Critical [CVE-2026-44024] Remote Code Execution via arbitrary file write due to insufficient tag validation
Fluentd collects events from various data sources and writes them to files, RDBMS, NoSQL, IaaS, SaaS, Hadoop and so on. Prior to 1.19.3, Fluentd allows dynamically constructing file paths using the ${tag} placeholder, and insufficient validation of ${tag} in file configurations such as the path parameter of the out_file plugin allows attackers sending untrusted tags containing path traversal characters to write or overwrite arbitrary files and potentially achieve remote code execution. This issue is fixed in version 1.19.3. A flaw was found in Fluentd, a data collector. Successful exploitation could lead to a full system compromise without authentication, depending on the Fluentd configuration and its process privileges. Red Hat has determined that no Red Hat product is currently affected by this vulnerability. Exploitation requires a Fluentd deployment configured with an output plugin, such as out_file, that constructs file paths dynamically from the ${tag} placeholder, combined with the ability for an attacker to submit untrusted, attacker-influenced tags to that Fluentd instance (for example, via an exposed forward or HTTP input). Deployments that do not accept externally influenced tags, or that do not use tag-based dynamic path construction in output plugin configuration, are not exposed to this issue in practice.
Critical [CVE-2026-54763] Identity spoofing via improper header handling in authentication middlewares
Traefik is an HTTP reverse proxy and load balancer. Prior to v2.11.51, v3.6.22, and v3.7.6, Traefik's BasicAuth, DigestAuth, and ForwardAuth middlewares strip canonical-cased spoofed identity headers before writing Traefik's own value, but do not account for underscore-variant header names, which many backends normalize identically to dashed forms. An attacker able to reach a protected route can inject an underscore-variant header that survives Traefik's stripping and reaches the backend alongside, or on the unauthenticated ForwardAuth authResponseHeaders path instead of, the value Traefik intended to set, spoofing identity or authorization context. This issue is fixed in versions v2.11.51, v3.6.22, and v3.7.6. This allows a remote attacker to inject a specially crafted header that bypasses Traefik's security mechanisms. As a result, the attacker can spoof identity or authorization context to the backend, potentially gaining unauthorized access to protected resources. This can lead to identity spoofing or unauthorized access to backend services, as Traefik fails to properly strip these headers before forwarding them. The vulnerability is significant because many backend systems normalize these header forms, making exploitation feasible in typical deployments. Red Hat severity: Important — CVSS 10 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N). Weakness: CWE-178.
Critical [CVE-2026-48614] Privilege escalation via improper authorization in XML API
An improper authorization vulnerability in the Plesk XML API allows an authenticated user to inject arbitrary configuration directives, resulting in arbitrary file write as root and full privilege escalation on the underlying server. A flaw was found in Plesk. Although the go-acme/lego dependency is present, Red Hat OpenShift Dev Spaces does not ship or use the affected Plesk functionality. Therefore, the vulnerable code path is not exposed in this product. Red Hat severity: Critical — CVSS 9.9 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H). Weakness: CWE-15.
Critical [CVE-2026-14544 +1] Incomplete Fix for CVE-2026-8631
A flaw was found in HPLIP (HP Linux Imaging and Printing Software). This vulnerability, an incomplete fix for CVE-2026-8631, may allow a remote attacker to escalate privileges or achieve arbitrary code execution. This can occur through an integer overflow in the hpcups processing path when handling specially crafted print data. A remote attacker who can submit print job content to the hpcups filter path may achieve arbitrary code execution or privilege escalation within user used for starting filters (user 'lp' by default) on systems using HPLIP for printing. Red Hat severity: Important — CVSS 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-190. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat fixing advisory: RHSA-2026:39976, RHSA-2026:40894, RHSA-2026:40831. Affected products named by the advisory: Red Hat package: hplip.
Critical [CVE-2026-58517] Authentication bypass due to improper input neutralization
Improper neutralization of input terminators vulnerability in The Wikimedia Foundation Mediawiki - WikiLambda Extension allows Authentication Bypass. This could lead to unauthorized access to the system. Red Hat severity: Critical — CVSS 9.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). Weakness: CWE-140.
Critical [CVE-2026-13283] Use after free in AdFilter
Use after free in AdFilter in Google Chrome on Android prior to 149.0.7827.201 allowed a remote attacker who convinced a user to engage in specific UI gestures to execute arbitrary code via a crafted HTML page. (Chromium security severity: High) An use after free flaw was found in the AdFilter component of the Chromium browser. Upstream bug(s): Red Hat Product Security rates the severity of this flaw as determined by the Google Chrome Security Advisory. Red Hat severity: Important — CVSS 9.6 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H). Weakness: CWE-825.
Critical [CVE-2026-13032] Use after free in WebGL
Use after free in WebGL in Google Chrome on Android prior to 149.0.7827.197 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical) An use after free flaw was found in the WebGL component of the Chromium browser. Upstream bug(s): Red Hat Product Security rates the severity of this flaw as determined by the Google Chrome Security Advisory. Red Hat severity: Critical — CVSS 9.6 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H). Weakness: CWE-825.
Critical [CVE-2026-44020] Information disclosure via XML External Entity (XXE) vulnerability
Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.13.0 until 2.74.0, the USPTO patent XML parser used the standard xml.sax.parseString() without protection against XML External Entity (XXE) attacks. An attacker could craft malicious USPTO patent XML files with external entity references that could read arbitrary files from the server filesystem, perform Server-Side Request Forgery (SSRF) attacks, or cause denial of service through entity expansion (Billion Laughs attack). The vulnerability affects three USPTO patent format parsers: ICE (v4.x), Grant v2.5, and Application v1.x. This vulnerability is fixed in 2.74.0. A flaw was found in docling. This is an Important vulnerability in docling, as shipped with Red Hat OpenShift AI, due to an XML External Entity (XXE) flaw in its USPTO patent XML parser. An attacker could exploit this by providing specially crafted XML files, leading to unauthorized access to local files, Server-Side Request Forgery (SSRF), or denial of service. The broad impact on data confidentiality and system availability elevates this to an Important severity. Red Hat severity: Important — CVSS 9.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:H). Weakness: CWE-611. Affected Red Hat products: Red Hat OpenShift AI (RHOAI).
Critical [CVE-2026-53622] mTLS enforcement bypass due to HTTP/3 TLS configuration flaw
Traefik is an HTTP reverse proxy and load balancer. Prior to 3.7.3, there is a critical vulnerability in Traefik's HTTP/3 (QUIC) TLS configuration selection that allows unauthenticated clients to bypass router-specific mTLS enforcement. When HTTP/3 is enabled on an entrypoint, the TLS handshake selects the applicable TLS configuration through an exact, case-sensitive lookup on the SNI value, which fails to match wildcard host patterns (e.g., *.example.com) or case variants of the configured hostname. Because the handshake falls back to the default TLS configuration — which may not require client certificates — a client can complete the QUIC handshake without presenting a certificate, while the subsequent HTTP routing layer still dispatches the request to a backend protected by a router-specific mTLS policy. The issue affects deployments where HTTP/3 is enabled, a router uses a wildcard Host rule or case-insensitive hostname matching, a router-specific TLSOptions enforces client certificate authentication, and UDP access to the entrypoint is reachable by an attacker. This vulnerability is fixed in 3.7.3. This bypass grants unauthorized access to a backend that should be protected by mTLS. Red Hat severity: Important — CVSS 9.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). Weakness: CWE-289. Affected Red Hat products: Red Hat OpenShift Dev Spaces.
Critical [CVE-2026-48491] Unauthorized access due to mutual TLS bypass
Traefik is an HTTP reverse proxy and load balancer. From 3.7.0 until 3.7.3, there is a high severity vulnerability in Traefik's domain-fronting protection (SNICheck) that allows an unauthenticated client to bypass mutual TLS enforced through wildcard router TLSOptions. When a router uses a wildcard host rule such as Host(*.example.com) with stricter TLS options (for example RequireAndVerifyClientCert), SNICheck resolves the TLS options for the HTTP Host header using exact map lookups only and never applies wildcard matching. If another permissive SNI is served on the same entrypoint, an attacker can complete the TLS handshake under the permissive options and then send an HTTP Host header targeting the wildcard-protected backend, reaching it without presenting a client certificate. This affects the regular HTTPS / HTTP-2 path and does not require HTTP/3. This vulnerability is fixed in 3.7.3. This vulnerability allows an unauthenticated client to bypass mutual Transport Layer Security (TLS) enforcement, a security measure that verifies both client and server identities. The bypass occurs due to an issue in Traefik's domain-fronting protection (SNICheck), which incorrectly processes TLS options for HTTP Host headers. As a result, an attacker can gain unauthorized access to protected backend services without presenting a required client certificate.
Critical [CVE-2026-48020] Authentication bypass in StripPrefix middleware allows unauthorized access to protected paths
Traefik is an HTTP reverse proxy and load balancer. Prior to 2.11.48, 3.6.19, and 3.7.3, there is a high severity vulnerability in Traefik's StripPrefix middleware that allows an unauthenticated attacker to bypass route-level authentication and authorization. When a public router matches on a PathPrefix rule and applies the StripPrefix middleware, a request path containing.. or its percent-encoded form %2e%2e can match the public route at routing time and then, after the prefix is stripped and the path is normalized, resolve to a path served by a separate, authenticated router. As a result, an attacker can reach protected backend paths — such as admin or internal configuration endpoints — without satisfying the authentication middleware attached to the protected router. This vulnerability is fixed in 2.11.48, 3.6.19, and 3.7.3. By crafting a request path containing '..' or its percent-encoded form, an attacker can access protected backend paths, such as administrative or internal configuration endpoints, without proper authentication. This could lead to unauthorized information disclosure or modification of sensitive settings. This is an Important authentication bypass flaw in Traefik's StripPrefix middleware, affecting Red Hat OpenShift Dev Spaces. Red Hat severity: Important — CVSS 9.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). Weakness: CWE-22.
Critical [CVE-2026-11807] websocket missing authorization allows credential theft via activation_id spoofing
A missing authorization vulnerability was found in the Event-Driven Ansible (EDA) websocket API. The /api/eda/ws/ansible-rulebook endpoint does not verify user permissions when processing Worker messages. Any authenticated user can send a forged message with an arbitrary activation_id to receive plaintext credentials associated with that activation, including OAuth tokens, vault passwords, and SSH keys. Red Hat severity: Critical — CVSS 9.6 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N). Weakness: CWE-862. Affected Red Hat products: Red Hat Ansible Automation Platform 2.5 for RHEL 8; Red Hat Ansible Automation Platform 2.5 for RHEL 9; Red Hat Ansible Automation Platform 2.6 for RHEL 9; Red Hat Ansible Automation Platform 2.5; Red Hat Ansible Automation Platform 2.6; Red Hat Ansible Automation Platform 2.7. Red Hat fixing advisory: RHSA-2026:28376, RHSA-2026:28377, RHSA-2026:28497, RHSA-2026:28492, RHSA-2026:28440.
Critical [CVE-2026-48746] Critical authentication bypass allows unauthorized API access
vLLM is an inference and serving engine for large language models (LLMs). From 0.3.0 until 0.22.0, a vulnerability in ASGI web servers and starlette's trust on those web servers enables an authentication bypass of the OpenAI API AuthenticationMiddleware. It allows to use the API without providing the configured VLLM_API_KEY or --api-key. This vulnerability is fixed in 0.22.0. CVE-2026-48746 is an authentication bypass in the vLLM OpenAI-compatible API server. A remote attacker who can reach the vLLM endpoint directly can craft a Host header so the authentication middleware checks a different URL path than the one actually dispatched, bypassing VLLM_API_KEY / --api-key protection. Successful exploitation allows unauthorized inference API access, which can result in confidentiality loss (model/prompt abuse) and availability impact (resource exhaustion). The flaw does not provide integrity compromise or arbitrary code execution. Exploitation requires vLLM API-key authentication to be enabled and the service to be exposed without an RFC-conforming reverse proxy that normalizes the Host header. Because Red Hat AI inference offerings are commonly deployed behind OpenShift Routes or similar proxies, and because the vulnerability is conditional on deployment and configuration, the overall flaw impact is rated Important rather than Critical.
Critical [CVE-2026-44727] Remote Code Execution via stored Cross-Site Scripting in nbconvert handlers
Jupyter Server is the backend for Jupyter web applications. Prior to 2.20, the nbconvert HTTP handlers in jupyter_server render user-authored notebook HTML under the Jupyter origin without a sandbox directive in their Content-Security-Policy. Combined with nbconvert.HTMLExporter's default non-sanitizing behavior, a notebook carrying an HTML payload in a display_data output triggers stored XSS with cookie access, full /api/* authority, and kernel RCE. This vulnerability is fixed in 2.20. A flaw was found in Jupyter Server. A remote attacker could exploit this to gain cookie access, full API authority, and achieve kernel Remote Code Execution (RCE). Red Hat severity: Important — CVSS 9 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H). Weakness: CWE-79. Affected Red Hat products: Red Hat Migration Toolkit for Applications 8.2; Red Hat OpenShift AI (RHOAI). Red Hat lists Red Hat OpenShift AI (RHOAI) as not affected. Red Hat fixing advisory: RHSA-2026:43038.
Critical [CVE-2026-12046] pgAdmin 4: Remote Code Execution due to missing authentication on critical functions
Two state-mutating endpoints in pgAdmin 4's SQL Editor blueprint -- DELETE /sqleditor/close/ and POST /sqleditor/initialize/sqleditor/update_connection/// -- were the only routes in the module missing the @pga_login_required decorator. Both reach a pickle.loads sink on session['gridData'][]['command_obj']: the close endpoint via close_sqleditor_session(), and update_sqleditor_connection via check_transaction_status(). In server mode these endpoints were reachable without any authenticated pgAdmin session. The defect is a missing-authentication-on-critical-function (CWE-306) wrapper around a deserialization-of-untrusted-data sink (CWE-502). Exploiting it for remote code execution requires the attacker to also forge a server-side session file whose gridData entry contains a malicious pickle payload, which in turn requires both (a) knowledge of pgAdmin's Flask SECRET_KEY (no chain to leak it is described here -- the attacker must already possess it) and (b) write access to pgAdmin's sessions/ directory on the host. Neither precondition is granted by this defect on its own.
Critical [CVE-2026-12045] pgAdmin 4: Remote code execution via prompt injection in AI Assistant
Read-only transaction bypass in the pgAdmin 4 AI Assistant allows an attacker who can influence database content that the assistant reads to execute arbitrary SQL with the privileges of the pgAdmin user's database role. The AI Assistant's execute_sql_query tool runs LLM-generated SQL inside a BEGIN TRANSACTION READ ONLY wrapper to prevent data modification. The LLM-supplied query was forwarded to the database driver without restriction to a single statement or to read-only verbs, so a multi-statement payload beginning with COMMIT, END, ROLLBACK, or ABORT terminated the read-only transaction and ran subsequent statements in autocommit mode. The trailing ROLLBACK then had no effect. Delivery is via prompt injection: an attacker who can write content into any object the AI Assistant may inspect (a row, a column value, a comment) can cause the LLM to emit the multi-statement payload as a tool call. With ordinary write privileges on the pgAdmin user's role the attacker can perform unauthorised data modification. When the pgAdmin user's role is a PostgreSQL superuser or holds pg_execute_server_program, the chain extends to remote code execution on the database server host via COPY... TO PROGRAM.
