Full takeover of Oracle JD Edwards EnterpriseOne Human Resources Management 9.2 is possible when a low-privileged attacker with network access to the JDENET service chains a hard-to-exploit flaw in the Human Resources component. Successful exploitation yields high confidentiality, integrity, and availability impact (complete compromise of the HR module). No public exploit has been identified at time of analysis and it is not listed in CISA KEV; risk is tempered by high attack complexity (AC:H) and a required authenticated foothold (PR:L).
Full compromise of Oracle JD Edwards EnterpriseOne CRM Foundation 9.2 is possible when a low-privileged attacker with network access abuses the proprietary JDENET communication protocol, per Oracle's July 2026 Critical Patch Update. Successful exploitation yields complete takeover of the CRM Foundation component with high confidentiality, integrity, and availability impact, though Oracle rates the attack complexity as high. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Full product takeover of Oracle JD Edwards EnterpriseOne Advanced Pricing - Procurement (version 9.2) is possible via the proprietary JDENET network protocol, where a low-privileged, network-authenticated attacker can compromise confidentiality, integrity, and availability. Oracle rates this CVSS 3.1 7.5, tempered by high attack complexity (AC:H), meaning exploitation is not straightforward. There is no public exploit identified at time of analysis and it is not on CISA KEV; the fix ships in the Oracle Critical Patch Update of July 2026.
Full compromise of Oracle JD Edwards EnterpriseOne Requirements Planning 9.2 is possible for a low-privileged attacker reaching the proprietary JDENET network protocol, yielding confidentiality, integrity, and availability impact ("takeover"). The flaw carries a CVSS 3.1 base score of 7.5 but is rated hard to exploit (AC:H) and requires existing low-level privileges (PR:L). There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Full compromise of Oracle Cost Management (the Cost Maintenance component of Oracle E-Business Suite) is achievable over HTTP by a low-privileged, authenticated attacker, per Oracle's July 2026 Critical Patch Update.

There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Unauthorized data modification in Oracle PeopleSoft Enterprise FIN Staffing Front Office 9.2 allows a remote, unauthenticated attacker to create, delete, or modify critical data via crafted HTTP requests. The flaw is confined to the Staffing Front Office component and carries an integrity-only impact (CVSS 3.1 7.5, C:N/I:H/A:N). No public exploit identified at time of analysis, and the CVE is not listed in CISA KEV.
Denial of service in Oracle Unified Directory (OUD Core) versions 12.2.1.4.0 and 14.1.2.1.0 lets an unauthenticated attacker with LDAP network access hang or repeatedly crash the directory server, producing a complete availability outage. Oracle rates it CVSS 3.1 7.5 with availability-only impact and describes it as easily exploitable. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; confidentiality and integrity are unaffected.
Remote denial-of-service in Oracle Unified Directory (OUD Core) 12.2.1.4.0 and 14.1.2.1.0 lets an unauthenticated network attacker send crafted LDAP traffic that hangs or repeatedly crashes the directory service, producing a complete availability outage. Addressed in the Oracle Critical Patch Update of July 2026, the flaw carries CVSS 7.5 (availability-only) with no impact to confidentiality or integrity. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so exploitation is currently theoretical rather than observed.
Unauthorized data disclosure in Oracle Data Integrator (Oracle Fusion Middleware, Patchset Assistant component) versions 12.2.1.4.0 and 14.1.2.0.0 lets a remote, unauthenticated attacker read all data accessible to the product over HTTP. The flaw carries a CVSS 3.1 base score of 7.5 with confidentiality-only impact and was disclosed in Oracle's July 2026 Critical Patch Update; no public exploit identified at time of analysis. Vendor tagging references an authentication-bypass theme, consistent with the PR:N (no-privilege) requirement.
Unauthorized data disclosure in Oracle Siebel CRM Cloud Applications (Siebel Cloud Manager component), versions 22.3 through 26.5, lets a remote unauthenticated attacker reach sensitive data over HTTP. The flaw is tagged as an authentication bypass and, per Oracle's own scoring, is 'easily exploitable' with a high confidentiality impact but no integrity or availability effect (CVSS 3.1 base 7.5). No public exploit identified at time of analysis, and it is not listed in CISA KEV; EPSS was not provided in the source data.
Full product takeover of Oracle WebCenter Content (Content Server component) in versions 12.2.1.4.0 and 14.1.2.0.0 can be achieved by an unauthenticated remote attacker over HTTP, but only by luring a separate user into an interaction that triggers the flaw. Rated CVSS 3.1 7.5 with high confidentiality, integrity, and availability impact, the issue is classified 'difficult to exploit' due to high attack complexity and the required human interaction. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so the practical risk is gated by the social-engineering step despite the severe potential impact.
Account/application takeover in Oracle WebCenter Content: Imaging (Core component of Fusion Middleware) affects supported versions 12.2.1.4.0 and 14.1.2.0.0, where a remote unauthenticated attacker who lures a legitimate user into interacting with malicious content over HTTP can fully compromise the Imaging application. Oracle rates it CVSS 3.1 7.5 with high confidentiality, integrity, and availability impact, but flags it as difficult to exploit (AC:H) and dependent on user interaction. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; a fix ships in the Oracle July 2026 Critical Patch Update.
Unauthenticated information disclosure in Oracle PeopleSoft Enterprise FIN Common Objects Brazil 9.1 (Staffing component) lets a remote attacker send crafted HTTP requests to read critical data, potentially achieving complete access to all data accessible to the affected module. Oracle rates it easily exploitable with a CVSS 3.1 base score of 7.5, but the impact is confined to confidentiality (no integrity or availability effect). There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Unauthorized data disclosure in Oracle PeopleSoft Enterprise FIN Common Objects Brazil 9.1 (Common Objects component) allows a remote unauthenticated attacker to reach and read critical financial data over HTTP. Oracle rates it easily exploitable with a CVSS 3.1 base of 7.5 and confidentiality-only impact (C:H/I:N/A:N), and it is addressed in Oracle's July 2026 Critical Patch Update. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Unauthorized data disclosure in Oracle Application Object Library (a core component of Oracle E-Business Suite, versions 12.2.3 through 12.2.15) allows a remote, unauthenticated attacker to compromise confidentiality over HTTP, resulting in unauthorized access to critical data or complete access to all data accessible to Oracle Application Object Library. Fixed in Oracle's July 2026 Critical Patch Update, the flaw is tagged as an authentication bypass and carries a CVSS 3.1 base score of 7.5 driven entirely by confidentiality impact (C:H, I:N, A:N). There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.
Unauthenticated data disclosure in Oracle Application Testing Suite 13.3.0.1 lets a remote attacker with only TCP network access read critical application data, potentially gaining complete access to all data reachable by the product. The flaw is tagged as an authentication bypass and was disclosed in Oracle's July 2026 Critical Patch Update; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Impact is confined to confidentiality - integrity and availability are unaffected per the CVSS vector.
Integrity-protection bypass in libssh builds compiled against the OpenSSL crypto backend, caused by incorrect AES-GCM finalization checks that fail to verify the authentication tag. An in-path (man-in-the-middle) attacker positioned on an SSH session can silently alter plaintext bytes on the wire without triggering a MAC/integrity failure, defeating a core guarantee of the SSH transport layer. There is no public exploit identified at time of analysis, EPSS risk is low (0.28%, 20th percentile), and CISA SSVC rates exploitation as 'none' though 'automatable: yes'.
Unauthorized data disclosure in Oracle Complex Maintenance, Repair and Overhaul (CMRO), a module of Oracle E-Business Suite 12.2.3 through 12.2.15, lets a remote unauthenticated attacker abuse the Internal Operations component over HTTP to read critical CMRO data and make limited unauthorized modifications. Because the flaw carries a scope change, a successful attack can significantly impact products beyond CMRO itself. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV; the CVSS 3.1 base score is 7.5 with high attack complexity, so exploitation is rated difficult.
Unauthorized critical-data access in Oracle JDeveloper (Fusion Middleware, Data Visualization Tools component) versions 12.2.1.4.0 and 14.1.2.0.0 lets a remote unauthenticated attacker read all JDeveloper-accessible data and modify some of it over HTTP, with a scope change that can significantly impact adjacent Oracle products. Oracle rates it CVSS 3.1 7.5 but flags it as difficult to exploit (AC:H). No public exploit identified at time of analysis and it is not listed in CISA KEV, so risk is currently theoretical but non-trivial given the unauthenticated network vector.
Full compromise (takeover) of Oracle Process Manufacturing Process Execution 12.2.15, a module of Oracle E-Business Suite (component: Internal Operations), is achievable by a low-privileged, authenticated attacker over HTTP. Successful exploitation yields high confidentiality, integrity, and availability impact against the module, though Oracle rates the attack complexity as high ('difficult to exploit'). No public exploit identified at time of analysis, and it is not listed in CISA KEV; the fix ships in Oracle's July 2026 Critical Patch Update.
Takeover of Oracle Purchasing (a module of Oracle E-Business Suite, Internal Operations component) is possible for a low-privileged, network-authenticated attacker in supported releases 12.2.11 through 12.2.15. Successful attacks yield full confidentiality, integrity, and availability compromise of the Purchasing application per Oracle's July 2026 Critical Patch Update. Exploitation is rated high-complexity (AC:H), and no public exploit identified at time of analysis; the issue was reported internally by Oracle's security alert team rather than a public researcher.
Missing authentication in exo-explore's exo 1.0.69 distributed AI inference framework lets remote unauthenticated attackers reach the GET /state and DELETE /instance/{instance_id} management endpoints, exposing cluster state and destroying running inference instances. Classified CWE-306 with CVSS 7.5 (availability-focused), it carries a low EPSS of 0.27% and is not on CISA KEV; a third-party writeup exists but no public exploit is confirmed. The practical effect is denial of service and unauthorized administrative control over the AI node cluster.
Information disclosure in Mozilla Firefox's Networking: WebSockets component allows remote attackers to read sensitive data across origin or trust boundaries without authentication or user interaction. The flaw affects Firefox releases prior to 153 and the ESR line prior to 140.13, and is corrected in those fixed builds. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV, but the network-reachable, no-privilege CVSS 7.5 profile makes it a broad exposure across the very large Firefox install base.
Directory traversal in Knowns 0.11.4 (the 'knowns' npm CLI/MCP knowledge layer for AI-assisted development) lets an attacker supply a crafted folder name to the create_doc tool and cause documents to be created outside the intended workspace directory. Because create_doc is exposed to AI agents via MCP, a malicious or manipulated tool call can traverse the filesystem using sequences such as '../'. A researcher gist and an upstream fix commit are referenced, so publicly available exploit code exists; the flaw is not in CISA KEV and carries a low EPSS score (0.26%, 18th percentile), indicating no evidence of widespread active exploitation.
Arbitrary file read (and likely write) in the Knowns 0.11.4 AI knowledge-layer server allows remote attackers to escape the intended document directory by supplying crafted relative paths to its get_doc and update_doc MCP tools. Because Knowns exposes these tools to AI agents and self-hosted clients, an attacker who can reach the tool interface can retrieve or tamper with files outside the managed knowledge store. EPSS is low (0.26%, 18th percentile) and there is no public exploit identified at time of analysis, though an upstream fix commit and a researcher gist both exist.
Unauthorized data modification in Oracle Java SE, GraalVM for JDK, and GraalVM Enterprise Edition (Libraries component) lets a remote, unauthenticated attacker corrupt, create, or delete critical data by feeding crafted input to affected Java APIs, for example through a web service that passes data to those APIs. It carries CVSS 3.1 7.5 with an integrity-only impact (C:N/I:H/A:N) and is described by Oracle as easily exploitable over multiple network protocols. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the ubiquity of the Java runtime makes patching a priority.
Denial of service (and potential use-after-free) in libssh occurs when the library processes SSH data packets that arrive after a channel has been closed, causing channel data callbacks to fire against already-freed memory. Any application or system linking the affected libssh - including Red Hat Enterprise Linux 8, 9, and 10 and Red Hat Hardened Images - can be crashed by a malicious SSH peer that sends channel data at the wrong point in the connection lifecycle. There is no public exploit identified at time of analysis, EPSS is low (0.26%), and CISA SSVC scores exploitation as none, indicating a real but non-urgent memory-safety fix.
Denial of service in the golang.org/x/text/unicode/norm package (versions before 0.39.0) allows remote attackers to cause an unrecoverable infinite loop by supplying input containing invalid UTF-8 bytes to a norm.Iter. Any Go service that Unicode-normalizes untrusted input using this widely-used supplementary library can be hung with a single malformed request, consuming CPU until the process is killed. No public exploit identified at time of analysis; EPSS is low (0.22%, 13th percentile), but the network-reachable, no-authentication, no-interaction profile makes it broadly triggerable.
Information disclosure in DayuanJiang next-ai-draw-io 0.4.13, an open-source Next.js application that generates draw.io diagrams via AI providers, allows a remote attacker to obtain sensitive information through the x-ai-provider component. The flaw is reported as unauthenticated and network-reachable (CVSS 7.5, confidentiality-only), and no public exploit was identified at time of analysis, though a third-party technical write-up exists. EPSS is low (0.22%, 13th percentile) and the CVE is not listed in CISA KEV.
Full compromise of the Oracle Enterprise Command Center Framework (Core component of Oracle E-Business Suite) V16 is possible for an unauthenticated attacker who has adjacent-network access to the physical segment attached to the host, resulting in complete takeover with high confidentiality, integrity, and availability impact. Exploitation is rated difficult (high attack complexity) and requires the attacker to already sit on the same communication segment as the server, so it is not a remotely-reachable internet flaw. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV; it was reported by Oracle's own security team and addressed in the July 2026 Critical Patch Update.
Information disclosure in aiflowy (an open-source Java/Spring-based AI workflow / low-code platform) versions 2.1.2 and earlier lets remote unauthenticated attackers extract sensitive information through the JobUtil.java scheduling component. The public technical writeup titled 'Any SpringBean invocation' indicates the flaw stems from unrestricted invocation of arbitrary Spring beans, which can be abused to read internal application state and secrets. No CISA KEV listing and a low EPSS score (0.19%, 9th percentile) suggest no observed mass exploitation, but a public technical analysis describing the technique exists.
SQL injection in AiFlowy versions 2.1.2 and earlier lets remote attackers extract sensitive database contents through the getPageData method in DatacenterQuery.java. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) indicates unauthenticated, low-complexity network exploitation with high confidentiality impact but no integrity or availability effect. A public technical write-up with reproduction details exists on GitHub, though the low EPSS score (0.19%, 8th percentile) and absence from CISA KEV indicate no confirmed active exploitation at time of analysis.
Improper TLS certificate validation in Gitea versions prior to 1.27.0 lets an on-path attacker intercept the internal API channel and steal the static, high-privilege INTERNAL_TOKEN. The internal API HTTP client (modules/private/internal.go) hardcodes InsecureSkipVerify:true with no config override, so gitea serv / gitea hook subprocesses accept any certificate when LOCAL_ROOT_URL uses HTTPS to a non-loopback host. A detailed proof-of-concept is published in the vendor advisory, but there is no evidence of active exploitation; the token grants full control over every /api/internal/* endpoint, including server shutdown, SSH key authorization, and arbitrary git command execution.
Server-side request forgery in Gitea ≤1.26.4 allows privileged users to bypass the platform's own hostmatcher SSRF defenses via three unprotected raw http.Get() code paths in the migration and OAuth avatar subsystems, enabling retrieval of cloud instance metadata (AWS IMDSv1, GCP tokens), local file read (e.g., app.ini with database credentials and JWT secrets), and internal network scanning. A detailed proof-of-concept exploit is publicly available in the GitHub Security Advisory GHSA-2wm4-vwp6-v7xc. EPSS is low at 0.16% (6th percentile), consistent with the privilege requirements limiting opportunistic exploitation, but the disclosed PoC and the sensitivity of reachable data elevate real-world risk for cloud-hosted deployments. No active exploitation is confirmed in CISA KEV at time of analysis.
Private organization member enumeration in Gitea allows any authenticated user to retrieve the full member roster - including emails - of a private organization via the /api/v1/orgs/{org}/members endpoint. The root cause is an incomplete fix: PR #38145 added visibility guards to ListPublicMembers and IsPublicMember but omitted the same guard from ListMembers, leaving a single missing HasOrgOrUserVisible check in routers/api/v1/org/member.go. Proof-of-concept code is publicly available in the GitHub Security Advisory; no active exploitation has been confirmed in CISA KEV, and the EPSS score of 0.16% (5th percentile) indicates low probability of widespread automated exploitation.
Gitea's REST API leaks private organization membership through the `GET /orgs/{org}/public_members/{username}` endpoint, bypassing the visibility controls that correctly conceal this information in the web UI. All versions up to and including 1.26.4 are affected, permitting any user with a valid API token to confirm whether a specific user belongs to a hidden organization - data intentionally withheld from the web interface. No public exploit is confirmed in CISA KEV, though a detailed proof-of-concept with curl commands is documented in GHSA-jr5x-6h83-wrxf; EPSS stands at 0.16% (5th percentile), indicating low observed exploitation probability.
Unauthenticated denial of service in Gitea's Locale middleware allows any remote attacker to consume ~2 seconds of server CPU per HTTP request by crafting a ~1 MiB Accept-Language header composed of underscore separators, bypassing the existing CVE-2022-32149 guard in golang.org/x/text which only counts dash characters. All Gitea releases from 1.22.x through 1.26.x are affected because the middleware at modules/web/middleware/locale.go:38 passes the raw, unfiltered header directly to the quadratic-time ParseAcceptLanguage parser; ten concurrent attackers consuming ~10 MiB/s of upstream bandwidth can saturate all cores of a ten-core host indefinitely. Publicly available exploit code exists in the GHSA advisory; no active exploitation has been confirmed by CISA KEV at time of analysis.
Information disclosure in Mozilla Firefox's ImageLib graphics component allows remote attackers to read sensitive data (likely uninitialized or out-of-bounds process memory) when a victim renders attacker-controlled image content, per the CWE-200 classification and the C:H CVSS impact. Affected builds are Firefox before 153 and the ESR 115.x and 140.x branches, all fixed by Mozilla in Firefox 153, ESR 115.38, and ESR 140.13. There is no public exploit identified at time of analysis and EPSS is low (0.15%, 5th percentile), consistent with a vendor-reported browser memory-disclosure issue rather than one under active exploitation.
Private repository metadata leaks through the starred and watched repository API endpoints in Gitea versions prior to 1.27.0, allowing former collaborators to continue retrieving - and receiving live updates to - repository metadata after access revocation. Any authenticated user who starred a private Gitea repository while holding collaborator access can call GET /api/v1/user/starred with their existing API token and receive current repository metadata, including description changes made after their removal. A public proof-of-concept is available; the vulnerability is not in CISA KEV and EPSS indicates low observed exploitation activity at 0.15% (5th percentile).
Information disclosure in Mozilla Firefox's Storage: IndexedDB component allows a remote attacker to leak sensitive data across origins or from other browsing contexts without authentication or user interaction. The flaw affects Firefox releases prior to 153 and ESR builds prior to 140.13; there is no public exploit identified at time of analysis, and its EPSS score (0.15%, 5th percentile) indicates low near-term exploitation likelihood despite a CVSS of 7.5. Mozilla has released fixed builds, so the practical priority is prompt browser updating rather than emergency response.
Information disclosure in the Firefox DevTools Framework component allows an attacker to read data that should remain isolated, affecting Mozilla Firefox prior to 153 and Firefox ESR prior to 140.13. Reported by Mozilla and carrying a CVSS 7.5 (high) rating driven by high confidentiality impact, there is no public exploit identified at time of analysis and the EPSS probability is low at 0.15% (5th percentile). The issue is fixed and not listed in CISA KEV.
Broken access control in Gitea's issue-dependency removal endpoint allows any authenticated user with issue-write access on one repository to delete cross-repository dependency links and inject attacker-authored comments into private repositories they have no read or write access to. All Gitea releases through v1.26.4 are affected; the sibling AddDependency function in the same source file performs the correct cross-repository permission check that RemoveDependency entirely omits. A working proof-of-concept curl command is published in the GitHub Security Advisory GHSA-xv9x-fj9g-vj6h, though no confirmed active exploitation (CISA KEV) has been identified and EPSS sits at 0.15% (4th percentile).
Information disclosure in Mozilla Firefox's Graphics WebGPU component allows a malicious web page to read uninitialized process memory, potentially leaking sensitive data such as heap contents, pointers, or cross-origin material, before the fix in Firefox 153. The flaw stems from WebGPU operating on memory that was never initialized (CWE-908), and while CVSS rates confidentiality impact High (7.5), EPSS is very low (0.14%, 4th percentile) with no public exploit and no CISA KEV listing. Exploitation is browser-based, requiring a victim to load attacker-controlled WebGPU content.
Information disclosure in Mozilla Firefox's Graphics WebGPU component allows a remote attacker to read leftover uninitialized memory, potentially exposing sensitive data such as other pages' content, GPU buffers, or process memory. The flaw stems from a WebGPU code path returning memory that was never zeroed, and is fixed in Firefox 153; there is no public exploit identified at time of analysis and the EPSS score is low (0.14%, 4th percentile).
Information disclosure in Mozilla Firefox's Graphics: WebGPU component allows remote attackers to read uninitialized memory contents via crafted WebGPU operations, potentially leaking sensitive process memory such as heap data, addresses, or other page content. The flaw is network-reachable without authentication or user interaction beyond visiting a malicious page, but carries no integrity or availability impact. There is no public exploit identified at time of analysis, and EPSS estimates a low 0.14% exploitation probability.
Information disclosure in Mozilla Firefox before version 153 stems from an input-validation flaw in the DOM Copy & Paste and Drag & Drop component, allowing remote content to potentially read data that should remain isolated. The provided CVSS vector rates confidentiality impact as High with no privileges or user interaction, and Mozilla has shipped a fix in Firefox 153. There is no public exploit identified at time of analysis, and the EPSS score of 0.14% (4th percentile) indicates low near-term exploitation likelihood.
Remote denial-of-service in Mozilla Firefox's Graphics: WebGPU component allows a malicious web page to exhaust browser resources and crash or hang the browser without any user credentials or interaction. The flaw affects Firefox versions prior to 153 and is triggered simply by loading attacker-controlled content that abuses the WebGPU API. There is no public exploit identified at time of analysis, and EPSS scores the exploitation likelihood at only 0.14%, indicating low near-term probability of widespread exploitation.
Information disclosure in the Privacy component of Mozilla Firefox for Android allows remote attackers to expose sensitive user data, with the flaw carrying a high confidentiality impact (CVSS 7.5). Mozilla self-reported and fixed the issue in Firefox 153 per advisory MFSA2026-68; there is no public exploit identified at time of analysis, and the EPSS probability is low (0.14%, 4th percentile). The Privacy component context suggests leakage of protected browsing state or user data that the browser is designed to isolate.
