Authentication bypass in Apache APISIX versions 2.2 through 3.16.0 allows remote attackers to circumvent authentication enforced by the jwt-auth plugin under certain configurations, granting unauthorized access to APIs that should require a valid JWT. The flaw stems from spoofable identity assertions (CWE-290) in the plugin's verification logic, and at time of analysis there is no public exploit identified, but the wide affected version range and gateway role make it operationally significant.
LDAP injection in Apache Shiro's DefaultLdapRealm allows remote unauthenticated attackers to manipulate Distinguished Name construction during LDAP bind authentication, potentially bypassing authentication or impersonating other users. The flaw affects all versions through 2.2.0 and 3.0.0-alpha-1 when DefaultLdapRealm is in use, with no public exploit identified at time of analysis. The CVSS 4.0 score of 8.8 reflects high integrity impact against an authentication-critical component.
Privilege persistence in Apache Answer through version 2.0.0 allows suspended, deleted, or deactivated administrator accounts to retain access to administrative APIs because previously issued tokens are not invalidated upon account state change. The flaw requires high-privilege access to obtain a token initially and carries a CVSS 7.2 with full confidentiality, integrity, and availability impact; no public exploit identified at time of analysis and SSVC marks exploitation as none.
Use-after-free in the mod_http2 module of Apache HTTP Server versions 2.4.55 through 2.4.67 allows remote attackers to trigger memory corruption when the server's file handle pool is exhausted. The flaw carries a CVSS 7.3 (low impact across confidentiality, integrity, and availability) and is reachable over the network without authentication or user interaction, though no public exploit identified at time of analysis. Tagging emphasizes denial-of-service and memory corruption as the primary realistic outcomes.
Denial of service in Apache HTTP Server 2.4.0 through 2.4.67 allows remote unauthenticated attackers to crash the server by submitting untrusted XML content processed by the mod_xml2enc module's xml2StartParse function. The flaw is a CWE-122 heap-based buffer overflow with a CVSS 7.5 score reflecting high availability impact only, and no public exploit has been identified at time of analysis.
Buffer over-read in Apache HTTP Server 2.4.0 through 2.4.67 allows remote attackers to trigger memory disclosure or limited integrity and availability impact via outbound OCSP requests sent to an attacker-controlled OCSP responder. The flaw stems from improper bounds handling (CWE-126) when parsing OCSP response data, and currently shows no public exploit identified at time of analysis despite a CVSS 7.3 rating reflecting unauthenticated network reachability with low complexity.
Denial of service in Apache HTTP Server 2.4.0 through 2.4.67 stems from a heap buffer overflow in the mod_proxy_html output filter, where a malicious or compromised backend can return crafted HTML that corrupts memory in the proxying httpd worker. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) reflects unauthenticated network exploitation with availability-only impact, and no public exploit was identified at time of analysis.
Apache HTTP Server 2.4.0-2.4.67 has a buffer underwrite (CWE-124) in ap_regname, triggered by a crafted regular expression in the server configuration. The vendor (Apache) rates this Low severity. A separate CISA-ADP assessment assigned CVSS 9.8 using a network, unauthenticated vector that is inconsistent with the vendor description, because exploitation requires control over the httpd configuration. No public exploit and not in CISA KEV. Fixed in 2.4.68.
Improper path handling in the mod_dav_fs module of Apache HTTP Server 2.4.67 and earlier permits a WebDAV content author to directly manipulate trusted DAV property databases, leading to integrity violations and child process crashes. With a CVSS of 9.1 (AV:N/AC:L/PR:N/UI:N) and SSVC technical impact rated 'total' with automatable=yes, the flaw is highly impactful, though there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in Apache HTTP Server versions 2.4.0 through 2.4.67 stems from a heap-based buffer overflow triggered when the server processes responses from a malicious backend while ProxyPassReverseCookieDomain or ProxyPassReverseCookiePath directives are in use. Remote attackers controlling or compromising an upstream backend can crash the front-end Apache process, impacting availability of the reverse proxy without affecting confidentiality or integrity. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Denial of service in Apache HTTP Server versions 2.4.0 through 2.4.67 stems from an infinite loop condition in the mod_proxy_ftp module when interacting with an attacker-controlled backend FTP server. Remote attackers can degrade availability and partially impact confidentiality and integrity without authentication, though exploitation requires a proxied request path to a malicious FTP backend. No public exploit identified at time of analysis, and EPSS is very low at 0.02%.
Remote code execution in Apache HTTP Server versions 2.4.0 through 2.4.67 is possible through a use-after-free condition in mod_ldap when LDAP authentication or authorization is configured in a per-directory context. The CVSS 9.8 rating reflects unauthenticated network exploitation with high impact across confidentiality, integrity, and availability, though no public exploit has been identified at time of analysis and EPSS exploitation probability remains very low at 0.02%. CISA SSVC assesses exploitation status as none but flags the issue as automatable with total technical impact.
Unsafe Java deserialization in Apache MINA's ObjectSerializationDecoder allows remote unauthenticated attackers to bypass the acceptMatchers class allow-list and achieve arbitrary code execution. Two distinct flaws are addressed: a TC_PROXYCLASSDESC handling gap where resolveProxyClass is not overridden (permitting java.lang.reflect.Proxy instantiation outside the allow-list), and a Class.forName invocation in readClassDescriptor that triggers static initializers of allow-listed classes before any instance check. No public exploit identified at time of analysis, but the CVSS 9.8 rating and well-known deserialization attack patterns make this a high-priority issue for any application exposing MINA's object serialization codec.
Code execution via Groovy sandbox bypass in Apache Syncope 3.0 through 3.0.16, 4.0 through 4.0.5, and 4.1.0 allows a high-privileged administrator holding Implementations entitlements to run untrusted code outside the sandbox. By placing payload logic in a Groovy class static initializer, the attacker reaches a non-sandboxed execution path, yielding full confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and EPSS is very low (0.02%, 6th percentile), consistent with a privilege-gated, not mass-scanned, issue.
Man-in-the-middle exposure in Apache Airflow's `apache-airflow-providers-google` package (versions prior to 22.0.0) stems from the `ComputeEngineSSHHook` shipping with `paramiko.AutoAddPolicy` as its default missing-host-key policy, silently trusting any SSH host key presented by a Compute Engine VM. An in-path network attacker positioned between the Airflow worker and the GCE instance can intercept or tamper with the SSH session, exposing credentials, DAG-driven commands, and transferred data. No public exploit identified at time of analysis and EPSS is very low (0.02%), but technical impact is rated total by SSVC.
Remote code execution in Apache CXF (versions before 3.6.11, 4.0.0-4.1.5, and 4.2.0) arises because the fix for CVE-2025-48913 was incomplete, leaving a second code path through which untrusted JMS configuration can be abused to execute code. The flaw only matters where untrusted users are permitted to supply or influence JMS transport configuration for CXF endpoints. This is a remediation-regression issue carrying no public exploit identified at time of analysis, a very low EPSS (0.10%), and SSVC exploitation status of 'none', but the technical impact is rated total.
Arbitrary certificate disclosure in Apache CXF's XKMS server lets remote attackers abuse an LDAP injection flaw (CWE-90) in the LDAP-backed certificate repository to retrieve certificates they are not authorized to see. Affected builds span Apache CXF 3.x before 3.6.11, 4.0.0-4.1.x before 4.1.6, and 4.2.0 before 4.2.1; the issue was reported by Apache itself and fixed in those releases. No public exploit identified at time of analysis, EPSS is very low (0.02%, 4th percentile), and CISA SSVC scores exploitation as 'none' with only 'partial' technical impact.
Insecure deserialization in Apache Fory's PyFory (Python) library allows remote attackers to bypass DeserializationPolicy validation hooks via the ReduceSerializer, letting untrusted classes, functions, or module attributes be restored despite policy restrictions. All PyFory releases before 1.0.0 are affected when running Python-native mode with strict mode disabled, enabling attacker-controlled data to instantiate unsafe objects and achieve code execution. There is no public exploit identified at time of analysis and EPSS probability is very low (0.04%), but CVSS is 9.8 and SSVC rates technical impact as total with automatable exploitation.
Cross-namespace privilege escalation in Apache Camel K (2.0.0-2.8.0, 2.9.0-2.9.1, 2.10.0) lets an authenticated Kubernetes user who can create Build resources dictate the target namespace for the resulting Pod, including the privileged operator namespace. By steering Pod generation into the operator's namespace, a tenant confined to their own namespace can break out of RBAC boundaries and interact with higher-privilege resources. CVSS 8.1; no public exploit identified at time of analysis and EPSS is negligible (0.02%), but SSVC rates the technical impact as total.
Privilege escalation in the Apache Airflow CNCF Kubernetes provider (versions before 10.17.0) exposes worker JWT tokens to any principal holding read-only access to Kubernetes Pods. When Airflow runs with the KubernetesExecutor, the scheduler embeds a 'workload'-scoped Execution API JWT in the pod's workload payload, so a low-privileged user who can read pod objects can harvest that token and impersonate a running task via the Task SDK, including actions that mutate Airflow database state. There is no public exploit identified at time of analysis; EPSS is 0.01% (2nd percentile) and CISA SSVC rates exploitation as none, so this is an insider/lateral-movement risk rather than a mass-exploited flaw.
Remote code execution in Apache Camel 3.18.0-4.14.5 and 4.15.0-4.18.1 stems from CXF and Knative HeaderFilterStrategy implementations filtering only outbound Camel-internal headers while leaving inbound traffic unfiltered, letting unauthenticated attackers inject control headers such as CamelExecCommandExecutable and CamelFileName through HTTP requests to CXF-RS, CXF-SOAP, or Knative HTTP endpoints. When such routes pipe into header-driven components like camel-exec or camel-file, the injected headers override configured values, yielding RCE or arbitrary file writes. No public exploit identified at time of analysis, but EPSS sits at only 0.04% despite the 9.8 CVSS - this is the fifth iteration of the same header-injection pattern (CVE-2025-27636, 2025-29891, 2025-30177, 2026-40453), so prior PoCs for sibling CVEs are likely portable.
Authenticated code injection in Apache OFBiz versions prior to 24.09.06 allows remote attackers with low-privileged accounts to execute arbitrary code via improperly neutralized directives in dynamically evaluated expressions. The flaw combines CWE-94 code injection with eval injection, yielding full confidentiality, integrity, and availability impact (CVSS 8.8). No public exploit identified at time of analysis, and EPSS rates near-term exploitation at 0.03% (8th percentile), but SSVC flags the issue as automatable, raising the risk of scripted abuse once a POC emerges.
Remote code execution in Apache OFBiz before 24.09.06 stems from an improper authentication flaw in the password-change logic that allows unauthenticated remote attackers to bypass authentication and ultimately execute arbitrary code on the server. The CVSS 9.8 rating reflects network-reachable, no-interaction exploitation against a widely deployed open-source ERP platform, though EPSS sits at only 0.07% and SSVC currently marks exploitation as 'none' - meaning no public exploit identified at time of analysis despite the severe technical impact.
LDAP injection in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to inject special characters into LDAP queries, bypassing authentication or extracting directory data with high confidentiality and integrity impact. No public exploit identified at time of analysis, and EPSS is very low (0.03%), but the CVSS 9.1 rating and CISA SSVC 'total' technical impact make it a meaningful patching priority. A vendor patch is available in version 24.09.06.
Sensitive data exposure and integrity compromise in Apache OFBiz before 24.09.06 stems from a hard-coded cryptographic key (CWE-321) shipped with the product, meaning every deployment shares the same secret. Remote unauthenticated attackers who know or extract this key from the open-source codebase can decrypt or forge protected data, undermining any cryptographic protection that relies on it. No public exploit is identified at time of analysis, and EPSS rates near-term exploitation probability very low (0.02%), but SSVC scores the technical impact as total and automatable.
Server-Side Request Forgery in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to coerce the server into issuing arbitrary outbound HTTP requests, enabling access to internal-only services, cloud metadata endpoints, and other network resources normally shielded from the internet. The CVSS 3.1 vector (7.5, C:H) reflects confidentiality-only impact, consistent with data exfiltration from internal targets rather than direct code execution. There is no public exploit identified at time of analysis, and EPSS is very low (0.02%, 4th percentile), indicating no observed exploitation activity despite the network-reachable, no-privilege attack surface.
Information disclosure in Apache OFBiz before 24.09.06 lets remote unauthenticated attackers retrieve sensitive data they should not be able to access (CWE-200). The flaw is network-reachable with low complexity and no authentication (CVSS 7.5, C:H), though no public exploit identified at time of analysis and the EPSS score is very low (0.02%). Impact is limited to confidentiality only, with no integrity or availability effect.
Server-Side Request Forgery in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to coerce the server into issuing arbitrary outbound requests through the Content component's operations. Exploitation can reach internal-only services, cloud metadata endpoints, and other network resources not otherwise accessible, with partial confidentiality, integrity, and availability impact. No public exploit has been identified at time of analysis, and EPSS exploitation probability is very low (0.02%).
Code injection in Apache Flink's SQL engine allows authenticated users to execute arbitrary code on TaskManagers through malicious SQL queries. The vulnerability affects JSON functions in versions 1.15.0+ and LIKE expressions with ESCAPE clauses in versions 1.17.0+, where user-controlled strings are interpolated into generated Java code without proper escaping. Apache has released patches in versions 1.20.4, 2.0.2, 2.1.2 and 2.2.1.
Authorization bypass in Apache Tomcat (versions 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.117, 10.1.0-M1-10.1.54, and 11.0.0-M1-11.0.21) lets remote unauthenticated attackers reach protected resources when multiple security-constraint elements define an HTTP method for the same URL extension, causing method constraints to be misapplied. Per CVSS PR:N the flaw is exploitable without authentication, yielding high confidentiality and integrity impact but no availability impact (C:H/I:H/A:N). There is no public exploit identified at time of analysis; EPSS is very low (0.02%) and CISA SSVC records exploitation status as none, though the impact is rated total and the issue is automatable.
Information disclosure in Apache Tomcat's LockOutRealm component allows remote attackers to bypass account-lockout tracking because usernames are compared with inconsistent case sensitivity (CWE-178), enabling authentication-related information leakage across Tomcat 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.117, 10.1.0-M1-10.1.54 and 11.0.0-M1-11.0.21. The CVSS 3.1 vector (7.5, C:H only) scopes the impact to confidentiality with no integrity or availability effect, consistent with the 'Information Disclosure' tagging. There is no public exploit identified at time of analysis, EPSS is negligible (0.02%, 5th percentile), and CISA SSVC records exploitation as none.
Authentication bypass in Apache Tomcat's DIGEST authentication implementation allows remote attackers to circumvent HTTP Digest access authentication and reach protected resources without valid credentials, affecting Tomcat 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.117, 10.1.0-M1-10.1.54 and 11.0.0-M1-11.0.21. The NVD-published CVSS of 9.8 reflects an unauthenticated network vector with total impact, but this record is marked DEPRECATED by the CVE program and there is no public exploit identified at time of analysis, with EPSS at just 0.04% (12th percentile) and no CISA KEV listing. Impact is scoped to deployments that actually enable DIGEST authentication, which is uncommon relative to Tomcat's overall footprint.
Improper input validation in Apache Tomcat (CWE-20) affects a broad range of releases across the 8.5, 9.0, 10.0, 10.1, and 11.0 branches, with the NVD assigning a critical CVSS 9.8 and a network/no-auth vector. No public exploit has been identified at time of analysis and the EPSS probability is only 0.04% (11th percentile), and CISA SSVC records exploitation status as none. Note a signal conflict: the intelligence tags label this 'Information Disclosure' while the official CVSS claims full confidentiality, integrity, and availability impact - the terse advisory does not resolve which is correct.
Information disclosure in Apache Tomcat versions 7.0.83 through 11.0.21 exposes HTTP authentication headers to unintended hosts during WebSocket authentication handshakes, enabling credential leakage to third-party endpoints. The flaw carries a CVSS 7.3 score with partial confidentiality, integrity, and availability impact, and no public exploit identified at time of analysis. EPSS probability is very low (0.03%) but SSVC marks the issue as automatable, indicating that scripted exploitation is feasible if attacker positioning is achieved.
Denial of service in Apache Tomcat 9.x, 10.1.x, and 11.0.x allows remote unauthenticated attackers to exhaust server resources due to missing limits or throttling on a resource allocation path (CWE-770). Affected versions span 11.0.0-M1 through 11.0.21, 10.1.0-M1 through 10.1.54, and 9.0.0.M1 through 9.0.117, with older unsupported branches also implicated per the EUVD entry. No public exploit identified at time of analysis, and the EPSS score is very low (0.02%, 5th percentile), but the SSVC framework flags the issue as automatable with partial technical impact.
Unauthorized cross-tenant access in Apache CloudStack 4.21.0 through 4.22.0 allows remote unauthenticated attackers to gain full control over virtual machines belonging to other tenants via the Proxmox extension. Attackers exploit a user-editable 'proxmox_vmid' setting that lacks tenant ownership validation and predictable VM IDs to reference and control VMs across tenant boundaries, enabling VM start/stop/destroy operations. CVSS 9.1 indicates critical severity with network attack vector and no authentication required, though EPSS data and KEV status are not available to confirm active exploitation patterns.
Remote code execution in Apache CloudStack allows authenticated account users to execute arbitrary code on KVM hypervisor hosts by registering malicious templates with unsanitized filenames. Affects CloudStack 4.11.0 through 4.20.2.0 and 4.21.0.0 through 4.22.0.0 when using KVM hypervisors. Despite high CVSS (8.8), EPSS exploitation probability is very low (0.04%, 11th percentile) and CISA SSVC reports no active exploitation. Vendor-released patches are available in versions 4.20.3.0 and 4.22.0.1.
Remote heap buffer overflow in Apache HTTP Server's mod_proxy_ajp module allows complete system compromise when proxying to attacker-controlled AJP backends. Affects all versions through 2.4.66; attackers can achieve remote code execution by sending malicious AJP protocol responses that overflow a heap buffer with 4 controlled bytes. Apache released patch in version 2.4.67. Despite critical CVSS 9.8, EPSS probability remains very low (0.02%, 5th percentile) indicating minimal observed exploitation attempts, and no CISA KEV listing confirms active in-the-wild abuse. Exploitation requires specific proxy_ajp deployment configuration connecting to malicious AJP servers.
Uncontrolled resource consumption in Apache HTTP Server's mod_md module allows remote unauthenticated attackers to exhaust server resources via malformed OCSP response data, affecting versions 2.4.30 through 2.4.66. The vulnerability enables attackers to achieve confidentiality, integrity, and availability impacts with low complexity exploitation over the network. No active exploitation confirmed (not in CISA KEV), but the network-accessible attack surface and lack of authentication requirement make this a credible threat requiring prompt patching to version 2.4.67.
XML External Entity injection in Apache OpenNLP's DictionaryEntryPersistor allows remote unauthenticated attackers to disclose local files or perform server-side request forgery when processing untrusted dictionary files. The vulnerable SAX parser initialization omits critical security features (FEATURE_SECURE_PROCESSING, DTD disablement) present elsewhere in the codebase, creating an inconsistency exploitable via the public Dictionary(InputStream) API when loading stop-word lists or domain dictionaries. With EPSS at 0.03% (8th percentile) and no active exploitation reported, this represents a code-quality issue in a specific input path rather than an imminent widespread threat, though the CVSS 9.1 reflects maximum theoretical impact given the network-accessible, unauthenticated attack vector.
Wildcard injection in Apache Polaris table names allows authenticated users to escalate privileges and access unauthorized S3 data across tables. By creating tables with literal asterisk characters (e.g., 'f*.t1', '*.*'), attackers bypass IAM policy scoping and obtain temporary S3 credentials that match other tables' storage paths. Confirmed exploitation scenarios include reading Iceberg metadata control files, listing table prefixes, and creating/deleting objects in victim tables' S3 locations - even when the attacker lacks direct Polaris permissions on those tables. Private testing confirmed this on both MinIO and AWS S3 against Polaris 1.4.0. The CVSS 9.4 (Critical) reflects network-accessible exploitation requiring only low privileges (namespace-scoped TABLE_CREATE), with high confidentiality, integrity, and availability impact across system and subsequent components. No public exploit code or CISA KEV listing identified at time of analysis, but the Apache advisory provides detailed attack mechanics.
Apache OpenNLP's model loading mechanism executes arbitrary static initializers through crafted manifest entries, enabling attackers to trigger side effects in any classpath class before type validation occurs. Affects OpenNLP versions before 2.5.9 and 3.0.0-M3. While not direct RCE, exploitation becomes viable when third-party models from untrusted sources (community repositories, model-sharing platforms) are loaded in environments containing classes with JNDI lookups, network I/O, or filesystem operations in static initializers. EPSS score of 0.29% suggests low widespread exploitation probability despite CVSS 9.8, though attack surface grows with model-sharing ecosystem adoption. No public exploit identified at time of analysis; vendor-released patches available.
Remote denial of service in Apache OpenNLP versions before 2.5.9 and 3.0.0-M3 allows unauthenticated attackers to crash JVM processes by uploading malicious .bin model files that trigger OutOfMemoryError through unbounded array allocation. Exploitation requires no authentication (AV:N/AC:L/PR:N) and affects any code path deserializing binary model files from untrusted sources. EPSS score of 0.02% (5th percentile) suggests low widespread exploitation risk, and no active exploitation or public POC has been identified at time of analysis. Vendor-released patches are available with default safeguards limiting count fields to 10 million entries.
CEL injection in Apache Polaris 1.4.0 allows authenticated users to escape credential access boundaries on Google Cloud Storage. Attackers can craft namespace or table identifiers containing single quotes and CEL fragments to break out of quoted strings in Credential Access Boundary conditions, escalating temporary table-scoped GCS credentials to effectively bucket-wide access. Confirmed in private testing: attackers obtained credentials intended for one table but successfully listed, read, created, and deleted objects across unrelated tables and external prefixes within the entire configured bucket. EPSS data not yet available for this recent CVE; CVSS 9.4 reflects critical confidentiality, integrity, and availability impact across both vulnerable and subsequent systems (scope changed).
Apache Polaris issues overly-permissive temporary storage credentials during staged table creation, allowing authenticated attackers to redirect vended credentials to attacker-controlled storage locations. The vulnerability stems from missing validation and overlap checks before credential issuance - attackers supply a custom 'location' parameter or 'write.data.path'/'write.metadata.path' properties that become effective immediately without verification. This enables unauthorized access to arbitrary storage resources beyond intended table boundaries, with CVSS 9.4 severity indicating high impact across confidentiality, integrity, and availability of both vulnerable and subsequent systems.
Authenticated attackers with table configuration privileges can bypass storage location validation in Apache Polaris by manipulating the write.metadata.path property during ALTER TABLE operations. This forces Polaris to write metadata files to attacker-controlled storage locations without proper validation, then subsequently issue cloud storage credentials for those locations. The vulnerability enables unauthorized access to and potential corruption of data belonging to other tables within the catalog's allowedLocations scope, particularly when polaris.config.allow.unstructured.table.location=true. EPSS data not available; no public exploit identified at time of analysis.
Code injection in Apache Atlas DSL search endpoint allows authenticated attackers to manipulate Gremlin traversal queries and access unauthorized data. Affects versions 0.8 through 2.4.0; exploitable in 2.0+ only when non-default configuration 'atlas.dsl.executor.traversal=false' is set. EPSS score of 0.03% (9th percentile) suggests low widespread exploitation probability. No active exploitation confirmed per CISA KEV or vendor advisory. Fixed in version 2.5.0.
Remote attackers can crash Apache HTTP Server 2.4.66 and earlier by sending malicious requests that trigger a NULL pointer dereference in mod_dav_lock, causing denial of service. The vulnerability affects only servers with mod_dav_lock enabled, a legacy module whose primary use-case (Apache Subversion < 1.2.0) is obsolete in modern deployments. CISA SSVC indicates no active exploitation, but the attack is automatable against susceptible configurations. CVSS 7.5 (High) reflects network-accessible, unauthenticated denial of service, though real-world impact is limited to the small subset of servers still running mod_dav_lock.
Remote code execution via double-free memory corruption in Apache HTTP Server 2.4.66's HTTP/2 protocol implementation allows authenticated attackers to compromise server integrity and confidentiality with high impact. Vendor-released patch 2.4.67 addresses the issue. No public exploit or active exploitation confirmed at time of analysis, but SSVC framework rates technical impact as total, indicating complete system compromise potential.
Buffer over-read in Apache HTTP Server through 2.4.66 enables remote unauthenticated information disclosure at network scale. Attackers can read sensitive memory content without authentication or user interaction, achieving high confidentiality impact with low attack complexity. EPSS exploitation probability and KEV status not provided, but SSVC framework confirms the vulnerability is automatable with partial technical impact and no active exploitation detected at time of analysis. Patch released in version 2.4.67.
Local .htaccess authors can escalate privileges to read arbitrary files as the httpd daemon user in Apache HTTP Server 2.4.66 and earlier. The vulnerability requires low-privilege authenticated access to create or modify .htaccess files, but exploits misconfigured module interactions to bypass intended access controls. Apache has released version 2.4.67 to address this issue. SSVC assessment indicates no active exploitation and non-automatable attack vector, with EPSS data not yet available for this recent disclosure.
Remote code execution in Apache MINA 2.1.0-2.1.11 and 2.2.0-2.2.6 allows unauthenticated attackers to execute arbitrary code via unsafe deserialization. The fix for prior CVE-2024-52046 was incomplete-the classname allowlist protecting IoBuffer.getObject() was applied too late, allowing malicious static initializers to execute before filtering. Confirmed actively exploited (CISA KEV). EPSS exploitation probability not provided, but the network-accessible, unauthenticated attack vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:N) combined with KEV status indicates immediate patching is critical for applications calling IoBuffer.getObject().
Remote unauthenticated code execution in Apache MINA 2.1.0-2.1.11 and 2.2.0-2.2.6 allows attackers to bypass class allowlist protections via unsafe deserialization. The vulnerability exists because the fix for CVE-2026-41635 was not backported to the 2.1.X and 2.2.X branches, leaving AbstractIoBuffer.resolveClass() susceptible to arbitrary class instantiation when applications call IoBuffer.getObject(). Only applications actively using MINA's deserialization features are affected. EPSS data not available; no KEV listing or public POC identified at time of analysis.
Algorithmic complexity denial of service in Apache Neethi allows remote unauthenticated attackers to exhaust JVM heap memory via malicious WS-Policy documents. Specially crafted policy documents trigger exponential Cartesian cross-product expansion during normalization, generating unbounded policy alternatives that consume all available memory. Apache has released version 3.2.2 with normalization limits to prevent exploitation. EPSS data not available; no CISA KEV listing identified at time of analysis.
Denial of Service in Apache Neethi WS-Policy processor allows remote unauthenticated attackers to crash applications or cause resource exhaustion by sending crafted policy documents with circular references. The vulnerability (CVSS 7.5) triggers infinite loops or stack overflow during policy normalization when Policy A references Policy B which references Policy A. Apache released version 3.2.2 to address this flaw. With network vector, low complexity, and no authentication required (AV:N/AC:L/PR:N), this represents a readily exploitable attack surface for applications parsing untrusted WS-Policy documents, though no public exploit or active exploitation (KEV) has been identified at time of analysis.
Unsafe Java deserialization in Apache Camel's camel-consul component (ConsulRegistry / ConsulRegistryUtils.deserialize) lets an attacker who can write to the backing Consul KV store achieve arbitrary code execution inside the Camel process. Any deployment using a Consul-backed Camel registry on versions 3.0.0 up to 4.14.6 or 4.15.0 up to 4.18.1 is affected. There is no public exploit identified at time of analysis, EPSS is low (0.08%), and this is a missed instance of the same deserialization class fixed in CVE-2024-22369, CVE-2024-23114 and CVE-2026-25747.
Remote code execution in Apache Camel's camel-coap component (versions 4.14.0-4.14.5, 4.18.0 before 4.18.1, and 4.19.0) allows an unauthenticated attacker to inject arbitrary internal Camel headers via CoAP URI query parameters, achieving OS command execution when a route forwards to a header-sensitive producer such as camel-exec. The component maps incoming CoAP query parameters straight into Exchange message headers with no HeaderFilterStrategy, so a single UDP packet to port 5683 can override the executable and arguments of a downstream exec producer and return command output in the CoAP response. Rated CVSS 10.0 with publicly available exploit code, though EPSS remains modest (0.55%, 68th percentile) and CISA SSVC records no observed exploitation, indicating opportunity rather than confirmed mass exploitation.
Message header injection in Apache Camel's camel-mail component (3.0.0 before 4.14.6 and 4.15.0 before 4.18.1) lets an attacker who can email a monitored mailbox smuggle Camel-prefixed MIME headers into the Exchange. Because MailHeaderFilterStrategy filters only the outbound direction and never sets an inbound filter, inbound Camel headers reach downstream components such as camel-bean, camel-exec, or camel-sql where they can alter route behavior, potentially reaching command or query execution. There is no public exploit identified at time of analysis and EPSS is very low (0.02%), but the vendor rates it CVSS 9.4 and SSVC marks it automatable.
Authentication bypass in Apache Camel's camel-platform-http-main component (versions 4.14.1–4.14.5 and 4.18.0–4.18.1) allows remote unauthenticated attackers to reach protected business routes and management endpoints when a non-root context path is configured. Because the Vert.x sub-router registers the auth handler at the exact context path rather than its subpaths, requests to paths like /api/route or /admin/observe/info evade the credential challenge, exposing runtime metadata (user, working directory, PID, JVM and OS details) via /observe/info. No public exploit identified at time of analysis; EPSS is low (0.04%) and CISA SSVC records no known exploitation, though the flaw is assessed as automatable.
Unsafe Java deserialization in Apache Camel's camel-infinispan component allows arbitrary code execution when the ProtoStream-based remote aggregation repository reads objects from an Infinispan cache using java.io.ObjectInputStream with no ObjectInputFilter applied. Any attacker able to write to the backing Infinispan cache can plant a malicious serialized gadget that executes in the application context during routine get/recover operations. Publicly available exploit code exists, though EPSS is low (0.08%) and there is no evidence of active exploitation.
Remote unauthenticated attackers can execute arbitrary code in Apache MINA 2.0.0-2.0.27, 2.1.0-2.1.10, and 2.2.0-2.2.5 through unsafe deserialization in AbstractIoBuffer.getObject(). This is an incomplete fix bypass for CVE-2024-52046 where the classname allowlist validation occurs after static initializers execute, enabling attackers to trigger malicious code execution before security controls engage. Apache confirmed the flaw affects applications calling IoBuffer.getObject() and released patches in versions 2.0.28, 2.1.11, and 2.2.6. CVSS 9.8 critical score reflects network-accessible unauthenticated exploitation with complete system compromise potential.
Remote code execution in Apache ActiveMQ allows authenticated attackers with admin console access to inject malicious Spring XML contexts that execute arbitrary code on the broker's JVM. Attackers exploit improper broker name validation to embed xbean bindings, then trigger VM transport creation via DestinationView mbean to load remote Spring XML files containing malicious bean factory methods like Runtime.exec(). EPSS score of 0.06% (19th percentile) indicates low observed exploitation probability despite CVSS 8.8, with CISA SSVC confirming no active exploitation and non-automatable attack chain. Vendor patches available: versions 5.19.6 and 6.2.5 address the vulnerability.
Remote code execution in Apache ActiveMQ 5.x (before 5.19.6) and 6.x (before 6.2.5) allows authenticated attackers to bypass prior security fixes (CVE-2026-34197) by injecting malicious Spring XML configurations through HTTP Discovery transport connectors via Jolokia. Attackers leverage a VM transport loophole to invoke arbitrary bean factory methods like Runtime.exec() during Spring context initialization. EPSS score is low (0.06%, 19th percentile) with no confirmed active exploitation (not in CISA KEV), suggesting limited widespread targeting despite high CVSS 8.8 score. Exploitation requires authenticated Jolokia access and presence of activemq-http module on classpath.
Apache HttpClient 5.6 skips mutual authentication verification in SCRAM-SHA-256 handshakes, allowing network attackers to impersonate legitimate servers without credentials. Affected clients accept unauthenticated server responses, enabling man-in-the-middle attacks that compromise confidentiality and integrity of authenticated sessions. Apache released patched version 5.6.1 addressing the missing authentication check. EPSS score of 0.03% suggests low current exploitation activity, though the network-accessible attack surface (AV:N/AC:L/PR:N) and availability of detailed vendor advisory increase exploitation risk once attackers adapt tooling for SCRAM protocol manipulation.
Apache Kafka 4.1.0 and 4.1.1 accept forged JWT tokens without signature validation, allowing remote unauthenticated attackers to authenticate as any user and gain unauthorized access to Kafka resources. The default SASL/OAUTHBEARER validator (DefaultJwtValidator) fails to verify token signatures, issuers, or audiences, enabling complete authentication bypass. CVSS 9.1 (Critical) with network vector and no privileges required. SSVC indicates the vulnerability is automatable with partial technical impact. No active exploitation confirmed at time of analysis, but the attack requires minimal sophistication and could be scripted trivially given the token acceptance behavior.
Command injection in Apache Airflow's BashOperator documentation example allows authenticated attackers to escalate privileges from UI user to worker-level code execution. Affects all Airflow versions before 3.2.0. The vulnerability stems from documentation suggesting unsafe handling of dag_run.conf parameters, which organizations may have replicated in production DAGs. EPSS score of 0.03% indicates low observed exploitation probability, though the upstream fix (PR #64129) demonstrates vendor acknowledgment and remediation.
Apache Airflow before 3.2.0 exposes SQL exception stack traces through API responses despite api/expose_stack_traces=false configuration, allowing remote unauthenticated attackers to enumerate database schema details, table names, query structure, and internal filesystem paths. CVSS 7.5 (High) with network vector and no authentication required. EPSS score of 0.02% (4th percentile) indicates low probability of widespread exploitation. Vendor patch available in Airflow 3.2.0 per Apache advisory. No active exploitation confirmed (not in CISA KEV) and no public POC identified at time of analysis.
Deserialization vulnerability in Apache Airflow webserver (all versions before 3.2.0) allows network-accessible attackers to execute arbitrary code by injecting malicious XCom payloads, despite vendor-assigned Low severity due to the trusted Dag Author threat model. CVSS 9.8 Critical rating reflects unauthenticated network-based RCE capability (AV:N/PR:N), contradicting the description's trust assumption. EPSS 0.07% (22nd percentile) suggests low immediate exploitation likelihood. No active exploitation confirmed; vendor patch available in version 3.2.0 with public GitHub PR.
Apache Airflow 3.0.x prior to 3.2.0 allows remote unauthenticated attackers to trigger unauthorized DAG (Directed Acyclic Graph) execution via the UI or API, bypassing asset materialize permission checks. Despite CVSS 7.5 HIGH, the CVSS vector (PR:N) contradicts the description's requirement for 'UI/API user with asset materialize permission', suggesting authentication IS required-a critical discrepancy that demands verification. EPSS of 0.01% (3rd percentile) indicates minimal observed exploitation activity. Vendor-released patch available in Airflow 3.2.0 per Apache advisory.
Apache Airflow 3.0.0 through 3.1.x exposes JWT authentication tokens in application logs, allowing any authenticated UI user with log access to escalate privileges and impersonate DAG Authors. CVSS rates this 7.5 HIGH for confidentiality impact, though the EPSS score of 0.02% (5th percentile) suggests minimal observed exploitation attempts. No active exploitation is confirmed; vendor patch available in version 3.2.0 released April 2026.
Unauthenticated access to Apache SkyWalking 9.7.0 to 10.3.0 allows remote attackers to retrieve sensitive MySQL/PostgreSQL configuration details through the /debugging/config/dump endpoint. No active exploitation or public exploit code is known, though the attack is trivial and automatable. The low EPSS score (0.02%) indicates minimal real-world exploitation likelihood.
Sensitive authentication tokens in Apache APISIX OpenID Connect plugin transmit in cleartext when connecting to identity providers, affecting versions 0.7 through 3.15.0. The ssl_verify parameter defaults to false, disabling TLS certificate validation and enabling potential man-in-the-middle interception of authentication credentials. With CVSS 7.5 (High), network-based attackers can intercept confidential data without authentication. EPSS probability is minimal (0.01%, 2nd percentile) with no confirmed active exploitation (CISA KEV absent), indicating theoretical risk despite high CVSS severity.
Header injection in Apache APISIX 2.12.0 through 3.15.0 lets remote attackers smuggle attacker-controlled HTTP headers through the forward-auth plugin when it is configured to relay client headers to an external authentication service. Because injected headers can spoof identity or authorization data trusted by the upstream auth endpoint, this can lead to authentication bypass or privilege escalation. There is no public exploit identified at time of analysis and EPSS is very low (0.03%), but CISA's SSVC framework rates the technical impact as total and the attack as automatable.
Remote code execution in Apache Airflow 3.1.x allows authenticated DAG Authors to execute arbitrary code in the webserver context through crafted XCom payloads exploiting insecure deserialization (CWE-502). Affects Apache Airflow versions 3.1.8 through <3.2.0. Despite CVSS 8.8, vendor rates severity as Low due to DAG Authors being highly trusted roles. No public exploit identified at time of analysis, with EPSS exploitation probability at 0.07% (21st percentile), indicating minimal real-world risk. Vendor-released patch: Apache Airflow 3.2.0.
Server-Side Request Forgery in Apache SkyWalking MCP 0.1.0 allows authenticated remote attackers to access internal network resources and exfiltrate sensitive data via a malicious SW-URL header. CVSS 7.1 (High severity) with network attack vector and low complexity. No public exploit identified at time of analysis, SSVC framework indicates no active exploitation and non-automatable attack requiring manual interaction with internal architecture knowledge.
Remote code execution in Apache Storm before 2.8.6 allows authenticated users with topology submission rights to execute arbitrary code on Nimbus and Worker JVMs via crafted serialized objects in Kerberos TGT credentials. The vulnerability exploits unsafe deserialization in the Nimbus Thrift API (CWE-502) with CVSS 8.8. No active exploitation confirmed (EPSS 0.30%, SSVC exploitation status: none), but the low attack complexity and network attack vector make this a critical patch priority for Storm deployments with authenticated users.
Out-of-memory denial of service in Apache ActiveMQ allows unauthenticated remote attackers to exhaust broker memory via rapid TLSv1.3 KeyUpdate requests. Affects ActiveMQ Client, Broker, and All distributions versions <5.19.4 and 6.0.0-6.2.3 when NIO SSL transports are used. Vulnerability arises from improper handling of TLSv1.3 handshake KeyUpdate messages, enabling clients to trigger unbounded memory allocation in the SSL engine. No public exploit identified at time of analysis. CVSS 7.5 (AV:N/AC:L/PR:N) indicates network-accessible, low-complexity attack requiring no authentication.
Apache Tomcat's cloud membership clustering component logs Kubernetes bearer tokens in plaintext, enabling unauthenticated remote attackers to extract authentication credentials from log files. Affects Tomcat 9.0.13-9.0.116, 10.1.0-M1-10.1.53, and 11.0.0-M1-11.0.20. CVSS 7.5 (High) reflects confidentiality impact; no public exploit identified at time of analysis. Exploitation requires network access to log files or log aggregation systems, potentially enabling privilege escalation within Kubernetes clusters.
Missing encryption of cluster replication traffic in Apache Tomcat 11.0.20, 10.1.53, and 9.0.116 exposes sensitive session data to network-positioned attackers because the EncryptInterceptor - the clustering security control - can be bypassed due to a regression introduced by the fix for CVE-2026-29146. Listed in CISA KEV as actively exploited with a publicly available exploit, though EPSS sits at just 0.01% (1st percentile), indicating targeted rather than widespread automated exploitation. The confidentiality impact is rated High with no integrity or availability impact, consistent with CWE-311 (Missing Encryption of Sensitive Data).
Information disclosure in Apache Tomcat's JsonAccessLogValve allows unauthenticated remote attackers to retrieve sensitive data due to improper output encoding. Affects Tomcat versions 11.0.0-M1 through 11.0.20, 10.1.0-M1 through 10.1.53, and 9.0.40 through 9.0.116. The vulnerability enables high-impact confidentiality breaches through network-accessible attack vectors with low complexity and no user interaction required. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.02%).
Padding oracle attack in Apache Tomcat EncryptInterceptor leaks encrypted session data confidentiality across versions 7.0.100-7.0.109, 8.5.38-8.5.100, 9.0.13-9.0.115, 10.0.0-M1-10.1.52, and 11.0.0-M1-11.0.18 when default configuration is deployed. Unauthenticated remote attackers exploit oracle responses to decrypt sensitive information without authentication (CVSS:3.1 AV:N/AC:L/PR:N). CWE-209 (information exposure through error messages) enables cryptographic side-channel extraction. No public exploit identified at time of analysis; low observed exploitation activity (EPSS 0.02%).
Authentication bypass in Apache Tomcat 9.x through 11.x and Tomcat Native 1.1.23-2.0.13 allows unauthenticated remote attackers to bypass CLIENT_CERT authentication when soft-fail is disabled, achieving unauthorized access to confidentiality- and integrity-sensitive resources. Exploitation requires no user interaction or privileges (CVSS:3.1 PR:N/UI:N). The flaw affects CLIENT_CERT authentication logic, permitting access under conditions where authentication should fail. No public exploit identified at time of analysis; low observed exploitation activity (EPSS 0.04%).
Cipher preference order enforcement failure in Apache Tomcat 9.0.114-9.0.115, 10.1.51-10.1.52, and 11.0.16-11.0.18 allows unauthenticated remote attackers to force selection of weaker cryptographic ciphers during TLS negotiation, enabling potential decryption of confidential data transmitted over HTTPS connections. The vulnerability stems from improper preservation of administrator-configured cipher suite priority, potentially exposing sensitive session data, credentials, or application content. No public exploit identified at time of analysis. CVSS 7.5 (High) reflects network-accessible confidentiality impact requiring no privileges.
HTTP request smuggling in Apache Tomcat 7.x through 11.x permits unauthenticated remote attackers to manipulate request routing and bypass security controls via malformed chunk extension processing. Exploitation enables header injection, cache poisoning, and request routing manipulation without code execution. Affects Tomcat 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.115, 10.1.0-M1-10.1.52, and 11.0.0-M1-11.0.18. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.02%).
Remote denial-of-service in Apache ActiveMQ 6.0.0 through 6.2.3 allows unauthenticated network attackers to crash the MQTT broker via malformed control packets. An integer overflow in the MQTT protocol handler's remaining length field validation enables resource exhaustion without authentication. This vulnerability stems from an incomplete patch - the fix for CVE-2025-66168 was applied only to 5.19.x branches but omitted from all 6.x releases until 6.2.4. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.02%).
Hard-coded cryptographic key in Apache OpenMeetings 6.1.0-9.0.0 enables cookie-based credential theft. The default remember-me cookie encryption key in openmeetings.properties is not auto-rotated, allowing attackers who steal session cookies to decrypt and extract full user credentials without authentication. This unauthenticated network-accessible vulnerability achieves high confidentiality impact through cryptographic weakness. No public exploit identified at time of analysis. EPSS indicates low observed exploitation activity.
Apache OpenMeetings REST login endpoint exposes credentials through HTTP GET query parameters, enabling credential harvesting via browser history, server logs, referrer headers, and intermediate proxies. Affects versions 3.1.3 through 8.x. CVSS 7.5 HIGH reflects unauthenticated network-accessible information disclosure with no user interaction required. No public exploit identified at time of analysis, low observed exploitation activity (EPSS 0.02%).
Apache Cassandra 5.0 through 5.0.6 in mTLS environments using MutualTlsAuthenticator allows authenticated users with only CREATE permission to escalate privileges to superuser via certificate identity manipulation through the ADD IDENTITY command. CVSS 8.8 reflects high impact across confidentiality, integrity, and availability. No public exploit identified at time of analysis, with SSVC indicating non-automatable exploitation but total technical impact. Apache released patch version 5.0.7+ addressing this privilege escalation flaw (CWE-267: Privilege Defined With Unsafe Actions).
Buffer use-after-free in Apache Kafka Java producer client (versions ≤3.9.1, ≤4.0.1, ≤4.1.1) can silently route messages to incorrect topics when batch expiration races with in-flight network requests. CVSS 8.7 (High) with network-accessible attack vector and high complexity. CISA SSVC indicates no active exploitation, non-automatable attack, and partial technical impact. No public exploit identified at time of analysis. EPSS data not provided, but the combination of high CVSS, cross-scope impact (S:C), and dual confidentiality/integrity impact warrants prioritization for environments processing sensitive message streams.
Remote code execution in Apache ActiveMQ Classic versions before 5.19.5 and 6.0.0-6.2.2 allows authenticated attackers to execute arbitrary code on the broker's JVM via Jolokia MBean operations. Attackers with low-privilege web console access can invoke BrokerService.addNetworkConnector() with a malicious discovery URI containing a VM transport brokerConfig parameter that loads remote Spring XML contexts, triggering bean instantiation and code execution through factory methods like Runtime.exec(
Authentication bypass in Apache APISIX versions 2.2 through 3.16.0 allows remote attackers to circumvent authentication enforced by the jwt-auth plugin under certain configurations, granting unauthorized access to APIs that should require a valid JWT. The flaw stems from spoofable identity assertions (CWE-290) in the plugin's verification logic, and at time of analysis there is no public exploit identified, but the wide affected version range and gateway role make it operationally significant.
LDAP injection in Apache Shiro's DefaultLdapRealm allows remote unauthenticated attackers to manipulate Distinguished Name construction during LDAP bind authentication, potentially bypassing authentication or impersonating other users. The flaw affects all versions through 2.2.0 and 3.0.0-alpha-1 when DefaultLdapRealm is in use, with no public exploit identified at time of analysis. The CVSS 4.0 score of 8.8 reflects high integrity impact against an authentication-critical component.
Privilege persistence in Apache Answer through version 2.0.0 allows suspended, deleted, or deactivated administrator accounts to retain access to administrative APIs because previously issued tokens are not invalidated upon account state change. The flaw requires high-privilege access to obtain a token initially and carries a CVSS 7.2 with full confidentiality, integrity, and availability impact; no public exploit identified at time of analysis and SSVC marks exploitation as none.
Use-after-free in the mod_http2 module of Apache HTTP Server versions 2.4.55 through 2.4.67 allows remote attackers to trigger memory corruption when the server's file handle pool is exhausted. The flaw carries a CVSS 7.3 (low impact across confidentiality, integrity, and availability) and is reachable over the network without authentication or user interaction, though no public exploit identified at time of analysis. Tagging emphasizes denial-of-service and memory corruption as the primary realistic outcomes.
Denial of service in Apache HTTP Server 2.4.0 through 2.4.67 allows remote unauthenticated attackers to crash the server by submitting untrusted XML content processed by the mod_xml2enc module's xml2StartParse function. The flaw is a CWE-122 heap-based buffer overflow with a CVSS 7.5 score reflecting high availability impact only, and no public exploit has been identified at time of analysis.
Buffer over-read in Apache HTTP Server 2.4.0 through 2.4.67 allows remote attackers to trigger memory disclosure or limited integrity and availability impact via outbound OCSP requests sent to an attacker-controlled OCSP responder. The flaw stems from improper bounds handling (CWE-126) when parsing OCSP response data, and currently shows no public exploit identified at time of analysis despite a CVSS 7.3 rating reflecting unauthenticated network reachability with low complexity.
Denial of service in Apache HTTP Server 2.4.0 through 2.4.67 stems from a heap buffer overflow in the mod_proxy_html output filter, where a malicious or compromised backend can return crafted HTML that corrupts memory in the proxying httpd worker. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) reflects unauthenticated network exploitation with availability-only impact, and no public exploit was identified at time of analysis.
Apache HTTP Server 2.4.0-2.4.67 has a buffer underwrite (CWE-124) in ap_regname, triggered by a crafted regular expression in the server configuration. The vendor (Apache) rates this Low severity. A separate CISA-ADP assessment assigned CVSS 9.8 using a network, unauthenticated vector that is inconsistent with the vendor description, because exploitation requires control over the httpd configuration. No public exploit and not in CISA KEV. Fixed in 2.4.68.
Improper path handling in the mod_dav_fs module of Apache HTTP Server 2.4.67 and earlier permits a WebDAV content author to directly manipulate trusted DAV property databases, leading to integrity violations and child process crashes. With a CVSS of 9.1 (AV:N/AC:L/PR:N/UI:N) and SSVC technical impact rated 'total' with automatable=yes, the flaw is highly impactful, though there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in Apache HTTP Server versions 2.4.0 through 2.4.67 stems from a heap-based buffer overflow triggered when the server processes responses from a malicious backend while ProxyPassReverseCookieDomain or ProxyPassReverseCookiePath directives are in use. Remote attackers controlling or compromising an upstream backend can crash the front-end Apache process, impacting availability of the reverse proxy without affecting confidentiality or integrity. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Denial of service in Apache HTTP Server versions 2.4.0 through 2.4.67 stems from an infinite loop condition in the mod_proxy_ftp module when interacting with an attacker-controlled backend FTP server. Remote attackers can degrade availability and partially impact confidentiality and integrity without authentication, though exploitation requires a proxied request path to a malicious FTP backend. No public exploit identified at time of analysis, and EPSS is very low at 0.02%.
Remote code execution in Apache HTTP Server versions 2.4.0 through 2.4.67 is possible through a use-after-free condition in mod_ldap when LDAP authentication or authorization is configured in a per-directory context. The CVSS 9.8 rating reflects unauthenticated network exploitation with high impact across confidentiality, integrity, and availability, though no public exploit has been identified at time of analysis and EPSS exploitation probability remains very low at 0.02%. CISA SSVC assesses exploitation status as none but flags the issue as automatable with total technical impact.
Unsafe Java deserialization in Apache MINA's ObjectSerializationDecoder allows remote unauthenticated attackers to bypass the acceptMatchers class allow-list and achieve arbitrary code execution. Two distinct flaws are addressed: a TC_PROXYCLASSDESC handling gap where resolveProxyClass is not overridden (permitting java.lang.reflect.Proxy instantiation outside the allow-list), and a Class.forName invocation in readClassDescriptor that triggers static initializers of allow-listed classes before any instance check. No public exploit identified at time of analysis, but the CVSS 9.8 rating and well-known deserialization attack patterns make this a high-priority issue for any application exposing MINA's object serialization codec.
Code execution via Groovy sandbox bypass in Apache Syncope 3.0 through 3.0.16, 4.0 through 4.0.5, and 4.1.0 allows a high-privileged administrator holding Implementations entitlements to run untrusted code outside the sandbox. By placing payload logic in a Groovy class static initializer, the attacker reaches a non-sandboxed execution path, yielding full confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and EPSS is very low (0.02%, 6th percentile), consistent with a privilege-gated, not mass-scanned, issue.
Man-in-the-middle exposure in Apache Airflow's `apache-airflow-providers-google` package (versions prior to 22.0.0) stems from the `ComputeEngineSSHHook` shipping with `paramiko.AutoAddPolicy` as its default missing-host-key policy, silently trusting any SSH host key presented by a Compute Engine VM. An in-path network attacker positioned between the Airflow worker and the GCE instance can intercept or tamper with the SSH session, exposing credentials, DAG-driven commands, and transferred data. No public exploit identified at time of analysis and EPSS is very low (0.02%), but technical impact is rated total by SSVC.
Remote code execution in Apache CXF (versions before 3.6.11, 4.0.0-4.1.5, and 4.2.0) arises because the fix for CVE-2025-48913 was incomplete, leaving a second code path through which untrusted JMS configuration can be abused to execute code. The flaw only matters where untrusted users are permitted to supply or influence JMS transport configuration for CXF endpoints. This is a remediation-regression issue carrying no public exploit identified at time of analysis, a very low EPSS (0.10%), and SSVC exploitation status of 'none', but the technical impact is rated total.
Arbitrary certificate disclosure in Apache CXF's XKMS server lets remote attackers abuse an LDAP injection flaw (CWE-90) in the LDAP-backed certificate repository to retrieve certificates they are not authorized to see. Affected builds span Apache CXF 3.x before 3.6.11, 4.0.0-4.1.x before 4.1.6, and 4.2.0 before 4.2.1; the issue was reported by Apache itself and fixed in those releases. No public exploit identified at time of analysis, EPSS is very low (0.02%, 4th percentile), and CISA SSVC scores exploitation as 'none' with only 'partial' technical impact.
Insecure deserialization in Apache Fory's PyFory (Python) library allows remote attackers to bypass DeserializationPolicy validation hooks via the ReduceSerializer, letting untrusted classes, functions, or module attributes be restored despite policy restrictions. All PyFory releases before 1.0.0 are affected when running Python-native mode with strict mode disabled, enabling attacker-controlled data to instantiate unsafe objects and achieve code execution. There is no public exploit identified at time of analysis and EPSS probability is very low (0.04%), but CVSS is 9.8 and SSVC rates technical impact as total with automatable exploitation.
Cross-namespace privilege escalation in Apache Camel K (2.0.0-2.8.0, 2.9.0-2.9.1, 2.10.0) lets an authenticated Kubernetes user who can create Build resources dictate the target namespace for the resulting Pod, including the privileged operator namespace. By steering Pod generation into the operator's namespace, a tenant confined to their own namespace can break out of RBAC boundaries and interact with higher-privilege resources. CVSS 8.1; no public exploit identified at time of analysis and EPSS is negligible (0.02%), but SSVC rates the technical impact as total.
Privilege escalation in the Apache Airflow CNCF Kubernetes provider (versions before 10.17.0) exposes worker JWT tokens to any principal holding read-only access to Kubernetes Pods. When Airflow runs with the KubernetesExecutor, the scheduler embeds a 'workload'-scoped Execution API JWT in the pod's workload payload, so a low-privileged user who can read pod objects can harvest that token and impersonate a running task via the Task SDK, including actions that mutate Airflow database state. There is no public exploit identified at time of analysis; EPSS is 0.01% (2nd percentile) and CISA SSVC rates exploitation as none, so this is an insider/lateral-movement risk rather than a mass-exploited flaw.
Remote code execution in Apache Camel 3.18.0-4.14.5 and 4.15.0-4.18.1 stems from CXF and Knative HeaderFilterStrategy implementations filtering only outbound Camel-internal headers while leaving inbound traffic unfiltered, letting unauthenticated attackers inject control headers such as CamelExecCommandExecutable and CamelFileName through HTTP requests to CXF-RS, CXF-SOAP, or Knative HTTP endpoints. When such routes pipe into header-driven components like camel-exec or camel-file, the injected headers override configured values, yielding RCE or arbitrary file writes. No public exploit identified at time of analysis, but EPSS sits at only 0.04% despite the 9.8 CVSS - this is the fifth iteration of the same header-injection pattern (CVE-2025-27636, 2025-29891, 2025-30177, 2026-40453), so prior PoCs for sibling CVEs are likely portable.
Authenticated code injection in Apache OFBiz versions prior to 24.09.06 allows remote attackers with low-privileged accounts to execute arbitrary code via improperly neutralized directives in dynamically evaluated expressions. The flaw combines CWE-94 code injection with eval injection, yielding full confidentiality, integrity, and availability impact (CVSS 8.8). No public exploit identified at time of analysis, and EPSS rates near-term exploitation at 0.03% (8th percentile), but SSVC flags the issue as automatable, raising the risk of scripted abuse once a POC emerges.
Remote code execution in Apache OFBiz before 24.09.06 stems from an improper authentication flaw in the password-change logic that allows unauthenticated remote attackers to bypass authentication and ultimately execute arbitrary code on the server. The CVSS 9.8 rating reflects network-reachable, no-interaction exploitation against a widely deployed open-source ERP platform, though EPSS sits at only 0.07% and SSVC currently marks exploitation as 'none' - meaning no public exploit identified at time of analysis despite the severe technical impact.
LDAP injection in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to inject special characters into LDAP queries, bypassing authentication or extracting directory data with high confidentiality and integrity impact. No public exploit identified at time of analysis, and EPSS is very low (0.03%), but the CVSS 9.1 rating and CISA SSVC 'total' technical impact make it a meaningful patching priority. A vendor patch is available in version 24.09.06.
Sensitive data exposure and integrity compromise in Apache OFBiz before 24.09.06 stems from a hard-coded cryptographic key (CWE-321) shipped with the product, meaning every deployment shares the same secret. Remote unauthenticated attackers who know or extract this key from the open-source codebase can decrypt or forge protected data, undermining any cryptographic protection that relies on it. No public exploit is identified at time of analysis, and EPSS rates near-term exploitation probability very low (0.02%), but SSVC scores the technical impact as total and automatable.
Server-Side Request Forgery in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to coerce the server into issuing arbitrary outbound HTTP requests, enabling access to internal-only services, cloud metadata endpoints, and other network resources normally shielded from the internet. The CVSS 3.1 vector (7.5, C:H) reflects confidentiality-only impact, consistent with data exfiltration from internal targets rather than direct code execution. There is no public exploit identified at time of analysis, and EPSS is very low (0.02%, 4th percentile), indicating no observed exploitation activity despite the network-reachable, no-privilege attack surface.
Information disclosure in Apache OFBiz before 24.09.06 lets remote unauthenticated attackers retrieve sensitive data they should not be able to access (CWE-200). The flaw is network-reachable with low complexity and no authentication (CVSS 7.5, C:H), though no public exploit identified at time of analysis and the EPSS score is very low (0.02%). Impact is limited to confidentiality only, with no integrity or availability effect.
Server-Side Request Forgery in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to coerce the server into issuing arbitrary outbound requests through the Content component's operations. Exploitation can reach internal-only services, cloud metadata endpoints, and other network resources not otherwise accessible, with partial confidentiality, integrity, and availability impact. No public exploit has been identified at time of analysis, and EPSS exploitation probability is very low (0.02%).
Code injection in Apache Flink's SQL engine allows authenticated users to execute arbitrary code on TaskManagers through malicious SQL queries. The vulnerability affects JSON functions in versions 1.15.0+ and LIKE expressions with ESCAPE clauses in versions 1.17.0+, where user-controlled strings are interpolated into generated Java code without proper escaping. Apache has released patches in versions 1.20.4, 2.0.2, 2.1.2 and 2.2.1.
Authorization bypass in Apache Tomcat (versions 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.117, 10.1.0-M1-10.1.54, and 11.0.0-M1-11.0.21) lets remote unauthenticated attackers reach protected resources when multiple security-constraint elements define an HTTP method for the same URL extension, causing method constraints to be misapplied. Per CVSS PR:N the flaw is exploitable without authentication, yielding high confidentiality and integrity impact but no availability impact (C:H/I:H/A:N). There is no public exploit identified at time of analysis; EPSS is very low (0.02%) and CISA SSVC records exploitation status as none, though the impact is rated total and the issue is automatable.
Information disclosure in Apache Tomcat's LockOutRealm component allows remote attackers to bypass account-lockout tracking because usernames are compared with inconsistent case sensitivity (CWE-178), enabling authentication-related information leakage across Tomcat 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.117, 10.1.0-M1-10.1.54 and 11.0.0-M1-11.0.21. The CVSS 3.1 vector (7.5, C:H only) scopes the impact to confidentiality with no integrity or availability effect, consistent with the 'Information Disclosure' tagging. There is no public exploit identified at time of analysis, EPSS is negligible (0.02%, 5th percentile), and CISA SSVC records exploitation as none.
Authentication bypass in Apache Tomcat's DIGEST authentication implementation allows remote attackers to circumvent HTTP Digest access authentication and reach protected resources without valid credentials, affecting Tomcat 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.117, 10.1.0-M1-10.1.54 and 11.0.0-M1-11.0.21. The NVD-published CVSS of 9.8 reflects an unauthenticated network vector with total impact, but this record is marked DEPRECATED by the CVE program and there is no public exploit identified at time of analysis, with EPSS at just 0.04% (12th percentile) and no CISA KEV listing. Impact is scoped to deployments that actually enable DIGEST authentication, which is uncommon relative to Tomcat's overall footprint.
Improper input validation in Apache Tomcat (CWE-20) affects a broad range of releases across the 8.5, 9.0, 10.0, 10.1, and 11.0 branches, with the NVD assigning a critical CVSS 9.8 and a network/no-auth vector. No public exploit has been identified at time of analysis and the EPSS probability is only 0.04% (11th percentile), and CISA SSVC records exploitation status as none. Note a signal conflict: the intelligence tags label this 'Information Disclosure' while the official CVSS claims full confidentiality, integrity, and availability impact - the terse advisory does not resolve which is correct.
Information disclosure in Apache Tomcat versions 7.0.83 through 11.0.21 exposes HTTP authentication headers to unintended hosts during WebSocket authentication handshakes, enabling credential leakage to third-party endpoints. The flaw carries a CVSS 7.3 score with partial confidentiality, integrity, and availability impact, and no public exploit identified at time of analysis. EPSS probability is very low (0.03%) but SSVC marks the issue as automatable, indicating that scripted exploitation is feasible if attacker positioning is achieved.
Denial of service in Apache Tomcat 9.x, 10.1.x, and 11.0.x allows remote unauthenticated attackers to exhaust server resources due to missing limits or throttling on a resource allocation path (CWE-770). Affected versions span 11.0.0-M1 through 11.0.21, 10.1.0-M1 through 10.1.54, and 9.0.0.M1 through 9.0.117, with older unsupported branches also implicated per the EUVD entry. No public exploit identified at time of analysis, and the EPSS score is very low (0.02%, 5th percentile), but the SSVC framework flags the issue as automatable with partial technical impact.
Unauthorized cross-tenant access in Apache CloudStack 4.21.0 through 4.22.0 allows remote unauthenticated attackers to gain full control over virtual machines belonging to other tenants via the Proxmox extension. Attackers exploit a user-editable 'proxmox_vmid' setting that lacks tenant ownership validation and predictable VM IDs to reference and control VMs across tenant boundaries, enabling VM start/stop/destroy operations. CVSS 9.1 indicates critical severity with network attack vector and no authentication required, though EPSS data and KEV status are not available to confirm active exploitation patterns.
Remote code execution in Apache CloudStack allows authenticated account users to execute arbitrary code on KVM hypervisor hosts by registering malicious templates with unsanitized filenames. Affects CloudStack 4.11.0 through 4.20.2.0 and 4.21.0.0 through 4.22.0.0 when using KVM hypervisors. Despite high CVSS (8.8), EPSS exploitation probability is very low (0.04%, 11th percentile) and CISA SSVC reports no active exploitation. Vendor-released patches are available in versions 4.20.3.0 and 4.22.0.1.
Remote heap buffer overflow in Apache HTTP Server's mod_proxy_ajp module allows complete system compromise when proxying to attacker-controlled AJP backends. Affects all versions through 2.4.66; attackers can achieve remote code execution by sending malicious AJP protocol responses that overflow a heap buffer with 4 controlled bytes. Apache released patch in version 2.4.67. Despite critical CVSS 9.8, EPSS probability remains very low (0.02%, 5th percentile) indicating minimal observed exploitation attempts, and no CISA KEV listing confirms active in-the-wild abuse. Exploitation requires specific proxy_ajp deployment configuration connecting to malicious AJP servers.
Uncontrolled resource consumption in Apache HTTP Server's mod_md module allows remote unauthenticated attackers to exhaust server resources via malformed OCSP response data, affecting versions 2.4.30 through 2.4.66. The vulnerability enables attackers to achieve confidentiality, integrity, and availability impacts with low complexity exploitation over the network. No active exploitation confirmed (not in CISA KEV), but the network-accessible attack surface and lack of authentication requirement make this a credible threat requiring prompt patching to version 2.4.67.
XML External Entity injection in Apache OpenNLP's DictionaryEntryPersistor allows remote unauthenticated attackers to disclose local files or perform server-side request forgery when processing untrusted dictionary files. The vulnerable SAX parser initialization omits critical security features (FEATURE_SECURE_PROCESSING, DTD disablement) present elsewhere in the codebase, creating an inconsistency exploitable via the public Dictionary(InputStream) API when loading stop-word lists or domain dictionaries. With EPSS at 0.03% (8th percentile) and no active exploitation reported, this represents a code-quality issue in a specific input path rather than an imminent widespread threat, though the CVSS 9.1 reflects maximum theoretical impact given the network-accessible, unauthenticated attack vector.
Wildcard injection in Apache Polaris table names allows authenticated users to escalate privileges and access unauthorized S3 data across tables. By creating tables with literal asterisk characters (e.g., 'f*.t1', '*.*'), attackers bypass IAM policy scoping and obtain temporary S3 credentials that match other tables' storage paths. Confirmed exploitation scenarios include reading Iceberg metadata control files, listing table prefixes, and creating/deleting objects in victim tables' S3 locations - even when the attacker lacks direct Polaris permissions on those tables. Private testing confirmed this on both MinIO and AWS S3 against Polaris 1.4.0. The CVSS 9.4 (Critical) reflects network-accessible exploitation requiring only low privileges (namespace-scoped TABLE_CREATE), with high confidentiality, integrity, and availability impact across system and subsequent components. No public exploit code or CISA KEV listing identified at time of analysis, but the Apache advisory provides detailed attack mechanics.
Apache OpenNLP's model loading mechanism executes arbitrary static initializers through crafted manifest entries, enabling attackers to trigger side effects in any classpath class before type validation occurs. Affects OpenNLP versions before 2.5.9 and 3.0.0-M3. While not direct RCE, exploitation becomes viable when third-party models from untrusted sources (community repositories, model-sharing platforms) are loaded in environments containing classes with JNDI lookups, network I/O, or filesystem operations in static initializers. EPSS score of 0.29% suggests low widespread exploitation probability despite CVSS 9.8, though attack surface grows with model-sharing ecosystem adoption. No public exploit identified at time of analysis; vendor-released patches available.
Remote denial of service in Apache OpenNLP versions before 2.5.9 and 3.0.0-M3 allows unauthenticated attackers to crash JVM processes by uploading malicious .bin model files that trigger OutOfMemoryError through unbounded array allocation. Exploitation requires no authentication (AV:N/AC:L/PR:N) and affects any code path deserializing binary model files from untrusted sources. EPSS score of 0.02% (5th percentile) suggests low widespread exploitation risk, and no active exploitation or public POC has been identified at time of analysis. Vendor-released patches are available with default safeguards limiting count fields to 10 million entries.
CEL injection in Apache Polaris 1.4.0 allows authenticated users to escape credential access boundaries on Google Cloud Storage. Attackers can craft namespace or table identifiers containing single quotes and CEL fragments to break out of quoted strings in Credential Access Boundary conditions, escalating temporary table-scoped GCS credentials to effectively bucket-wide access. Confirmed in private testing: attackers obtained credentials intended for one table but successfully listed, read, created, and deleted objects across unrelated tables and external prefixes within the entire configured bucket. EPSS data not yet available for this recent CVE; CVSS 9.4 reflects critical confidentiality, integrity, and availability impact across both vulnerable and subsequent systems (scope changed).
Apache Polaris issues overly-permissive temporary storage credentials during staged table creation, allowing authenticated attackers to redirect vended credentials to attacker-controlled storage locations. The vulnerability stems from missing validation and overlap checks before credential issuance - attackers supply a custom 'location' parameter or 'write.data.path'/'write.metadata.path' properties that become effective immediately without verification. This enables unauthorized access to arbitrary storage resources beyond intended table boundaries, with CVSS 9.4 severity indicating high impact across confidentiality, integrity, and availability of both vulnerable and subsequent systems.
Authenticated attackers with table configuration privileges can bypass storage location validation in Apache Polaris by manipulating the write.metadata.path property during ALTER TABLE operations. This forces Polaris to write metadata files to attacker-controlled storage locations without proper validation, then subsequently issue cloud storage credentials for those locations. The vulnerability enables unauthorized access to and potential corruption of data belonging to other tables within the catalog's allowedLocations scope, particularly when polaris.config.allow.unstructured.table.location=true. EPSS data not available; no public exploit identified at time of analysis.
Code injection in Apache Atlas DSL search endpoint allows authenticated attackers to manipulate Gremlin traversal queries and access unauthorized data. Affects versions 0.8 through 2.4.0; exploitable in 2.0+ only when non-default configuration 'atlas.dsl.executor.traversal=false' is set. EPSS score of 0.03% (9th percentile) suggests low widespread exploitation probability. No active exploitation confirmed per CISA KEV or vendor advisory. Fixed in version 2.5.0.
Remote attackers can crash Apache HTTP Server 2.4.66 and earlier by sending malicious requests that trigger a NULL pointer dereference in mod_dav_lock, causing denial of service. The vulnerability affects only servers with mod_dav_lock enabled, a legacy module whose primary use-case (Apache Subversion < 1.2.0) is obsolete in modern deployments. CISA SSVC indicates no active exploitation, but the attack is automatable against susceptible configurations. CVSS 7.5 (High) reflects network-accessible, unauthenticated denial of service, though real-world impact is limited to the small subset of servers still running mod_dav_lock.
Remote code execution via double-free memory corruption in Apache HTTP Server 2.4.66's HTTP/2 protocol implementation allows authenticated attackers to compromise server integrity and confidentiality with high impact. Vendor-released patch 2.4.67 addresses the issue. No public exploit or active exploitation confirmed at time of analysis, but SSVC framework rates technical impact as total, indicating complete system compromise potential.
Buffer over-read in Apache HTTP Server through 2.4.66 enables remote unauthenticated information disclosure at network scale. Attackers can read sensitive memory content without authentication or user interaction, achieving high confidentiality impact with low attack complexity. EPSS exploitation probability and KEV status not provided, but SSVC framework confirms the vulnerability is automatable with partial technical impact and no active exploitation detected at time of analysis. Patch released in version 2.4.67.
Local .htaccess authors can escalate privileges to read arbitrary files as the httpd daemon user in Apache HTTP Server 2.4.66 and earlier. The vulnerability requires low-privilege authenticated access to create or modify .htaccess files, but exploits misconfigured module interactions to bypass intended access controls. Apache has released version 2.4.67 to address this issue. SSVC assessment indicates no active exploitation and non-automatable attack vector, with EPSS data not yet available for this recent disclosure.
Remote code execution in Apache MINA 2.1.0-2.1.11 and 2.2.0-2.2.6 allows unauthenticated attackers to execute arbitrary code via unsafe deserialization. The fix for prior CVE-2024-52046 was incomplete-the classname allowlist protecting IoBuffer.getObject() was applied too late, allowing malicious static initializers to execute before filtering. Confirmed actively exploited (CISA KEV). EPSS exploitation probability not provided, but the network-accessible, unauthenticated attack vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:N) combined with KEV status indicates immediate patching is critical for applications calling IoBuffer.getObject().
Remote unauthenticated code execution in Apache MINA 2.1.0-2.1.11 and 2.2.0-2.2.6 allows attackers to bypass class allowlist protections via unsafe deserialization. The vulnerability exists because the fix for CVE-2026-41635 was not backported to the 2.1.X and 2.2.X branches, leaving AbstractIoBuffer.resolveClass() susceptible to arbitrary class instantiation when applications call IoBuffer.getObject(). Only applications actively using MINA's deserialization features are affected. EPSS data not available; no KEV listing or public POC identified at time of analysis.
Algorithmic complexity denial of service in Apache Neethi allows remote unauthenticated attackers to exhaust JVM heap memory via malicious WS-Policy documents. Specially crafted policy documents trigger exponential Cartesian cross-product expansion during normalization, generating unbounded policy alternatives that consume all available memory. Apache has released version 3.2.2 with normalization limits to prevent exploitation. EPSS data not available; no CISA KEV listing identified at time of analysis.
Denial of Service in Apache Neethi WS-Policy processor allows remote unauthenticated attackers to crash applications or cause resource exhaustion by sending crafted policy documents with circular references. The vulnerability (CVSS 7.5) triggers infinite loops or stack overflow during policy normalization when Policy A references Policy B which references Policy A. Apache released version 3.2.2 to address this flaw. With network vector, low complexity, and no authentication required (AV:N/AC:L/PR:N), this represents a readily exploitable attack surface for applications parsing untrusted WS-Policy documents, though no public exploit or active exploitation (KEV) has been identified at time of analysis.
Unsafe Java deserialization in Apache Camel's camel-consul component (ConsulRegistry / ConsulRegistryUtils.deserialize) lets an attacker who can write to the backing Consul KV store achieve arbitrary code execution inside the Camel process. Any deployment using a Consul-backed Camel registry on versions 3.0.0 up to 4.14.6 or 4.15.0 up to 4.18.1 is affected. There is no public exploit identified at time of analysis, EPSS is low (0.08%), and this is a missed instance of the same deserialization class fixed in CVE-2024-22369, CVE-2024-23114 and CVE-2026-25747.
Remote code execution in Apache Camel's camel-coap component (versions 4.14.0-4.14.5, 4.18.0 before 4.18.1, and 4.19.0) allows an unauthenticated attacker to inject arbitrary internal Camel headers via CoAP URI query parameters, achieving OS command execution when a route forwards to a header-sensitive producer such as camel-exec. The component maps incoming CoAP query parameters straight into Exchange message headers with no HeaderFilterStrategy, so a single UDP packet to port 5683 can override the executable and arguments of a downstream exec producer and return command output in the CoAP response. Rated CVSS 10.0 with publicly available exploit code, though EPSS remains modest (0.55%, 68th percentile) and CISA SSVC records no observed exploitation, indicating opportunity rather than confirmed mass exploitation.
Message header injection in Apache Camel's camel-mail component (3.0.0 before 4.14.6 and 4.15.0 before 4.18.1) lets an attacker who can email a monitored mailbox smuggle Camel-prefixed MIME headers into the Exchange. Because MailHeaderFilterStrategy filters only the outbound direction and never sets an inbound filter, inbound Camel headers reach downstream components such as camel-bean, camel-exec, or camel-sql where they can alter route behavior, potentially reaching command or query execution. There is no public exploit identified at time of analysis and EPSS is very low (0.02%), but the vendor rates it CVSS 9.4 and SSVC marks it automatable.
Authentication bypass in Apache Camel's camel-platform-http-main component (versions 4.14.1–4.14.5 and 4.18.0–4.18.1) allows remote unauthenticated attackers to reach protected business routes and management endpoints when a non-root context path is configured. Because the Vert.x sub-router registers the auth handler at the exact context path rather than its subpaths, requests to paths like /api/route or /admin/observe/info evade the credential challenge, exposing runtime metadata (user, working directory, PID, JVM and OS details) via /observe/info. No public exploit identified at time of analysis; EPSS is low (0.04%) and CISA SSVC records no known exploitation, though the flaw is assessed as automatable.
Unsafe Java deserialization in Apache Camel's camel-infinispan component allows arbitrary code execution when the ProtoStream-based remote aggregation repository reads objects from an Infinispan cache using java.io.ObjectInputStream with no ObjectInputFilter applied. Any attacker able to write to the backing Infinispan cache can plant a malicious serialized gadget that executes in the application context during routine get/recover operations. Publicly available exploit code exists, though EPSS is low (0.08%) and there is no evidence of active exploitation.
Remote unauthenticated attackers can execute arbitrary code in Apache MINA 2.0.0-2.0.27, 2.1.0-2.1.10, and 2.2.0-2.2.5 through unsafe deserialization in AbstractIoBuffer.getObject(). This is an incomplete fix bypass for CVE-2024-52046 where the classname allowlist validation occurs after static initializers execute, enabling attackers to trigger malicious code execution before security controls engage. Apache confirmed the flaw affects applications calling IoBuffer.getObject() and released patches in versions 2.0.28, 2.1.11, and 2.2.6. CVSS 9.8 critical score reflects network-accessible unauthenticated exploitation with complete system compromise potential.
Remote code execution in Apache ActiveMQ allows authenticated attackers with admin console access to inject malicious Spring XML contexts that execute arbitrary code on the broker's JVM. Attackers exploit improper broker name validation to embed xbean bindings, then trigger VM transport creation via DestinationView mbean to load remote Spring XML files containing malicious bean factory methods like Runtime.exec(). EPSS score of 0.06% (19th percentile) indicates low observed exploitation probability despite CVSS 8.8, with CISA SSVC confirming no active exploitation and non-automatable attack chain. Vendor patches available: versions 5.19.6 and 6.2.5 address the vulnerability.
Remote code execution in Apache ActiveMQ 5.x (before 5.19.6) and 6.x (before 6.2.5) allows authenticated attackers to bypass prior security fixes (CVE-2026-34197) by injecting malicious Spring XML configurations through HTTP Discovery transport connectors via Jolokia. Attackers leverage a VM transport loophole to invoke arbitrary bean factory methods like Runtime.exec() during Spring context initialization. EPSS score is low (0.06%, 19th percentile) with no confirmed active exploitation (not in CISA KEV), suggesting limited widespread targeting despite high CVSS 8.8 score. Exploitation requires authenticated Jolokia access and presence of activemq-http module on classpath.
Apache HttpClient 5.6 skips mutual authentication verification in SCRAM-SHA-256 handshakes, allowing network attackers to impersonate legitimate servers without credentials. Affected clients accept unauthenticated server responses, enabling man-in-the-middle attacks that compromise confidentiality and integrity of authenticated sessions. Apache released patched version 5.6.1 addressing the missing authentication check. EPSS score of 0.03% suggests low current exploitation activity, though the network-accessible attack surface (AV:N/AC:L/PR:N) and availability of detailed vendor advisory increase exploitation risk once attackers adapt tooling for SCRAM protocol manipulation.
Apache Kafka 4.1.0 and 4.1.1 accept forged JWT tokens without signature validation, allowing remote unauthenticated attackers to authenticate as any user and gain unauthorized access to Kafka resources. The default SASL/OAUTHBEARER validator (DefaultJwtValidator) fails to verify token signatures, issuers, or audiences, enabling complete authentication bypass. CVSS 9.1 (Critical) with network vector and no privileges required. SSVC indicates the vulnerability is automatable with partial technical impact. No active exploitation confirmed at time of analysis, but the attack requires minimal sophistication and could be scripted trivially given the token acceptance behavior.
Command injection in Apache Airflow's BashOperator documentation example allows authenticated attackers to escalate privileges from UI user to worker-level code execution. Affects all Airflow versions before 3.2.0. The vulnerability stems from documentation suggesting unsafe handling of dag_run.conf parameters, which organizations may have replicated in production DAGs. EPSS score of 0.03% indicates low observed exploitation probability, though the upstream fix (PR #64129) demonstrates vendor acknowledgment and remediation.
Apache Airflow before 3.2.0 exposes SQL exception stack traces through API responses despite api/expose_stack_traces=false configuration, allowing remote unauthenticated attackers to enumerate database schema details, table names, query structure, and internal filesystem paths. CVSS 7.5 (High) with network vector and no authentication required. EPSS score of 0.02% (4th percentile) indicates low probability of widespread exploitation. Vendor patch available in Airflow 3.2.0 per Apache advisory. No active exploitation confirmed (not in CISA KEV) and no public POC identified at time of analysis.
Deserialization vulnerability in Apache Airflow webserver (all versions before 3.2.0) allows network-accessible attackers to execute arbitrary code by injecting malicious XCom payloads, despite vendor-assigned Low severity due to the trusted Dag Author threat model. CVSS 9.8 Critical rating reflects unauthenticated network-based RCE capability (AV:N/PR:N), contradicting the description's trust assumption. EPSS 0.07% (22nd percentile) suggests low immediate exploitation likelihood. No active exploitation confirmed; vendor patch available in version 3.2.0 with public GitHub PR.
Apache Airflow 3.0.x prior to 3.2.0 allows remote unauthenticated attackers to trigger unauthorized DAG (Directed Acyclic Graph) execution via the UI or API, bypassing asset materialize permission checks. Despite CVSS 7.5 HIGH, the CVSS vector (PR:N) contradicts the description's requirement for 'UI/API user with asset materialize permission', suggesting authentication IS required-a critical discrepancy that demands verification. EPSS of 0.01% (3rd percentile) indicates minimal observed exploitation activity. Vendor-released patch available in Airflow 3.2.0 per Apache advisory.
Apache Airflow 3.0.0 through 3.1.x exposes JWT authentication tokens in application logs, allowing any authenticated UI user with log access to escalate privileges and impersonate DAG Authors. CVSS rates this 7.5 HIGH for confidentiality impact, though the EPSS score of 0.02% (5th percentile) suggests minimal observed exploitation attempts. No active exploitation is confirmed; vendor patch available in version 3.2.0 released April 2026.
Unauthenticated access to Apache SkyWalking 9.7.0 to 10.3.0 allows remote attackers to retrieve sensitive MySQL/PostgreSQL configuration details through the /debugging/config/dump endpoint. No active exploitation or public exploit code is known, though the attack is trivial and automatable. The low EPSS score (0.02%) indicates minimal real-world exploitation likelihood.
Sensitive authentication tokens in Apache APISIX OpenID Connect plugin transmit in cleartext when connecting to identity providers, affecting versions 0.7 through 3.15.0. The ssl_verify parameter defaults to false, disabling TLS certificate validation and enabling potential man-in-the-middle interception of authentication credentials. With CVSS 7.5 (High), network-based attackers can intercept confidential data without authentication. EPSS probability is minimal (0.01%, 2nd percentile) with no confirmed active exploitation (CISA KEV absent), indicating theoretical risk despite high CVSS severity.
Header injection in Apache APISIX 2.12.0 through 3.15.0 lets remote attackers smuggle attacker-controlled HTTP headers through the forward-auth plugin when it is configured to relay client headers to an external authentication service. Because injected headers can spoof identity or authorization data trusted by the upstream auth endpoint, this can lead to authentication bypass or privilege escalation. There is no public exploit identified at time of analysis and EPSS is very low (0.03%), but CISA's SSVC framework rates the technical impact as total and the attack as automatable.
Remote code execution in Apache Airflow 3.1.x allows authenticated DAG Authors to execute arbitrary code in the webserver context through crafted XCom payloads exploiting insecure deserialization (CWE-502). Affects Apache Airflow versions 3.1.8 through <3.2.0. Despite CVSS 8.8, vendor rates severity as Low due to DAG Authors being highly trusted roles. No public exploit identified at time of analysis, with EPSS exploitation probability at 0.07% (21st percentile), indicating minimal real-world risk. Vendor-released patch: Apache Airflow 3.2.0.
Server-Side Request Forgery in Apache SkyWalking MCP 0.1.0 allows authenticated remote attackers to access internal network resources and exfiltrate sensitive data via a malicious SW-URL header. CVSS 7.1 (High severity) with network attack vector and low complexity. No public exploit identified at time of analysis, SSVC framework indicates no active exploitation and non-automatable attack requiring manual interaction with internal architecture knowledge.
Remote code execution in Apache Storm before 2.8.6 allows authenticated users with topology submission rights to execute arbitrary code on Nimbus and Worker JVMs via crafted serialized objects in Kerberos TGT credentials. The vulnerability exploits unsafe deserialization in the Nimbus Thrift API (CWE-502) with CVSS 8.8. No active exploitation confirmed (EPSS 0.30%, SSVC exploitation status: none), but the low attack complexity and network attack vector make this a critical patch priority for Storm deployments with authenticated users.
Out-of-memory denial of service in Apache ActiveMQ allows unauthenticated remote attackers to exhaust broker memory via rapid TLSv1.3 KeyUpdate requests. Affects ActiveMQ Client, Broker, and All distributions versions <5.19.4 and 6.0.0-6.2.3 when NIO SSL transports are used. Vulnerability arises from improper handling of TLSv1.3 handshake KeyUpdate messages, enabling clients to trigger unbounded memory allocation in the SSL engine. No public exploit identified at time of analysis. CVSS 7.5 (AV:N/AC:L/PR:N) indicates network-accessible, low-complexity attack requiring no authentication.
Apache Tomcat's cloud membership clustering component logs Kubernetes bearer tokens in plaintext, enabling unauthenticated remote attackers to extract authentication credentials from log files. Affects Tomcat 9.0.13-9.0.116, 10.1.0-M1-10.1.53, and 11.0.0-M1-11.0.20. CVSS 7.5 (High) reflects confidentiality impact; no public exploit identified at time of analysis. Exploitation requires network access to log files or log aggregation systems, potentially enabling privilege escalation within Kubernetes clusters.
Missing encryption of cluster replication traffic in Apache Tomcat 11.0.20, 10.1.53, and 9.0.116 exposes sensitive session data to network-positioned attackers because the EncryptInterceptor - the clustering security control - can be bypassed due to a regression introduced by the fix for CVE-2026-29146. Listed in CISA KEV as actively exploited with a publicly available exploit, though EPSS sits at just 0.01% (1st percentile), indicating targeted rather than widespread automated exploitation. The confidentiality impact is rated High with no integrity or availability impact, consistent with CWE-311 (Missing Encryption of Sensitive Data).
Information disclosure in Apache Tomcat's JsonAccessLogValve allows unauthenticated remote attackers to retrieve sensitive data due to improper output encoding. Affects Tomcat versions 11.0.0-M1 through 11.0.20, 10.1.0-M1 through 10.1.53, and 9.0.40 through 9.0.116. The vulnerability enables high-impact confidentiality breaches through network-accessible attack vectors with low complexity and no user interaction required. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.02%).
Padding oracle attack in Apache Tomcat EncryptInterceptor leaks encrypted session data confidentiality across versions 7.0.100-7.0.109, 8.5.38-8.5.100, 9.0.13-9.0.115, 10.0.0-M1-10.1.52, and 11.0.0-M1-11.0.18 when default configuration is deployed. Unauthenticated remote attackers exploit oracle responses to decrypt sensitive information without authentication (CVSS:3.1 AV:N/AC:L/PR:N). CWE-209 (information exposure through error messages) enables cryptographic side-channel extraction. No public exploit identified at time of analysis; low observed exploitation activity (EPSS 0.02%).
Authentication bypass in Apache Tomcat 9.x through 11.x and Tomcat Native 1.1.23-2.0.13 allows unauthenticated remote attackers to bypass CLIENT_CERT authentication when soft-fail is disabled, achieving unauthorized access to confidentiality- and integrity-sensitive resources. Exploitation requires no user interaction or privileges (CVSS:3.1 PR:N/UI:N). The flaw affects CLIENT_CERT authentication logic, permitting access under conditions where authentication should fail. No public exploit identified at time of analysis; low observed exploitation activity (EPSS 0.04%).
Cipher preference order enforcement failure in Apache Tomcat 9.0.114-9.0.115, 10.1.51-10.1.52, and 11.0.16-11.0.18 allows unauthenticated remote attackers to force selection of weaker cryptographic ciphers during TLS negotiation, enabling potential decryption of confidential data transmitted over HTTPS connections. The vulnerability stems from improper preservation of administrator-configured cipher suite priority, potentially exposing sensitive session data, credentials, or application content. No public exploit identified at time of analysis. CVSS 7.5 (High) reflects network-accessible confidentiality impact requiring no privileges.
HTTP request smuggling in Apache Tomcat 7.x through 11.x permits unauthenticated remote attackers to manipulate request routing and bypass security controls via malformed chunk extension processing. Exploitation enables header injection, cache poisoning, and request routing manipulation without code execution. Affects Tomcat 7.0.0-7.0.109, 8.5.0-8.5.100, 9.0.0.M1-9.0.115, 10.1.0-M1-10.1.52, and 11.0.0-M1-11.0.18. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.02%).
Remote denial-of-service in Apache ActiveMQ 6.0.0 through 6.2.3 allows unauthenticated network attackers to crash the MQTT broker via malformed control packets. An integer overflow in the MQTT protocol handler's remaining length field validation enables resource exhaustion without authentication. This vulnerability stems from an incomplete patch - the fix for CVE-2025-66168 was applied only to 5.19.x branches but omitted from all 6.x releases until 6.2.4. No public exploit identified at time of analysis. Low observed exploitation activity (EPSS 0.02%).
Hard-coded cryptographic key in Apache OpenMeetings 6.1.0-9.0.0 enables cookie-based credential theft. The default remember-me cookie encryption key in openmeetings.properties is not auto-rotated, allowing attackers who steal session cookies to decrypt and extract full user credentials without authentication. This unauthenticated network-accessible vulnerability achieves high confidentiality impact through cryptographic weakness. No public exploit identified at time of analysis. EPSS indicates low observed exploitation activity.
Apache OpenMeetings REST login endpoint exposes credentials through HTTP GET query parameters, enabling credential harvesting via browser history, server logs, referrer headers, and intermediate proxies. Affects versions 3.1.3 through 8.x. CVSS 7.5 HIGH reflects unauthenticated network-accessible information disclosure with no user interaction required. No public exploit identified at time of analysis, low observed exploitation activity (EPSS 0.02%).
Apache Cassandra 5.0 through 5.0.6 in mTLS environments using MutualTlsAuthenticator allows authenticated users with only CREATE permission to escalate privileges to superuser via certificate identity manipulation through the ADD IDENTITY command. CVSS 8.8 reflects high impact across confidentiality, integrity, and availability. No public exploit identified at time of analysis, with SSVC indicating non-automatable exploitation but total technical impact. Apache released patch version 5.0.7+ addressing this privilege escalation flaw (CWE-267: Privilege Defined With Unsafe Actions).
Buffer use-after-free in Apache Kafka Java producer client (versions ≤3.9.1, ≤4.0.1, ≤4.1.1) can silently route messages to incorrect topics when batch expiration races with in-flight network requests. CVSS 8.7 (High) with network-accessible attack vector and high complexity. CISA SSVC indicates no active exploitation, non-automatable attack, and partial technical impact. No public exploit identified at time of analysis. EPSS data not provided, but the combination of high CVSS, cross-scope impact (S:C), and dual confidentiality/integrity impact warrants prioritization for environments processing sensitive message streams.
Remote code execution in Apache ActiveMQ Classic versions before 5.19.5 and 6.0.0-6.2.2 allows authenticated attackers to execute arbitrary code on the broker's JVM via Jolokia MBean operations. Attackers with low-privilege web console access can invoke BrokerService.addNetworkConnector() with a malicious discovery URI containing a VM transport brokerConfig parameter that loads remote Spring XML contexts, triggering bean instantiation and code execution through factory methods like Runtime.exec(
