CVE-2026-55233

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: 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...

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-2026-45045

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 (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

A malicious user with access to deploy a node directly via Ironic can specify the IPMI sendraw deployment step with a malicious payload and send commands to that nodes' BMC. IPMI sendraw capability is exposed multiple ways, including via VendorPassthru interfaces restricted to system admin and...

CVE-2026-55436

The CVE-2026-55436 issue affects Coder’s AI Bridge Proxy (aibridgeproxyd) in versions prior to 2.32.7, 2.33.8, and 2.34.2. The root cause is that the proxy’s default goproxy transport uses InsecureSkipVerify: true and only switches to a secure transport if an upstream proxy is configured; thus ou...

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...

GHSA-84RM-42XW-MX52 Coder's AI Bridge Proxy skips TLS certificate verification in default configuration

Summary The AI Bridge Proxy aibridgeproxyd created a goproxy server whose default transport set InsecureSkipVerify: true and only assigned a secure transport when an upstream proxy was configured. In the default configuration no upstream proxy, outbound HTTPS to the Coder access URL accepted any...

GHSA-5G4W-3VW9-478W Coder's subdomain workspace app routing trusts unauthenticated X-Forwarded-Host header, enabling cross-app data access

Summary 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 strips X-Forwarded-Host before routing and the header is not browser-forbidden so client-side JavaScript can set it on fetch calls...
