CVE-2026-55641 9router: Unauthenticated `/v1` proxy access via `Host`-header spoofing → open AI relay + SSRF

9Router is an AI router & token saver. Prior to 0.5.2, 9router determines whether a /v1 LLM proxy request is local by reading the client-controlled Host header, allowing a remote unauthenticated attacker to send Host: localhost and bypass API-key authentication. In the default configuration, this...

CVE-2026-55641

9router (affected component: /v1 LLM proxy logic) had an unauthenticated bypass due to client-controlled Host header processing before version 0.5.2. This allowed a remote attacker to craft Host: localhost to bypass API-key checks, potentially enabling upstream provider calls with stored credenti...

CVE-2026-58122 Hermes WebUI < 0.51.307 Authentication Bypass via X-Forwarded-For Header Spoofing

Hermes WebUI before 0.51.307 contains an authentication bypass vulnerability that allows unauthenticated remote attackers to circumvent local-origin IP restrictions on onboarding endpoints by supplying a spoofed X-Forwarded-For header with a loopback address. Attackers can exploit this bypass to...

CVE-2026-58122 Hermes WebUI < 0.51.307 Authentication Bypass via X-Forwarded-For Header Spoofing

CVE-2026-58122

CVE-2026-58122 affects Hermes WebUI prior to 0.51.307. An authentication bypass allows unauthenticated remote attackers to circumvent local-origin IP restrictions on onboarding endpoints by spoofing X-Forwarded-For with a loopback address. Exploitation enables server-side request forgery against ...

netty-codec-redis: Netty: Denial of Service via malicious Redis array header

A flaw was found in Netty, a network application framework. The RedisArrayAggregator component pre-allocates memory based on the declared element count in a Redis array header. A remote attacker can exploit this by sending a small, malicious Redis array header that claims a huge initial capacity,...

EUVD-2026-42136

Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, the workspace app proxy resolves the target app from httpapi.RequestHost which prefers the X-Forwarded-Host header over the real Host header. No middleware...

PYSEC-2026-1553 Litestar X-Forwarded-For Header Spoofing Vulnerability Enables Rate Limit Evasion

While testing Litestar's RateLimitMiddleware, I discovered that rate limits can be completely bypassed by manipulating the X-Forwarded-For header. This renders IP-based rate limiting ineffective against determined attackers. The Problem Litestar's RateLimitMiddleware uses cachekeyfromrequest to...

CVE-2026-34198 Coolify: Password reset link poisoning via X-Forwarded-Host header spoofing

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, the TrustProxies middleware trusts all proxies $proxies = '', accepting X-Forwarded-Host from any source. The TrustHosts middleware, intended to prevent host header attacks...

CVE-2026-54764 ForwardAuth middleware leaks X-Forwarded-Port spoofing via untrusted X-Forwarded-Proto when trustForwardHeader=false

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 t...
