CVE-2026-55233 OpenResty: Buffer overflow when writing PROXY protocol v2 header to upstream

OpenResty is a high performance web platform. From 1.29.2.1 to before 1.29.2.5, an out-of-bounds write vulnerability exists in the upstream PROXY protocol v2 implementation. When OpenResty is configured to send PROXY protocol version 2 headers to upstream servers, constructing the header in the...

CVE-2026-55233

OpenResty vulnerable versions: 1.29.2.1–1.29.2.4. A PROXY protocol v2 header construction in the stream patch can cause an out-of-bounds write, crashing the worker and causing a denial of service. This affects only configurations that enable PROXY protocol v2 for upstream connections. The issue i...

undici: undici vulnerable to HTTP header injection via Set-Cookie percent-decoding

A flaw was found in undici. The cookie parser in the parseSetCookie function incorrectly decodes cookie values, which is contrary to standard specifications. This vulnerability allows an attacker-controlled upstream to inject arbitrary HTTP response headers, such as Set-Cookie, Location, or...

CVE-2026-55638

9Router is an AI router & token saver. Prior to 0.5.2, 9router protects /v1, /v1beta, /api/v1, and /api/v1beta in src/dashboardGuard.js but omits /codex before next.config.mjs rewrites /codex/ to /api/v1/responses. A remote unauthenticated attacker can send requests to /codex/ to bypass the API-k...

CVE-2026-56675 9router: Reverse proxy locality collapse allows unauthenticated access to 9router /v1 APIs

9Router is an AI router & token saver. Prior to 0.5.2, 9router treats loopback requests as trusted and allows /v1/ access without an API key, so a same-host reverse proxy that forwards public traffic to the backend through 127.0.0.1 causes src/dashboardGuard.js to misclassify external requests as...

CVE-2026-55638

9router prior to version 0.5.2 exposed an unauthenticated access path via /codex that bypassed the API-key gate due to an incomplete rewrite handling. An attacker could send requests to /codex/* and trigger upstream provider calls using operator-stored LLM provider credentials. The vulnerability ...

CVE-2026-55638 9router: Unauthenticated LLM proxy access via /codex rewrite authorization bypass

9Router is an AI router & token saver. Prior to 0.5.2, 9router protects /v1, /v1beta, /api/v1, and /api/v1beta in src/dashboardGuard.js but omits /codex before next.config.mjs rewrites /codex/ to /api/v1/responses. A remote unauthenticated attacker can send requests to /codex/ to bypass the API-k...

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...

Improper Certificate Validation

Coder is vulnerable to Improper Certificate Validation. The vulnerability is due to the AI Bridge Proxy aibridgeproxyd creating a default HTTPS transport with InsecureSkipVerify enabled when no upstream proxy is configured, which allows an on-path man-in-the-middle attacker to present a forged TL...

EUVD-2026-42721

An Improper Check for Unusual or Exceptional Conditions vulnerability in the packet forwarding engine PFE of Juniper Networks Junos OS on MX Series allows adjacent subscribers to bypass configured firewall filters. On MX Series devices with MPC10/11, LC4800/9600, and MX304 with subscribers...

Coder 2.30.x < 2.32.7 / 2.33.x < 2.33.8 / 2.34.x < 2.34.2 AI Bridge Proxy TLS Verification Bypass

The version of Coder installed on the remote host is 2.30.x prior to 2.32.7, 2.33.x prior to 2.33.8, or 2.34.x prior to 2.34.2. It is, therefore, affected by a vulnerability. The AI Bridge Proxy skips TLS certificate verification in the default configuration. The proxy created a goproxy server...

CVE-2026-59224

Open WebUI vulnerability CVE-2026-59224 affects versions prior to 0.10.0. The issue: in backend/open_webui/routers/terminals.py, the ws_terminal upstream URL is built from an unencoded session_id and appends user_id as a query parameter, enabling query injection to make the terminal backend resol...

CVE-2026-59224 Open WebUI: Terminal proxy forwards a spoofable, integrity-unbound user identity to the upstream (X-User-Id header and ws_terminal session_id query injection)

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, backend/openwebui/routers/terminals.py built the wsterminal upstream URL from an unencoded sessionid and appended userid as a query parameter, allowing query injection to make the terminal backe...

CVE-2026-45045

Fiber is an Express inspired web framework written in Go. Prior to 3.3.0 and 2.52.14, the BalancerForward proxy helper in middleware/proxy/proxy.go uses Header.Add instead of Header.Set when injecting X-Real-IP, allowing an attacker-supplied first X-Real-IP value to be forwarded to upstream serve...

CVE-2026-45045 Fiber: X-Real-IP Spoofing via Header.Add() in BalancerForward

Fiber is an Express inspired web framework written in Go. Prior to 3.3.0 and 2.52.14, the BalancerForward proxy helper in middleware/proxy/proxy.go uses Header.Add instead of Header.Set when injecting X-Real-IP, allowing an attacker-supplied first X-Real-IP value to be forwarded to upstream serve...

CVE-2026-45045

Fiber (GoFiber) is affected by a vulnerability in BalancerForward where the proxy injects X-Real-IP using Header.Add() instead of Header.Set(), allowing an attacker-supplied value to be forwarded to upstreams. Affected versions before 3.3.0 and 2.52.14 are impacted; the issue is fixed in 3.3.0 an...

CVE-2026-54423
