High [CVE-2026-46592] Remote attacker can execute unintended operations via header manipulation
Remote attacker can execute unintended operations via header manipulation. Red Hat rates this important (CVSS 7.5). Weakness: CWE-639.
High [CVE-2026-46584] Credential exposure and information disclosure via improper input validation of mail headers
Credential exposure and information disclosure via improper input validation of mail headers. Red Hat rates this moderate (CVSS 7.5). Weakness: CWE-918.
High [CVE-2026-40859] Apache Camel (camel-vertx-http): Remote Code Execution via Deserialization of Untrusted Data
Apache Camel (camel-vertx-http): Remote Code Execution via Deserialization of Untrusted Data. Red Hat rates this important (CVSS 8.1). Weakness: CWE-502.
Medium [CVE-2026-59710] Stored Cross-Site Scripting via unescaped table header ID attributes in markdown
Stored Cross-Site Scripting via unescaped table header ID attributes in markdown. Red Hat rates this moderate (CVSS 6.1). Weakness: CWE-79.
Medium [CVE-2026-59711] Cross-site scripting via unescaped metadata title allows arbitrary code execution
Cross-site scripting via unescaped metadata title allows arbitrary code execution. Red Hat rates this moderate (CVSS 6.1). Weakness: CWE-79.
Medium [CVE-2026-54764] Authorization bypass in ForwardAuth middleware via forged X-Forwarded-Port
Traefik is an HTTP reverse proxy and load balancer. Prior to v2.11.51, v3.6.22, and v3.7.6, Traefik's ForwardAuth middleware, even when configured with trustForwardHeader: false, derives the X-Forwarded-Port header sent to the authentication service from the original incoming request instead of the sanitized forwarded request. As a result, an unauthenticated remote attacker can inject an X-Forwarded-Proto: https header over a plain HTTP connection and cause Traefik to forward X-Forwarded-Port: 443 to the authentication service, bypassing port-based authorization checks. This issue is fixed in versions v2.11.51, v3.6.22, and v3.7.6. This bypasses port-based authorization checks, potentially granting unauthorized access. Moderate: A flaw in Traefik's ForwardAuth middleware, as used in Red Hat OpenShift Dev Spaces, allows an unauthenticated remote attacker to bypass port-based authorization. Red Hat severity: Moderate — CVSS 5.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N). Weakness: CWE-348. Affected Red Hat products: Red Hat OpenShift Dev Spaces. Red Hat does not currently list a fixing RHSA for this CVE.
Medium [CVE-2026-55514] Denial of Service via crafted prompt in /v1/completions request
Denial of Service via crafted prompt in /v1/completions request. Red Hat rates this moderate (CVSS 6.5). Weakness: CWE-617.
Medium [CVE-2026-55646] Denial of Service due to excessive memory allocation via oversized audio file uploads
Denial of Service due to excessive memory allocation via oversized audio file uploads. Red Hat rates this moderate (CVSS 6.5). Weakness: CWE-770.
Medium [CVE-2026-54291] Man-in-the-middle protection bypass via SCRAM-SHA-256-PLUS downgrade
pgjdbc is an open source postgresql JDBC Driver. In releases 42.7.4 through 42.7.11, channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle protection the setting is meant to guarantee. An attacker who can intercept the TLS connection can trigger the downgrade with a certificate whose signature algorithm has no tls-server-end-point channel-binding hash, because the bundled com.ongres.scram:scram-client returns an empty byte array instead of failing and pgJDBC ScramAuthenticator checks only that the server advertised a PLUS mechanism, without rejecting the empty binding or checking that the negotiated mechanism uses channel binding. This issue is fixed in version 42.7.12. A remote attacker who can intercept a TLS (Transport Layer Security) connection can silently downgrade connections configured to require channel binding from SCRAM-SHA-256-PLUS to plain SCRAM-SHA-256. This downgrade bypasses the intended man-in-the-middle protection, allowing the attacker to potentially intercept or alter sensitive communication. The vulnerability occurs because the system fails to properly validate the channel binding when a specific type of certificate is used. Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N). Weakness: CWE-940.
