reach the Hazelcast cluster to run arbitrary code on every Camel node. The flaw exists because Camel-created Hazelcast instances apply no Java deserialization filter by default, so crafted serialized objects sent over the cluster protocol are deserialized (ObjectInputStream.readObject) before Camel processes them. It affects Camel 4.0.0-4.14.7, 4.15.0-4.18.2, and 4.19.0-4.20.x whenever a hazelcast consumer or repository uses Camel's own default configuration; there is no public exploit identified at time of analysis and EPSS is low (0.49%, 39th percentile).
Remote code execution in Apache Camel's camel-vertx-http component (4.0.0-4.14.7, 4.15.0-4.18.2, 4.19.0) arises when a producer endpoint deserializes 5xx HTTP response bodies marked application/x-java-serialized-object through a raw java.io.ObjectInputStream with no class filtering. Exploitation is limited to non-default deployments where transferException=true or allowJavaSerializedObject=true is set and throwExceptionOnFailure remains true, letting an attacker who controls or intercepts the backend deliver a malicious serialized object and, given a gadget chain on the classpath, run code on the Camel host. This is a vendor-reported (Apache) issue with a publicly available advisory; there is no public exploit identified at time of analysis and EPSS is low at 0.39% (31st percentile).
Arbitrary file read in GravitLauncher LaunchServer ≤ 5.7.11 lets an unauthenticated remote attacker retrieve any file readable by the server process via a path-traversal in the default-enabled HTTP file server on port 9274. Because the exposed files include the ECDSA key that signs access JWTs (.keys/ecdsa_id), the refresh-token salt, and database credentials, the flaw escalates from information disclosure to a full authentication bypass allowing forged admin tokens. Publicly available exploit code exists (a raw-socket PoC in the advisory); the issue is not listed in CISA KEV and no active exploitation is confirmed.
Silent authentication downgrade in the OnGres SCRAM Java client (com.ongres.scram:scram-client and scram-common, versions <= 3.2) lets a TLS man-in-the-middle strip SCRAM-SHA-256-PLUS channel binding down to plain SCRAM-SHA-256, defeating clients that explicitly set channelBinding=require. The flaw only manifests when the server certificate uses a modern signature algorithm without a 'WITH' name (e.g., Ed25519 or post-quantum), causing the deprecated getChannelBindingData() API to swallow a NoSuchAlgorithmException and return an empty byte array that the builder misreads as 'no channel binding available.' No public exploit is identified at time of analysis, and it is not listed in CISA KEV; a vendor patch (3.3) is available.
Denial of service in OpenTelemetry Java Instrumentation before 2.27.0 lets an attacker who can reach an RMI endpoint on an instrumented JVM send an oversized context-propagation payload that triggers excessive memory allocation. The RMI payload reader caps the number of context entries but never bounds the aggregate size of the strings it reads, so a single crafted request can exhaust heap and crash or stall the JVM. No public exploit is identified at time of analysis, EPSS is low (0.24%), and CISA SSVC records no observed exploitation, but the flaw is network-reachable and unauthenticated wherever RMI instrumentation is enabled and exposed.
Insecure JNDI object instantiation in mchange-commons-java before 0.6.0 lets attackers who can influence deserialized data or JNDI Reference resolution coerce the library's JavaBeanObjectFactory into constructing arbitrary classes and setting their JavaBean properties, enabling JNDI injection and deserialization-gadget attacks. Because this library underpins mchange projects such as the c3p0 connection pool, any Java application that deserializes attacker-controlled objects or dereferences untrusted JNDI References through it is exposed; a demonstrated path abuses a Swing JEditorPane to force outbound HTTP requests from a trusted security domain. No public exploit identified at time of analysis and it is not in CISA KEV, so treat it as a patch-now supply-chain issue rather than an actively exploited one.
Unauthorized blob read, write, and delete operations in CrateDB's HTTP API allow any authenticated user to bypass privilege grants on blob tables. The HttpBlobHandler endpoint fails to enforce access control, enabling authenticated users to read, delete, or plant arbitrary blobs via crafted HTTP requests, regardless of their SQL-level permissions. Public proof-of-concept exploit code exists; a vendor patch is available, but active exploitation has not been confirmed through CISA KEV.
Arbitrary code execution in Amazon's AWS Advanced JDBC Wrapper (versions 3.3.0 through 4.0.0) arises from the RemoteQueryCachePlugin deserializing cached query results from Redis or Valkey via a raw ObjectInputStream with no class filtering. An actor able to write to the shared cache can poison entries with a crafted serialized Java object, triggering gadget-chain execution on every application server that later reads that cache entry. No public exploit identified at time of analysis; risk is elevated because a single poisoned cache key fans out to all consuming app servers.
Remote code execution in IBM WebSphere eXtreme Scale 8.6.1.0 through 8.6.1.6 arises from roughly 50 generated CORBA stub classes in the shipped ogclient.jar that invoke ORB.string_to_object() on an attacker-controlled IOR string during Java deserialization, converting any unfiltered ObjectInputStream sink in the surrounding WebSphere Application Server into outbound IIOP server-side request forgery. When chained with the IBM ORB getUserException class-instantiation flaw (tracked as WAS-26), that SSRF escalates to code execution on the calling JVM. CVSS is 10.0 (scope-changed, full CIA impact); EPSS is 3.01% (86th percentile) and there is no public exploit identified at time of analysis.
Unauthenticated remote code execution in Orkes Conductor (conductor-oss) versions 3.21.21 through 3.30.1 lets remote attackers run arbitrary OS commands by POSTing inline workflow definitions to the workflow API before any authentication check. The flaw stems from GraalVM script evaluators left in an unsandboxed state (HostAccess.ALL / allowAllAccess(true)), allowing JavaScript or Python expressions in INLINE, LAMBDA, DO_WHILE, and SWITCH tasks to reach Java reflection and subprocess APIs. Reported by VulnCheck; no public exploit identified at time of analysis, though a detailed vendor/researcher advisory exists.
Arbitrary VS Code command execution in the Red Hat vscode-java extension allows a malicious Java source file to embed hidden commands inside JavaDoc hover Markdown, so that a developer who simply clicks a crafted link in a hover popup triggers attacker-chosen commands that can escalate to full system compromise in trusted workspaces. The flaw stems from the extension rendering JavaDoc hovers as fully-trusted Markdown, and it also affects Red Hat OpenShift Dev Spaces, which bundles the extension. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the network reach combined with only a single click of user interaction makes it high-impact.
Arbitrary code execution in the OWASP ZAP ViewState add-on (versions before 4) lets a malicious or attacker-controlled proxied web server compromise the security tester's own ZAP instance. By embedding a crafted serialized Java object in the javax.faces.ViewState response parameter, an attacker triggers unsafe Java deserialization inside the ZAP JVM the moment the operator views the ViewState panel in the Desktop UI. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the vendor has published an advisory and shipped a fix (viewstate-v4) that disables JSF support entirely.
Unsafe Java deserialization in OpenAM Community Edition's Push Notification SNS callback route (through version 16.0.6) allows a low-privileged user who can start Push Registration to plant an attacker-controlled predicate blob in the CTS store, which OpenAM later loads by attacker-supplied class name and deserializes with Jackson when an anonymous SNS callback references the same messageId. The result is a reliable server-side class-loading and arbitrary-object-construction primitive that can corrupt push-token records and trigger classpath-dependent side effects such as process execution, file writes, or denial of service; the vendor explicitly states that arbitrary attacker-controlled code execution was not confirmed on stock classpaths, so real-world severity hinges on what classes are reachable in the deployment. The flaw is patched in 16.1.1 (commit ca15cba, GHSA-pp89-732f-3g8q); there is no CISA KEV listing and no public exploit code identified at time of analysis.
Authentication bypass in Apache Shiro affects deployments using the shiro-guice module in a web servlet context, where a specially crafted HTTP request can evade path-based access controls and reach protected resources without valid credentials. It mirrors the older shiro-spring flaw CVE-2020-1957 but targets the Guice integration instead, impacting all Shiro releases through 2.x and 3.0.0-alpha-1. No public exploit identified at time of analysis, though the CVSS 4.0 base score of 8.2 reflects high confidentiality impact and the close analogy to a previously exploited bug class.
Arbitrary code execution in QOS.CH logback-core versions up to and including 1.5.34 allows a local attacker with existing privilege to run code in the context of any Java application that loads Logback when the Janino library is on the classpath. The flaw circumvents prior hardening for CVE-2025-11226 via conditional configuration file processing, and is triggered either by writing to an existing logback configuration file or by injecting an environment variable that points the process at a malicious configuration. No public exploit identified at time of analysis, though the bypass nature of the issue makes weaponization of existing CVE-2025-11226 exploit code plausible.
Cross-tenant alarm destruction in OpenRemote Manager (versions before 1.25.0) allows any authenticated user with alarm-write permissions in their own realm to permanently delete alarm records belonging to other tenants by submitting arbitrary sequential alarm IDs to the bulk-delete endpoint. The flaw stems from missing per-record realm scoping in removeAlarms() and is rated CVSS 4.0 8.6 (high); no public exploit identified at time of analysis, but the GHSA advisory documents the exact vulnerable code path, making weaponization straightforward.
Remote code execution in Spring Statemachine 3.2.0-3.2.4 and 4.0.0-4.0.1 allows authenticated attackers to execute arbitrary code inside the application JVM by injecting malicious serialized Java objects into the Kryo-based persistence backends (JPA, MongoDB, Redis, or ZooKeeper). The flaw stems from deserializing persisted state-machine contexts without enforcing a class allowlist, a classic CWE-502 pattern that has historically yielded reliable gadget-chain exploitation in Java applications. No public exploit identified at time of analysis, but the deserialization sink and Kryo gadget ecosystem make weaponization straightforward once an attacker can write to the persistence store.
Unauthenticated remote code execution in Open Identity Platform's OpenDJ Community Edition (through 5.1.0) arises from Java deserialization of untrusted data in the JMX RMI connector, which reads and processes attacker-controlled bytes before authentication. Any attacker with TCP reachability to the configured JMX listener can deliver a malicious serialized object gadget chain and execute code on the directory server; the vendor demonstrated working RCE on OpenDJ 4.4.15 (JDK 11 + Jackson 2.12.6.1). No CISA KEV listing and no public exploit code identified at time of analysis, though a vendor proof-of-concept demonstration is documented in the advisory.
Remote code execution in Spinnaker's Rosco and Orca services arises because YAML input is parsed with SnakeYAML's unsafe default Constructor rather than a SafeConstructor, letting authenticated users who trigger CloudFormation deployments or CloudFoundry baking load arbitrary Java classes. An attacker with pipeline access can supply a crafted YAML tag (e.g. !!javax.script.ScriptEngineManager) to instantiate dangerous classes and reach code execution on the affected service host. No public weaponized exploit is identified, though the vendor fix commit ships tests demonstrating the arbitrary-object-instantiation primitive, and the flaw is not listed in CISA KEV.
Authentication bypass in Quarkus Java framework allows remote unauthenticated attackers to circumvent HTTP path-based authorization policies by smuggling encoded semicolons (%3B) as matrix parameters or by using encoded slashes (%2F) and backslashes (%5C) to reach protected static resources. Affects all Quarkus versions prior to the 3.37.0, 3.36.3, 3.33.2.1, 3.33.3, 3.27.4.1, 3.27.5, and 3.20.6.2 patch line. No public exploit identified at time of analysis, though the issue is a documented bypass of the prior CVE-2026-39852 fix.
Cedar policy injection in CedarJava (com.cedarpolicy:cedar-java) versions below 2.3.6, 3.4.1, and 4.9.0 allows attackers to alter authorization outcomes by smuggling Cedar expressions through unescaped string values. The flaw is in toCedarExpr() on Cedar Value types, which fails to escape quote and backslash characters when serializing user-controlled values into policy text. No public exploit identified at time of analysis, but the integrity impact is severe because injected fragments like '|| true' can neutralize permit/forbid logic in fine-grained authorization decisions.
Type confusion in CedarJava versions prior to 2.3.6, 3.4.1, and 4.9 allows authenticated remote attackers to manipulate authorization decisions by injecting reserved JSON keys (`__entity` or `__extn`) into CedarMap objects built from attacker-controlled input. When an integrating service constructs a CedarMap from caller-supplied data such as headers, metadata, or resource tags, the Rust cedar-policy evaluator can be tricked into interpreting a record as an entity reference, undermining fine-grained authorization. No public exploit identified at time of analysis, but the CVSS 8.8 rating reflects high impact on confidentiality, integrity, and availability of authorization outcomes.
Denial of service in Steeltoe.Discovery.Eureka client (.NET) versions prior to 4.2.0 and 3.4.0 allows a remote Eureka registry containing service registrations with DataCenterInfo.name="Netflix" to permanently break the local service discovery cache. The client's DataCenterInfo.FromJson rejects any value other than "MyOwn" or "Amazon" with an ArgumentException that is silently swallowed by the periodic cache refresh task, leaving downstream .NET services unable to discover peers. No public exploit identified at time of analysis, but the trigger is trivially reachable in mixed Java/Spring-Cloud and Steeltoe environments.
XML External Entity injection in the HAPI FHIR core library (Maven ca.uhn.hapi.fhir:org.hl7.fhir.utilities, versions <= 6.9.9) lets an attacker who controls or MITMs XML routed through XsltUtilities.saxonTransform(...) read local files and perform blind XXE/SSRF. The three saxonTransform overloads instantiate a bare net.sf.saxon.TransformerFactoryImpl that resolves external general and parameter entities, unlike the co-located transform() siblings that use the project's hardened XXE-protected factory. Publicly available exploit code exists (a full end-to-end PoC accompanies the GitHub advisory), though there is no public exploit identified as actively used in the wild.
Regular expression denial of service in HAPI FHIR's DSTU2 FHIRPathEngine allows unauthenticated remote attackers to exhaust server CPU by submitting FHIR resources or FHIRPath expressions containing catastrophically backtracking regexes against the matches() function. This is an incomplete-fix vulnerability stemming from CVE-2026-45367, where the DSTU2 module's matches() at FHIRPathEngine.java line 2462 was left calling raw String.matches() without the RegexTimeout wrapper applied to the other five FHIR version modules. No public exploit identified at time of analysis beyond the reporter's working PoC published in the GHSA advisory.
Arbitrary file read in jknack handlebars.java versions prior to 4.5.2 allows remote unauthenticated attackers to retrieve files outside the intended template directory when applications pass user-controlled input to Handlebars.compile() with a FileTemplateLoader or ClassPathTemplateLoader. The flaw stems from missing path canonicalization in the template loaders, enabling classic ../ traversal sequences to escape the configured template prefix. No public exploit identified at time of analysis, but the GitHub Security Advisory GHSA-r4gv-qr8j-p3pg documents the issue and the fix is available in 4.5.2.
Local denial of service in Android's PackageInstaller subsystem stems from a logic error in PackageInstallerSession.transfer() that allows a local app to trigger memory exhaustion of the system package installer. The flaw, addressed in the Android Security Bulletin for Android 17, can be triggered without user interaction and without elevated privileges, but its impact is confined to denial of service rather than code execution. No public exploit identified at time of analysis.
Origin validation failure in Spring Cloud Gateway (WebMVC and WebFlux Server variants) allows remote attackers to spoof client identity by injecting X-Forwarded-For and Forwarded headers that the gateway then forwards from untrusted proxies in certain configuration scenarios. The flaw, tracked as CVE-2026-47825 with a CVSS 3.1 base score of 8.6 (Scope:Changed, Integrity:High), affects Spring Cloud Gateway 3.1.x, 4.1.x, 4.2.x, 4.3.x, and 5.0.x. No public exploit identified at time of analysis, but the trust-boundary nature of the issue makes it an attractive target for downstream authentication and access-control bypass.
Denial-of-service in Spring Cloud Sleuth 3.1.0 through 3.1.13 allows remote unauthenticated attackers to exhaust application availability by sending specially crafted calls processed by the spring-cloud-sleuth-instrumentation library when Spring TX (transaction) instrumentation is enabled. The flaw is network-reachable with low attack complexity and no user interaction (CVSS 7.5, AV:N/AC:L/PR:N), but there is no public exploit identified at time of analysis and no CISA KEV listing. Impact is limited to availability - no confidentiality or integrity compromise is possible.
NoSQL/query injection in Spring AI Vector Stores (1.0.0-1.0.8 and 1.1.0-1.1.7) allows remote unauthenticated attackers to inject special characters into vector-store inputs and force execution of arbitrary queries against Elasticsearch, OpenSearch, and GemFire VectorDB backends. The flaw resides in the spring-ai-elasticsearch-store, spring-ai-opensearch-store, and spring-ai-gemfire-store components, enabling information disclosure and limited integrity/availability impact against any application embedding Spring AI's vector-store abstraction. No public exploit identified at time of analysis, but the CVSS 8.6 (scope unchanged here, network vector, no privileges) makes this a high-priority patch for any Spring AI deployment ingesting untrusted text.
Improper access control in File Browser (filebrowser/filebrowser, Go) versions <= 2.63.6 lets a user with share/download permissions create a public share for a path that does not yet exist; because the share record stores only a path string and is never bound to a concrete object, the link silently begins exposing whatever file later appears at that path via GET /api/public/dl/<hash>. The flaw mirrors the Android MediaProvider issue CVE-2026-0035 — the create handler omits an existence check before persisting the share. EPSS is very low (0.02%, 6th percentile) and there is no public exploit identified at time of analysis, but a step-by-step PoC is included in the GitHub Security Advisory.
Authorization bypass in Spring for GraphQL (versions 1.0.0-1.0.6, 1.3.0-1.3.8, 1.4.0-1.4.5, and 2.0.0-2.0.3) allows remote attackers to invoke @Controller data fetcher methods whose security annotations are declared on parent classes or interfaces, because the framework's annotation detection does not consistently resolve annotations across type hierarchies. The flaw is rated CVSS 7.5 (confidentiality-only impact) and no public exploit identified at time of analysis, but the network-reachable, no-privilege CVSS vector makes any affected GraphQL endpoint a meaningful exposure.
Cross-Site WebSocket Hijacking in Spring for GraphQL allows remote attackers to execute arbitrary GraphQL operations under an authenticated victim's identity when the application has enabled the GraphQL WebSocket transport. The flaw stems from missing origin validation on WebSocket handshakes (CWE-346), affecting Spring for GraphQL 1.0.x, 1.3.x, 1.4.x, and 2.0.x branches up to 2.0.3. No public exploit identified at time of analysis, but the high CVSS (8.1) and reliance only on a single victim click make this a meaningful risk for any deployment exposing the WebSocket endpoint.
Remote code execution in Spring for GraphQL versions 1.3.0-1.3.8, 1.4.0-1.4.5, and 2.0.0-2.0.3 allows unauthenticated attackers to trigger unsafe deserialization by sending crafted paginated GraphQL queries against Connection-type fields. Exploitation requires that the application expose a paginated (Connection) field and that the classpath contains gadget classes leveraged during deserialization. No public exploit identified at time of analysis; EPSS sits at 0.34% (57th percentile) and the issue is not in CISA KEV, but a vendor patch is available.
Improper certificate validation in Apereo CAS Client 4.1.0 and Jasig CAS Client 3.6.4 allows a man-in-the-middle attacker to intercept Ticket-Granting Tickets (TGTs) by presenting any CA-signed certificate for a hostname matching the client's allowlist. An attacker with a network interception position can then obtain service tickets on behalf of the victim. No active exploitation or public exploit code is confirmed, and EPSS indicates low exploitation probability (0.17%).
Authentication bypass in Eclipse Jetty's HTTP Digest authentication implementation allows an unauthenticated attacker who knows a target username to authenticate as any user whose password contains non-Latin-1 characters (CJK, Cyrillic, Arabic, Greek, emoji, etc.) by substituting those characters with literal '?' characters. The root defect is in DigestAuthentication.java, which uses ISO-8859-1 encoding at three points when computing H(A1), H(A2), and the final MD5 response hash - silently collapsing all code points above U+00FF to 0x3F, making collision credentials cryptographically indistinguishable from the original. A publicly available proof-of-concept demonstrates hash collision across Chinese, Korean, Cyrillic, and Greek passwords; no active exploitation has been confirmed by CISA KEV at time of analysis.
Takeover of Oracle Platform Security for Java (OPSS) is possible where a low-privileged attacker with HTTP network access can fully compromise the confidentiality, integrity, and availability of the service. The flaw resides in the Centralized Thirdparty Jars component and affects Oracle Fusion Middleware releases 12.2.1.4.0 and 14.1.2.0.0. It carries a CVSS 3.1 base score of 8.8 and was disclosed in the Oracle Critical Patch Update of July 2026; no public exploit identified at time of analysis.
Full compromise of Oracle Platform Security for Java (OPSS) in Oracle Fusion Middleware 12.2.1.4.0 and 14.1.2.0.0 is possible by a low-privileged attacker over HTTP, targeting the Centralized Thirdparty Jars component. Oracle rates the flaw 8.8 and describes it as 'easily exploitable,' with successful attacks yielding complete takeover (high confidentiality, integrity, and availability impact). No public exploit is identified at time of analysis and the CVE is not listed in CISA KEV.
Full compromise of Oracle Platform Security for Java (OPSS) in Oracle Fusion Middleware versions 12.2.1.4.0 and 14.1.2.0.0 allows a low-privileged attacker with network access over HTTP to take over the component, per Oracle's July 2026 Critical Patch Update. The flaw yields high confidentiality, integrity, and availability impact and is rated easily exploitable (CVSS 8.8), though no public exploit identified at time of analysis. Because OPSS underpins authentication, authorization, and credential management for the wider Fusion Middleware stack, a takeover has cascading security consequences.
Full compromise of Oracle Platform Security for Java (OPSS), a security framework within Oracle Fusion Middleware, is possible when a low-privileged attacker reaches the affected instance over HTTP via the Centralized Thirdparty Jars component. Oracle rates the flaw CVSS 3.1 8.8 and describes it as "easily exploitable," resulting in a complete takeover of OPSS with high confidentiality, integrity, and availability impact. No public exploit identified at time of analysis and it is not in CISA KEV, but the low attack complexity and only a low-privilege authenticated prerequisite make it a strong candidate for prompt patching in Oracle environments.
Full compromise ("takeover") of Oracle Platform Security for Java (OPSS), a core security framework shipped inside Oracle Fusion Middleware, is possible by an unauthenticated remote attacker over HTTP against versions 12.2.1.4.0 and 14.1.2.0.0. Oracle rates this 9.8 with full confidentiality, integrity, and availability loss and describes it as "easily exploitable," so it should be treated as a top-priority patch in the July 2026 Critical Patch Update. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the trivial exploitation profile (no authentication, no user interaction) makes it an attractive target once details or patches are reverse-engineered.
Full takeover of Oracle Platform Security for Java (OPSS), a security framework within Oracle Fusion Middleware, is possible for a low-privileged attacker positioned on the same physical communication segment as the host. Disclosed in Oracle's July 2026 Critical Patch Update, the flaw carries a CVSS 3.1 score of 8.0 and a scope change, meaning successful exploitation can significantly impact additional products beyond OPSS itself. Exploitation is rated difficult (AC:H) and there is no public exploit identified at time of analysis, so risk is elevated by potential blast radius rather than by ease of attack.
Full takeover of Oracle Platform Security for Java (OPSS), a security framework bundled with Oracle Fusion Middleware 12.2.1.4.0 and 14.1.2.0.0, is possible via its Centralized Thirdparty Jars component. A low-privileged attacker with HTTP network access can compromise confidentiality, integrity, and availability, though the attack is rated difficult to execute (high attack complexity). No public exploit identified at time of analysis and the flaw is not in CISA KEV, but it was disclosed by Oracle in the July 2026 Critical Patch Update.
Full compromise of Oracle Platform Security for Java (OPSS) in Oracle Fusion Middleware versions 12.2.1.4.0 and 14.1.2.0.0 is achievable by a low-privileged attacker over HTTP through the Centralized Thirdparty Jars component. Because the flaw carries a scope change, successful exploitation can result in complete takeover of OPSS and significantly impact additional connected products, earning a near-maximum CVSS 3.1 base score of 9.9. No public exploit has been identified at time of analysis, but the low attack complexity and minimal privilege requirement make this a high-priority patch.
Full takeover of Oracle Platform Security for Java (OPSS) is possible in Fusion Middleware versions 12.2.1.4.0 and 14.1.2.0.0, where a low-privileged attacker with network access can compromise the component via crafted SOAP requests. Oracle rates this CVSS 8.8 with high confidentiality, integrity, and availability impact, meaning successful exploitation yields complete control of the OPSS component rather than mere data exposure. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Remote takeover of Oracle Platform Security for Java (OPSS), a security framework bundled with Oracle Fusion Middleware versions 12.2.1.4.0 and 14.1.2.0.0, allows an unauthenticated attacker with HTTP network access to fully compromise the component. Rated CVSS 3.1 9.8 with high confidentiality, integrity, and availability impact, Oracle describes it as 'easily exploitable' via the Centralized Thirdparty Jars component. No public exploit has been identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and lack of authentication make it a high-priority patch.
Complete takeover of Oracle Platform Security for Java (OPSS) in Oracle Fusion Middleware 12.2.1.4.0 and 14.1.2.0.0 is possible by an unauthenticated remote attacker over HTTP, per Oracle's July 2026 Critical Patch Update. The flaw resides in the 'Centralized Thirdparty Jars' component and carries a maximum CVSS 3.1 base score of 10.0 with a scope change, meaning successful exploitation can significantly impact products beyond OPSS itself. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the perfect CVSS score and 'easily exploitable' vendor language make this a top-priority patch.
TLS certificate-revocation bypass in Netty's OcspServerCertificateValidator (netty-handler-ssl-ocsp, versions <4.1.136.Final and 4.2.0.Final-4.2.16.Final) allows a malicious server presenting a revoked certificate to receive sensitive client data during a race window. The validator forwards the SslHandshakeCompletionEvent to downstream handlers before the asynchronous OCSP check finishes, so client applications treat the connection as trusted and may transmit or process application data before the revoked channel is closed. Publicly available exploit code exists (PoC in the GHSA advisory); no public active exploitation has been reported and the vulnerability is not in CISA KEV.
Certificate revocation bypass in the Netty netty-handler-ssl-ocsp module (versions before 4.1.136.Final, and 4.2.0.Final through 4.2.15.Final) lets an on-path attacker replay a stale, expired-but-GOOD OCSP response to make OcspServerCertificateValidator accept a certificate that has since been revoked. A missing return statement after the freshness check causes execution to fall through and still fire a VALID OcspValidationEvent even after flagging the response as out-of-date. Publicly available exploit code exists (a PoC unit test is embedded in the GHSA advisory); the issue is not listed in CISA KEV and no EPSS score was provided.
Local privilege escalation to full takeover in the Install component of Oracle Java SE (8u491, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1), Oracle GraalVM for JDK (17.0.19, 21.0.11), and Oracle GraalVM Enterprise Edition (21.3.18) lets a low-privileged local user compromise the runtime and take it over with full confidentiality, integrity, and availability loss. Oracle rates it 7.8 (High) and describes it as easily exploitable by an attacker holding only a logon to the host. No public exploit has been identified at time of analysis and it is not on CISA KEV.
Unauthorized data modification in Oracle Java SE, GraalVM for JDK, and GraalVM Enterprise Edition (Libraries component) lets a remote, unauthenticated attacker corrupt, create, or delete critical data by feeding crafted input to affected Java APIs, for example through a web service that passes data to those APIs. It carries CVSS 3.1 7.5 with an integrity-only impact (C:N/I:H/A:N) and is described by Oracle as easily exploitable over multiple network protocols. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the ubiquity of the Java runtime makes patching a priority.
Unauthorized data access and modification in the Scripting component of Oracle Java SE 8u491, 8u491-perf, and 11.0.31 allows a remote unauthenticated attacker to compromise the confidentiality and integrity of all Java-accessible data via APIs reachable over multiple network protocols. Rated CVSS 3.1 7.4 (High) by Oracle, the flaw is difficult to exploit (AC:H) and carries no availability impact; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. It also affects sandboxed Java Web Start/applet deployments that run untrusted code and rely on the Java sandbox.
Denial-of-service in Oracle Java SE 8u491 (and 8u491-perf) and 11.0.31 lets an unauthenticated remote attacker hang or repeatedly crash the JVM by feeding crafted input to the Scripting component's APIs, for example via a web service that passes data to those APIs. There is no confidentiality or integrity impact - only availability - but the attack is network-reachable, low-complexity, and requires no authentication or user interaction, yielding a CVSS 7.5. No public exploit identified at time of analysis and the flaw is not on CISA KEV.
Remote denial of service in the Netty networking framework (codec-haproxy module) versions 4.1.0.Final through 4.1.135 and 4.2.0.Final through 4.2.15.Final lets unauthenticated attackers exhaust JVM direct memory. The HAProxyMessageDecoder mis-parses a PROXY protocol v2 header whose version byte is 0xFF, sign-extending it to -1, which collides with the decoder's 'need more data' sentinel, so ByteToMessageDecoder accumulates inbound bytes in an unbounded cumulation buffer until the process runs out of direct memory. No public exploit identified at time of analysis; the CVSS 4.0 score of 8.7 reflects high availability impact with no confidentiality or integrity effect.
Remote code execution risk in Apache Fory (the Java serialization framework formerly known as Fury) before 1.4.0 arises because attacker-supplied data can bypass the class-registration allowlist during Java lambda deserialization, with the gap confined to the lambda capture class. Registration checks are Fory's core defense against untrusted-deserialization gadget attacks, so bypassing them for lambda payloads can let an attacker instantiate otherwise-disallowed classes and reach code execution or memory corruption. There is no public exploit identified at time of analysis and this CVE is not listed in CISA KEV; the vendor (Apache) rates it CVSS 9.8 and a fixed release (1.4.0) is available.
SQL injection in AiFlowy versions 2.1.2 and earlier lets remote attackers extract sensitive database contents through the getPageData method in DatacenterQuery.java. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) indicates unauthenticated, low-complexity network exploitation with high confidentiality impact but no integrity or availability effect. A public technical write-up with reproduction details exists on GitHub, though the low EPSS score (0.19%, 8th percentile) and absence from CISA KEV indicate no confirmed active exploitation at time of analysis.
Information disclosure in aiflowy (an open-source Java/Spring-based AI workflow / low-code platform) versions 2.1.2 and earlier lets remote unauthenticated attackers extract sensitive information through the JobUtil.java scheduling component. The public technical writeup titled 'Any SpringBean invocation' indicates the flaw stems from unrestricted invocation of arbitrary Spring beans, which can be abused to read internal application state and secrets. No CISA KEV listing and a low EPSS score (0.19%, 9th percentile) suggest no observed mass exploitation, but a public technical analysis describing the technique exists.
Path traversal in Apache MINA SSHD's sshd-git component lets an authenticated remote user on Windows-hosted git servers escape the configured server-side root directory and reach git repositories elsewhere on the filesystem. It is an incomplete-fix regression of CVE-2026-48827: the path validation added in 2.18.0 and 3.0.0-M4 was only partly effective on Windows path semantics. No public exploit identified at time of analysis; not listed in CISA KEV, and no EPSS score was provided.
Command-restriction bypass in Apache MINA SSHD (server-side) lets a user who authenticates with an OpenSSH user certificate carrying a force-command directive execute arbitrary commands instead of the single restricted command the certificate authority intended. The server accepts and honors such certificates but silently ignores the force-command and verify-required options, breaking the security model that certificate issuers rely on to constrain principals. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the flaw is confirmed and fixed by the Apache Software Foundation in versions 2.19.0 and 3.0.0-M5.
Arbitrary file write in Apache MINA SSHD's sshd-scp component lets a malicious SCP sender place files outside the intended download directory because filenames in SCP 'C' (file) and 'D' (directory) commands are not validated for path separators. Any application acting as an SCP receiver - either an SSHD server accepting uploads or an SCP client fetching from a server - using unsupported versions <2.0.0 or the sshd-scp module in >=2.0.0 is affected, allowing an attacker to overwrite or plant files in attacker-chosen locations. Reported by Apache; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Privilege escalation in Apache Syncope's identity-management engine lets a self-service user grant themselves defined Roles via a single REST API call, effectively promoting a low-privileged or newly self-registered account to administrator. It affects deployments running the all-Java user workflow adapter, or the Flowable adapter with a BPMN definition that does not require admin approval for self-registration or self-update, across versions 3.0.0-M0-3.0.16, 4.0.0-M0-4.0.6, and 4.1.0-M0-4.1.1. The Apache-issued advisory rates it CVSS 9.8; no public exploit identified at time of analysis and it is not on CISA KEV.
Unauthenticated remote denial of service in the JLine3 remote-telnet server module (versions before 3.30.14, 4.0.16, and 4.2.1) lets an attacker crash the JVM by flooding the Telnet NEW-ENVIRON negotiation with unbounded unique environment-variable pairs. Because TelnetIO.readNEVariables() stores every pair in an uncapped HashMap on ConnectionData before login, roughly 3-4 MB of traffic can exhaust a 512 MB heap and force an OutOfMemoryError. No public exploit code is identified, but the vendor advisory (GHSA-47qp-hqvx-6r3f) documents proof-of-concept methodology; the flaw is not listed in CISA KEV and no EPSS score was supplied.
Denial of service in the JLine3 Telnet server (jline-remote-telnet module) lets an unauthenticated remote attacker exhaust server CPU by abusing the Telnet NAWS window-size option. Because TelnetIO enforces only a lower bound on terminal dimensions, a client can advertise a 65535x65535 terminal and repeatedly alternate values to force continuous, expensive redisplay/rendering cycles. Publicly available exploit code exists (a raw two-packet Telnet PoC is published in the vendor GHSA advisory), and there is no public exploit identified as being actively exploited; the issue is fixed in 3.30.14, 4.0.16, and 4.2.1.
SQL injection in cool-admin-java 8.0.0 lets attackers inject arbitrary SQL through the order() method of CrudOption.java, a shared CRUD helper used across the framework's auto-generated data endpoints. The flaw carries an NVD CVSS of 9.8 (CWE-89) and, if reachable without authentication as the vector implies, permits full read/write access to the backing database. There is no public exploit identified at time of analysis and EPSS is low (0.14%, 4th percentile), indicating minimal observed exploitation activity so far.
Missing-authorization schema tampering in ArcadeDB before 26.6.1 lets any authenticated identity - including a read-only API token that lacks the UPDATE_SCHEMA permission - mutate the database schema over the HTTP command/query endpoints. Because CVE-2026-44221's fix only added the UPDATE_SCHEMA check to LocalDocumentType.createProperty, the remaining schema mutators (DROP PROPERTY, ALTER TYPE, ALTER PROPERTY, type/bucket/alias changes) stayed unguarded, so a low-privilege user can drop properties, rename or re-parent types, and flip property constraints, corrupting the meaning of every stored record. There is no public exploit identified at time of analysis and it is not in CISA KEV, but the vendor advisory (GHSA-vg6x-6pg9-6qwg) confirms the flaw and a fix in 26.6.1.
Server-Side Request Forgery and arbitrary local file read in ArcadeDB before 26.6.1 let any authenticated user with SQL command/query access - not just root/administrators - abuse the SQL `IMPORT DATABASE` statement, whose source URL was passed to the importer unchecked. Because it required no administrative privileges, a low-privileged user could force the server to fetch arbitrary HTTP(S) endpoints (including cloud metadata at 169.254.169.254 and internal-only services) and ingest the responses as queryable records, or read local files such as `/etc/passwd` and credential files via `file://` paths. No public exploit identified at time of analysis; the flaw was privately reported and fixed in release 26.6.1.
Build-time remote code execution in Nuclio (serverless/FaaS platform) versions <= 1.15.27 lets remote attackers run arbitrary OS commands as root inside the function-builder container. The Java runtime renders user-supplied runtimeAttributes.repositories values into a Groovy build.gradle file via Go's text/template using the non-escaping {{ . }} action, so an attacker can inject a closing brace to break out of the repositories {} block and append Groovy that Gradle executes during its configuration phase. Because the Dashboard API defaults to NOP (no) authentication, exploitation needs no credentials; a dynamically-verified proof-of-concept is published in the vendor advisory, though there is no public exploit identified as being used in active attacks.
Authentication/access-control bypass in BigBlueButton's bbb-web component (versions prior to 3.0.21) lets remote attackers reach protected API endpoints without a valid checksum by supplying the presentationUploadExternalUrl parameter. BigBlueButton's API is normally guarded by a shared-secret checksum, so bypassing it undermines the core authorization mechanism for calls such as CreateMeeting. No public exploit identified at time of analysis, though the fixing commit is public; CVSS is 8.1 and there is no CISA KEV listing or EPSS signal in the provided data.
Session hijacking in BigBlueButton before 3.0.21 lets an authenticated conference participant predict and reuse other users' session tokens to impersonate them. The bbb-web component generated 16-character sessionToken values (and 12-character auth tokens and internal user IDs) using Apache Commons RandomStringUtils.randomAlphanumeric, a non-cryptographic PRNG, making the token space guessable to anyone who already holds a valid session. Rated CVSS 8.1 with high confidentiality and integrity impact; no public exploit identified at time of analysis.
Authentication bypass in VMware/Spring's Spring Authorization Server (versions 7.0.0-7.0.4, 1.5.0-1.5.6, 1.4.0-1.4.9, and 1.3.0-1.3.10) allows a low-privileged authenticated actor to circumvent authentication controls and access protected resources across a security boundary. The CVSS 9.6 (Critical) rating reflects a scope change with high confidentiality and integrity impact but no availability effect. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the near-maximum score in a widely deployed OAuth2/OIDC authorization component makes this a high-priority patch.
Remote authenticated code execution in DataEase before 2.10.23 lets a low-privileged user abuse the Excel/datasource upload workflow to run arbitrary Java. By uploading a crafted payload.zip via /datasource/upload and defining an H2 datasource that references the archive through the zip: protocol, an attacker forces CalciteProvider.jdbcFetchResultField to execute a query that triggers precompiled Java aliases embedded in test.mv.db. The vendor CVSS 4.0 vector scores this 7.1 (confidentiality-only), but the underlying primitive is full arbitrary code execution; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Arbitrary file write leading to code execution in jadx 1.5.2 through 1.5.5 allows a malicious .xapk sample to escape the XAPK plugin unpack directory and plant a JAR under plugins/dropins, which the next jadx launch loads and executes via URLClassLoader/ServiceLoader. The flaw stems from XApkLoader calling tmpDir.resolve(fileName) after a flawed CWD-based ZIP name check, giving an analyst opening a crafted file a path traversal that escalates to attacker-controlled plugin code. Publicly available exploit code exists (SSVC exploitation: poc) but it is not in CISA KEV, and EPSS is very low at 0.13% (3rd percentile), consistent with a local, user-interaction-gated, high-complexity issue rather than mass exploitation.
Arbitrary Groovy code execution in the jadx Dex-to-Java decompiler (prior to 1.5.6) allows a malicious APK to run attacker-controlled code on the analyst's machine. When jadx exports a decompiled APK as an Android Gradle project, it copies the android:versionName value from AndroidManifest.xml into the generated build.gradle Groovy template without sanitization, letting a crafted value break out of the string literal and inject code that executes when the victim opens or builds the exported project. No public exploit identified at time of analysis; EPSS risk is low (0.15%, 5th percentile) and CISA SSVC records exploitation as none, but the technical impact is total.
Denial of service in the Netty netty-codec-stomp module (versions 4.1.x up to 4.1.135.Final and 4.2.0.Alpha1 through 4.2.15.Final) allows a remote attacker to trigger an OutOfMemoryError and crash the JVM. The StompSubframeDecoder caps individual header line length via maxLineLength but never bounds the total header count or cumulative header size, so a single STOMP frame packed with thousands of short headers exhausts heap memory. Publicly available exploit code exists (a working client/server PoC is published in the GitHub Security Advisory), but there is no public evidence of active exploitation; EPSS/KEV signals are not present in the input.
Privilege elevation in Microsoft Azure Spring Apps allows an already-authenticated, low-privileged network attacker to gain higher privileges by abusing an improper authentication weakness (CWE-287) in the managed platform. Because the CVSS scope is marked as changed (S:C), a successful attack can reach resources beyond the attacker's originally authorized boundary, yielding high confidentiality and integrity impact. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV; Microsoft has published an advisory and a patch is available server-side.
Unauthenticated arbitrary file write in Eclipse BaSyx Java Server SDK (2.0.0-milestone-05 through 2.0.0-milestone-12) lets remote attackers plant files anywhere the Java process can write when the server is deployed with the MongoDB file backend, potentially escalating to remote code execution. The AAS thumbnail API trusts a client-supplied fileName that is later reused as a filesystem path, so a traversal or absolute-path filename lands attacker-controlled bytes outside the intended directory. There is no public exploit identified at time of analysis and the issue is not in CISA KEV, but the vendor-fixed release (2.0.0-milestone-13) is available.
Reflected cross-site scripting in SAP NetWeaver Application Server Java (specifically the Configuration Wizard component) lets an unauthenticated attacker embed malicious JavaScript in crafted URLs that executes in a victim's browser when the link is opened. Because the CVSS scope is changed (S:C) and confidentiality impact is high, a successful lure can expose sensitive session information and tamper with non-sensitive data rendered in the client. No public exploit identified at time of analysis, but the 8.2 CVSS and unauthenticated, network-reachable vector make it a meaningful phishing-driven risk for exposed SAP portals.
Server-side request forgery in codecentric Spring Boot Admin Server before 4.1.2 lets unauthenticated remote attackers register a monitored instance with attacker-controlled healthUrl and managementUrl values that are never validated against private IP ranges or cloud metadata endpoints. Because the server then fetches those URLs and exposes the response bodies through its actuator proxy, an attacker can pivot into internal networks and read back sensitive data such as cloud instance-metadata credentials. Publicly available exploit code exists and the flaw was reported by VulnCheck, though there is no public exploit identified as actively exploited (not in CISA KEV).
Incorrect equality comparison in CedarJava (cedar-java) versions before 4.9.0 causes EntityIdentifier.equals() to return true when comparing against null and false when comparing an object to itself, due to inverted null/self-reference branches. Cedar's actual authorization decisions are unaffected because they are computed in Rust from JSON, but integrators who call equals() on entity identifiers in their own Java logic may make incorrect trust or access decisions. No public exploit identified at time of analysis; the issue is fixed in 4.9.0.
Remote code execution in Mura CMS versions prior to 10.0.712 allows unauthenticated attackers to execute arbitrary CFML and instantiate malicious Java objects by abusing the unvalidated 'method' parameter in POST requests to the /index.cfm/_api/json/v1/default JSON API endpoint. Because the ColdFusion engine processes the attacker-controlled input without sanitisation, a single crafted request yields full compromise (VC:H/VI:H/VA:H). No public exploit identified at time of analysis, though CISA SSVC flags the flaw as automatable with total technical impact.
Unsafe reflection in Apache IoTDB's pipe processor lets a user-supplied fully qualified Java class name be loaded and instantiated via Class.forName().newInstance() with no allowlisting, enabling arbitrary class loading and likely remote code execution in the database server process. It affects all releases from 1.0.0 up to (but not including) 2.0.10 and is fixed in 2.0.10. No public exploit identified at time of analysis, and EPSS is low (0.25%, 17th percentile), though CISA SSVC rates the technical impact as total and considers exploitation automatable.
Remote code execution in Metabase's H2 database driver allows an authenticated user with native-query privileges to run arbitrary Java on the server. When Metabase returns H2 result columns of type OTHER (JDBC JAVA_OBJECT), it deserializes the embedded Java object without validation, so a crafted native H2 query triggers CWE-502 unsafe deserialization and full server compromise. It affects any instance using an H2 connection, including the default bundled sample database. No public exploit is identified at time of analysis (SSVC exploitation: none; EPSS 0.45%), though the upstream fix commit and vendor advisory GHSA-w95f-x9v9-wv36 are public.
Remote code execution in Metabase (open-source BI/analytics platform) versions 1.55.0 through the fixed releases arises because one database-creation code path failed to validate unsafe H2 JDBC connection properties, letting an authenticated administrator register a crafted H2 datasource and run arbitrary Java on the server host. Because the CVSS scope is Changed (S:C), successful exploitation escapes the application context and yields full host compromise. No public exploit has been identified at time of analysis and it is not listed in CISA KEV, but the CVSS base score of 9.1 and RCE nature make it a high-priority patch for any exposed Metabase instance.
Remote code execution in DSpace 8.0-8.3 and 9.0-9.2 allows an authenticated administrator to execute arbitrary Java via Velocity templates used to render COAR Notify/LDN messages, using reflection to escape the templating sandbox. Exploitation requires valid DSpace administrator credentials and is most impactful when chained with the related LDN path-traversal flaw (GHSA-9qm4-rh6w-pq5x). No public exploit identified at time of analysis, and CVSS is 8.0 (High).
Remote code execution in Apache Gravitino before 1.2.1 allows unauthenticated callers to abuse the testConnection API by submitting a crafted H2 JDBC URL whose INIT parameter runs arbitrary Java on the server. The flaw only manifests when Gravitino is backed by the H2 database - a configuration primarily used for testing and local development - and CISA SSVC rates technical impact as total and exploitation as automatable, though no public exploit has surfaced. Fixed in 1.2.1; because Gravitino is usually deployed on internal networks and H2 is not the production default, the vendor characterizes real-world severity as low despite the 9.1 CVSS score.
Sensitive information disclosure in OneBlog V2.3.9 lets remote unauthenticated attackers retrieve WeChat Official Account secrets - the access_token and jsapi_ticket - through unprotected REST endpoints backed by RestApiController.java, JsApiTicketComponent.java, and GetAccessTokenComponent.java. Because these credentials grant control over the linked WeChat public account, disclosure enables account takeover of the integration rather than just data leakage. Classified CWE-306 (Missing Authentication); a referenced public gist appears to contain proof-of-concept details, though EPSS is low (0.26%, 18th percentile) and it is not listed in CISA KEV.
Arbitrary file read in OpenRemote's KNXProtocol asset-import handler lets any authenticated user (PR:L, any realm) upload a malicious ETS project ZIP whose 0.xml is parsed via Saxon XSLT and XMLInputFactory without XXE hardening, resolving external entities to exfiltrate server files such as /etc/passwd, openmrs-runtime.properties, and cloud credential files, with SSRF against internal endpoints as a secondary impact. This is an incomplete-fix regression of CVE-2026-40882, which only hardened the parallel Velbus handler and left KNXProtocol's two XML parsing calls unprotected. A full working proof-of-concept reproducing both parsing stages is publicly available; the vulnerability is not listed in CISA KEV.
Cross-tenant information disclosure in OpenRemote Manager lets a realm admin of one tenant read the profile, realm roles, and client roles of any user in any other realm - including the privileged master realm - simply by supplying the target user's UUID in the REST API path. Three read endpoints in UserResourceImpl verify the caller's read:admin role but never confirm the target user belongs to the caller's realm, breaking multi-tenant isolation for user data. Publicly available exploit code exists (a working curl-based PoC with live-instance HTTP 200 responses is documented), though it is not listed in CISA KEV and no active exploitation is confirmed.
Untrusted Java deserialization in Apache OpenNLP's SvmDoccatModel (libsvm document categorization module, versions 3.0.0-M1 through before 3.0.0-M4) lets an attacker who supplies a crafted serialized stream to the public static SvmDoccatModel.deserialize(InputStream) trigger deserialization of an arbitrary object graph before the SvmDoccatModel cast occurs. Where a usable gadget chain exists on the consuming application's classpath, this yields remote code execution in the loading JVM; OpenNLP ships no gadget itself, so realistic risk falls on downstream apps that embed the module alongside vulnerable transitive dependencies. No public exploit identified at time of analysis and the flaw is not in CISA KEV, though the SSVC assessment marks it automatable with partial technical impact.
Denial of service in Apache IoTDB versions 1.3.3 through 2.0.7 lets remote attackers crash the DataNode process by submitting a single query whose time span and aggregation interval are unbounded. Because the affected query interface enforces no reasonable limit on these parameters, a request combining a very large time range with a minimal interval forces the DataNode to materialize an enormous result set in memory, exhausting the Java heap. No public exploit has been identified at time of analysis and the issue is not in CISA KEV, but the fix is easy to reverse-engineer from the version bump to 2.0.8.
Remote code execution in the Apache Camel camel-hazelcast component allows an attacker who can join or reach the Hazelcast cluster to run arbitrary code on every Camel node. The flaw exists because Camel-created Hazelcast instances apply no Java deserialization filter by default, so crafted serialized objects sent over the cluster protocol are deserialized (ObjectInputStream.readObject) before Camel processes them. It affects Camel 4.0.0-4.14.7, 4.15.0-4.18.2, and 4.19.0-4.20.x whenever a hazelcast consumer or repository uses Camel's own default configuration; there is no public exploit identified at time of analysis and EPSS is low (0.49%, 39th percentile).
Remote code execution in Apache Camel's camel-vertx-http component (4.0.0-4.14.7, 4.15.0-4.18.2, 4.19.0) arises when a producer endpoint deserializes 5xx HTTP response bodies marked application/x-java-serialized-object through a raw java.io.ObjectInputStream with no class filtering. Exploitation is limited to non-default deployments where transferException=true or allowJavaSerializedObject=true is set and throwExceptionOnFailure remains true, letting an attacker who controls or intercepts the backend deliver a malicious serialized object and, given a gadget chain on the classpath, run code on the Camel host. This is a vendor-reported (Apache) issue with a publicly available advisory; there is no public exploit identified at time of analysis and EPSS is low at 0.39% (31st percentile).
Arbitrary file read in GravitLauncher LaunchServer ≤ 5.7.11 lets an unauthenticated remote attacker retrieve any file readable by the server process via a path-traversal in the default-enabled HTTP file server on port 9274. Because the exposed files include the ECDSA key that signs access JWTs (.keys/ecdsa_id), the refresh-token salt, and database credentials, the flaw escalates from information disclosure to a full authentication bypass allowing forged admin tokens. Publicly available exploit code exists (a raw-socket PoC in the advisory); the issue is not listed in CISA KEV and no active exploitation is confirmed.
Silent authentication downgrade in the OnGres SCRAM Java client (com.ongres.scram:scram-client and scram-common, versions <= 3.2) lets a TLS man-in-the-middle strip SCRAM-SHA-256-PLUS channel binding down to plain SCRAM-SHA-256, defeating clients that explicitly set channelBinding=require. The flaw only manifests when the server certificate uses a modern signature algorithm without a 'WITH' name (e.g., Ed25519 or post-quantum), causing the deprecated getChannelBindingData() API to swallow a NoSuchAlgorithmException and return an empty byte array that the builder misreads as 'no channel binding available.' No public exploit is identified at time of analysis, and it is not listed in CISA KEV; a vendor patch (3.3) is available.
Denial of service in OpenTelemetry Java Instrumentation before 2.27.0 lets an attacker who can reach an RMI endpoint on an instrumented JVM send an oversized context-propagation payload that triggers excessive memory allocation. The RMI payload reader caps the number of context entries but never bounds the aggregate size of the strings it reads, so a single crafted request can exhaust heap and crash or stall the JVM. No public exploit is identified at time of analysis, EPSS is low (0.24%), and CISA SSVC records no observed exploitation, but the flaw is network-reachable and unauthenticated wherever RMI instrumentation is enabled and exposed.
Insecure JNDI object instantiation in mchange-commons-java before 0.6.0 lets attackers who can influence deserialized data or JNDI Reference resolution coerce the library's JavaBeanObjectFactory into constructing arbitrary classes and setting their JavaBean properties, enabling JNDI injection and deserialization-gadget attacks. Because this library underpins mchange projects such as the c3p0 connection pool, any Java application that deserializes attacker-controlled objects or dereferences untrusted JNDI References through it is exposed; a demonstrated path abuses a Swing JEditorPane to force outbound HTTP requests from a trusted security domain. No public exploit identified at time of analysis and it is not in CISA KEV, so treat it as a patch-now supply-chain issue rather than an actively exploited one.
Unauthorized blob read, write, and delete operations in CrateDB's HTTP API allow any authenticated user to bypass privilege grants on blob tables. The HttpBlobHandler endpoint fails to enforce access control, enabling authenticated users to read, delete, or plant arbitrary blobs via crafted HTTP requests, regardless of their SQL-level permissions. Public proof-of-concept exploit code exists; a vendor patch is available, but active exploitation has not been confirmed through CISA KEV.
Arbitrary code execution in Amazon's AWS Advanced JDBC Wrapper (versions 3.3.0 through 4.0.0) arises from the RemoteQueryCachePlugin deserializing cached query results from Redis or Valkey via a raw ObjectInputStream with no class filtering. An actor able to write to the shared cache can poison entries with a crafted serialized Java object, triggering gadget-chain execution on every application server that later reads that cache entry. No public exploit identified at time of analysis; risk is elevated because a single poisoned cache key fans out to all consuming app servers.
Remote code execution in IBM WebSphere eXtreme Scale 8.6.1.0 through 8.6.1.6 arises from roughly 50 generated CORBA stub classes in the shipped ogclient.jar that invoke ORB.string_to_object() on an attacker-controlled IOR string during Java deserialization, converting any unfiltered ObjectInputStream sink in the surrounding WebSphere Application Server into outbound IIOP server-side request forgery. When chained with the IBM ORB getUserException class-instantiation flaw (tracked as WAS-26), that SSRF escalates to code execution on the calling JVM. CVSS is 10.0 (scope-changed, full CIA impact); EPSS is 3.01% (86th percentile) and there is no public exploit identified at time of analysis.
Unauthenticated remote code execution in Orkes Conductor (conductor-oss) versions 3.21.21 through 3.30.1 lets remote attackers run arbitrary OS commands by POSTing inline workflow definitions to the workflow API before any authentication check. The flaw stems from GraalVM script evaluators left in an unsandboxed state (HostAccess.ALL / allowAllAccess(true)), allowing JavaScript or Python expressions in INLINE, LAMBDA, DO_WHILE, and SWITCH tasks to reach Java reflection and subprocess APIs. Reported by VulnCheck; no public exploit identified at time of analysis, though a detailed vendor/researcher advisory exists.
Arbitrary VS Code command execution in the Red Hat vscode-java extension allows a malicious Java source file to embed hidden commands inside JavaDoc hover Markdown, so that a developer who simply clicks a crafted link in a hover popup triggers attacker-chosen commands that can escalate to full system compromise in trusted workspaces. The flaw stems from the extension rendering JavaDoc hovers as fully-trusted Markdown, and it also affects Red Hat OpenShift Dev Spaces, which bundles the extension. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the network reach combined with only a single click of user interaction makes it high-impact.
Arbitrary code execution in the OWASP ZAP ViewState add-on (versions before 4) lets a malicious or attacker-controlled proxied web server compromise the security tester's own ZAP instance. By embedding a crafted serialized Java object in the javax.faces.ViewState response parameter, an attacker triggers unsafe Java deserialization inside the ZAP JVM the moment the operator views the ViewState panel in the Desktop UI. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the vendor has published an advisory and shipped a fix (viewstate-v4) that disables JSF support entirely.
Unsafe Java deserialization in OpenAM Community Edition's Push Notification SNS callback route (through version 16.0.6) allows a low-privileged user who can start Push Registration to plant an attacker-controlled predicate blob in the CTS store, which OpenAM later loads by attacker-supplied class name and deserializes with Jackson when an anonymous SNS callback references the same messageId. The result is a reliable server-side class-loading and arbitrary-object-construction primitive that can corrupt push-token records and trigger classpath-dependent side effects such as process execution, file writes, or denial of service; the vendor explicitly states that arbitrary attacker-controlled code execution was not confirmed on stock classpaths, so real-world severity hinges on what classes are reachable in the deployment. The flaw is patched in 16.1.1 (commit ca15cba, GHSA-pp89-732f-3g8q); there is no CISA KEV listing and no public exploit code identified at time of analysis.
Authentication bypass in Apache Shiro affects deployments using the shiro-guice module in a web servlet context, where a specially crafted HTTP request can evade path-based access controls and reach protected resources without valid credentials. It mirrors the older shiro-spring flaw CVE-2020-1957 but targets the Guice integration instead, impacting all Shiro releases through 2.x and 3.0.0-alpha-1. No public exploit identified at time of analysis, though the CVSS 4.0 base score of 8.2 reflects high confidentiality impact and the close analogy to a previously exploited bug class.
Arbitrary code execution in QOS.CH logback-core versions up to and including 1.5.34 allows a local attacker with existing privilege to run code in the context of any Java application that loads Logback when the Janino library is on the classpath. The flaw circumvents prior hardening for CVE-2025-11226 via conditional configuration file processing, and is triggered either by writing to an existing logback configuration file or by injecting an environment variable that points the process at a malicious configuration. No public exploit identified at time of analysis, though the bypass nature of the issue makes weaponization of existing CVE-2025-11226 exploit code plausible.
Cross-tenant alarm destruction in OpenRemote Manager (versions before 1.25.0) allows any authenticated user with alarm-write permissions in their own realm to permanently delete alarm records belonging to other tenants by submitting arbitrary sequential alarm IDs to the bulk-delete endpoint. The flaw stems from missing per-record realm scoping in removeAlarms() and is rated CVSS 4.0 8.6 (high); no public exploit identified at time of analysis, but the GHSA advisory documents the exact vulnerable code path, making weaponization straightforward.
Remote code execution in Spring Statemachine 3.2.0-3.2.4 and 4.0.0-4.0.1 allows authenticated attackers to execute arbitrary code inside the application JVM by injecting malicious serialized Java objects into the Kryo-based persistence backends (JPA, MongoDB, Redis, or ZooKeeper). The flaw stems from deserializing persisted state-machine contexts without enforcing a class allowlist, a classic CWE-502 pattern that has historically yielded reliable gadget-chain exploitation in Java applications. No public exploit identified at time of analysis, but the deserialization sink and Kryo gadget ecosystem make weaponization straightforward once an attacker can write to the persistence store.
Unauthenticated remote code execution in Open Identity Platform's OpenDJ Community Edition (through 5.1.0) arises from Java deserialization of untrusted data in the JMX RMI connector, which reads and processes attacker-controlled bytes before authentication. Any attacker with TCP reachability to the configured JMX listener can deliver a malicious serialized object gadget chain and execute code on the directory server; the vendor demonstrated working RCE on OpenDJ 4.4.15 (JDK 11 + Jackson 2.12.6.1). No CISA KEV listing and no public exploit code identified at time of analysis, though a vendor proof-of-concept demonstration is documented in the advisory.
Remote code execution in Spinnaker's Rosco and Orca services arises because YAML input is parsed with SnakeYAML's unsafe default Constructor rather than a SafeConstructor, letting authenticated users who trigger CloudFormation deployments or CloudFoundry baking load arbitrary Java classes. An attacker with pipeline access can supply a crafted YAML tag (e.g. !!javax.script.ScriptEngineManager) to instantiate dangerous classes and reach code execution on the affected service host. No public weaponized exploit is identified, though the vendor fix commit ships tests demonstrating the arbitrary-object-instantiation primitive, and the flaw is not listed in CISA KEV.
Authentication bypass in Quarkus Java framework allows remote unauthenticated attackers to circumvent HTTP path-based authorization policies by smuggling encoded semicolons (%3B) as matrix parameters or by using encoded slashes (%2F) and backslashes (%5C) to reach protected static resources. Affects all Quarkus versions prior to the 3.37.0, 3.36.3, 3.33.2.1, 3.33.3, 3.27.4.1, 3.27.5, and 3.20.6.2 patch line. No public exploit identified at time of analysis, though the issue is a documented bypass of the prior CVE-2026-39852 fix.
Cedar policy injection in CedarJava (com.cedarpolicy:cedar-java) versions below 2.3.6, 3.4.1, and 4.9.0 allows attackers to alter authorization outcomes by smuggling Cedar expressions through unescaped string values. The flaw is in toCedarExpr() on Cedar Value types, which fails to escape quote and backslash characters when serializing user-controlled values into policy text. No public exploit identified at time of analysis, but the integrity impact is severe because injected fragments like '|| true' can neutralize permit/forbid logic in fine-grained authorization decisions.
Type confusion in CedarJava versions prior to 2.3.6, 3.4.1, and 4.9 allows authenticated remote attackers to manipulate authorization decisions by injecting reserved JSON keys (`__entity` or `__extn`) into CedarMap objects built from attacker-controlled input. When an integrating service constructs a CedarMap from caller-supplied data such as headers, metadata, or resource tags, the Rust cedar-policy evaluator can be tricked into interpreting a record as an entity reference, undermining fine-grained authorization. No public exploit identified at time of analysis, but the CVSS 8.8 rating reflects high impact on confidentiality, integrity, and availability of authorization outcomes.
Denial of service in Steeltoe.Discovery.Eureka client (.NET) versions prior to 4.2.0 and 3.4.0 allows a remote Eureka registry containing service registrations with DataCenterInfo.name="Netflix" to permanently break the local service discovery cache. The client's DataCenterInfo.FromJson rejects any value other than "MyOwn" or "Amazon" with an ArgumentException that is silently swallowed by the periodic cache refresh task, leaving downstream .NET services unable to discover peers. No public exploit identified at time of analysis, but the trigger is trivially reachable in mixed Java/Spring-Cloud and Steeltoe environments.
XML External Entity injection in the HAPI FHIR core library (Maven ca.uhn.hapi.fhir:org.hl7.fhir.utilities, versions <= 6.9.9) lets an attacker who controls or MITMs XML routed through XsltUtilities.saxonTransform(...) read local files and perform blind XXE/SSRF. The three saxonTransform overloads instantiate a bare net.sf.saxon.TransformerFactoryImpl that resolves external general and parameter entities, unlike the co-located transform() siblings that use the project's hardened XXE-protected factory. Publicly available exploit code exists (a full end-to-end PoC accompanies the GitHub advisory), though there is no public exploit identified as actively used in the wild.
Regular expression denial of service in HAPI FHIR's DSTU2 FHIRPathEngine allows unauthenticated remote attackers to exhaust server CPU by submitting FHIR resources or FHIRPath expressions containing catastrophically backtracking regexes against the matches() function. This is an incomplete-fix vulnerability stemming from CVE-2026-45367, where the DSTU2 module's matches() at FHIRPathEngine.java line 2462 was left calling raw String.matches() without the RegexTimeout wrapper applied to the other five FHIR version modules. No public exploit identified at time of analysis beyond the reporter's working PoC published in the GHSA advisory.
Arbitrary file read in jknack handlebars.java versions prior to 4.5.2 allows remote unauthenticated attackers to retrieve files outside the intended template directory when applications pass user-controlled input to Handlebars.compile() with a FileTemplateLoader or ClassPathTemplateLoader. The flaw stems from missing path canonicalization in the template loaders, enabling classic ../ traversal sequences to escape the configured template prefix. No public exploit identified at time of analysis, but the GitHub Security Advisory GHSA-r4gv-qr8j-p3pg documents the issue and the fix is available in 4.5.2.
Local denial of service in Android's PackageInstaller subsystem stems from a logic error in PackageInstallerSession.transfer() that allows a local app to trigger memory exhaustion of the system package installer. The flaw, addressed in the Android Security Bulletin for Android 17, can be triggered without user interaction and without elevated privileges, but its impact is confined to denial of service rather than code execution. No public exploit identified at time of analysis.
Origin validation failure in Spring Cloud Gateway (WebMVC and WebFlux Server variants) allows remote attackers to spoof client identity by injecting X-Forwarded-For and Forwarded headers that the gateway then forwards from untrusted proxies in certain configuration scenarios. The flaw, tracked as CVE-2026-47825 with a CVSS 3.1 base score of 8.6 (Scope:Changed, Integrity:High), affects Spring Cloud Gateway 3.1.x, 4.1.x, 4.2.x, 4.3.x, and 5.0.x. No public exploit identified at time of analysis, but the trust-boundary nature of the issue makes it an attractive target for downstream authentication and access-control bypass.
Denial-of-service in Spring Cloud Sleuth 3.1.0 through 3.1.13 allows remote unauthenticated attackers to exhaust application availability by sending specially crafted calls processed by the spring-cloud-sleuth-instrumentation library when Spring TX (transaction) instrumentation is enabled. The flaw is network-reachable with low attack complexity and no user interaction (CVSS 7.5, AV:N/AC:L/PR:N), but there is no public exploit identified at time of analysis and no CISA KEV listing. Impact is limited to availability - no confidentiality or integrity compromise is possible.
NoSQL/query injection in Spring AI Vector Stores (1.0.0-1.0.8 and 1.1.0-1.1.7) allows remote unauthenticated attackers to inject special characters into vector-store inputs and force execution of arbitrary queries against Elasticsearch, OpenSearch, and GemFire VectorDB backends. The flaw resides in the spring-ai-elasticsearch-store, spring-ai-opensearch-store, and spring-ai-gemfire-store components, enabling information disclosure and limited integrity/availability impact against any application embedding Spring AI's vector-store abstraction. No public exploit identified at time of analysis, but the CVSS 8.6 (scope unchanged here, network vector, no privileges) makes this a high-priority patch for any Spring AI deployment ingesting untrusted text.
Improper access control in File Browser (filebrowser/filebrowser, Go) versions <= 2.63.6 lets a user with share/download permissions create a public share for a path that does not yet exist; because the share record stores only a path string and is never bound to a concrete object, the link silently begins exposing whatever file later appears at that path via GET /api/public/dl/<hash>. The flaw mirrors the Android MediaProvider issue CVE-2026-0035 — the create handler omits an existence check before persisting the share. EPSS is very low (0.02%, 6th percentile) and there is no public exploit identified at time of analysis, but a step-by-step PoC is included in the GitHub Security Advisory.
Authorization bypass in Spring for GraphQL (versions 1.0.0-1.0.6, 1.3.0-1.3.8, 1.4.0-1.4.5, and 2.0.0-2.0.3) allows remote attackers to invoke @Controller data fetcher methods whose security annotations are declared on parent classes or interfaces, because the framework's annotation detection does not consistently resolve annotations across type hierarchies. The flaw is rated CVSS 7.5 (confidentiality-only impact) and no public exploit identified at time of analysis, but the network-reachable, no-privilege CVSS vector makes any affected GraphQL endpoint a meaningful exposure.
Cross-Site WebSocket Hijacking in Spring for GraphQL allows remote attackers to execute arbitrary GraphQL operations under an authenticated victim's identity when the application has enabled the GraphQL WebSocket transport. The flaw stems from missing origin validation on WebSocket handshakes (CWE-346), affecting Spring for GraphQL 1.0.x, 1.3.x, 1.4.x, and 2.0.x branches up to 2.0.3. No public exploit identified at time of analysis, but the high CVSS (8.1) and reliance only on a single victim click make this a meaningful risk for any deployment exposing the WebSocket endpoint.
Remote code execution in Spring for GraphQL versions 1.3.0-1.3.8, 1.4.0-1.4.5, and 2.0.0-2.0.3 allows unauthenticated attackers to trigger unsafe deserialization by sending crafted paginated GraphQL queries against Connection-type fields. Exploitation requires that the application expose a paginated (Connection) field and that the classpath contains gadget classes leveraged during deserialization. No public exploit identified at time of analysis; EPSS sits at 0.34% (57th percentile) and the issue is not in CISA KEV, but a vendor patch is available.
