CVE-2026-63771

Adminer before 5.4.3 contains a cookie injection vulnerability that allows attackers to manipulate cookie attributes by injecting arbitrary values through the unsanitized X-Forwarded-Prefix HTTP header used in Set-Cookie path attributes. Attackers can exploit a misconfigured reverse proxy to...

CVE-2026-55652

Wekan prior to v9.46 is vulnerable to a header-login bypass: the server trusts X-Forwarded-For via HEADER_LOGIN_TRUSTED_IPS in getRequestIp(), allowing unauthenticated users to request a login for any username and obtain a meteor_login_token (including admin), enabling full account takeover. The ...

GHSA-PQG7-V6WH-3PFP TsDProxy: X-Forwarded-For header injection allows IP spoofing in proxied requests to backend services

Description The HTTP reverse proxy handler in tsdproxy does not strip the X-Forwarded-For or X-Real-IP header from incoming requests before calling r.SetXForwarded. This allows an authenticated Tailscale user to inject arbitrary X-Forwarded-For values that are forwarded verbatim to backend...

CVE-2026-9561

Eclipse Kura versions prior to 5.6.2 trust the client-supplied X-Forwarded-For HTTP header as the authoritative source of the client IP address in audit log entries. The org.eclipse.kura.web2 Web Console and org.eclipse.kura.rest.provider REST API components use this header as the primary IP sour...

GHSA-4CHG-4752-W88R NukeViet: Pre-authentication SSRF via X-Forwarded-Host

Summary An unauthenticated attacker can coerce the server into issuing HTTP requests to an attacker-chosen host by spoofing the X Forwarded-Host and X-Forwarded-Proto request headers. The forwarded host is used, without validation, to build the URL that serverinfoupdate fetches with cURL, resulti...

CVE-2026-55501 9router: Login brute-force protection bypass via spoofed X-Forwarded-For header

9Router is an AI router & token saver. Prior to 0.4.80, the dashboard login rate limiter in src/lib/auth/loginLimiter.js derives the client identity from the attacker-controlled X-Forwarded-For HTTP header, and src/app/api/auth/login/route.js uses that spoofable value for checkLock and recordFail...

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...

PT-2026-56988

Name of the Vulnerable Software and Affected Versions Hermes WebUI versions prior to 0.51.307 Description An authentication bypass exists that allows unauthenticated remote attackers to circumvent local-origin IP restrictions on onboarding endpoints. This is achieved by supplying a spoofed...

CVE-2026-59897

Hono is a Web application framework that provides support for any JavaScript runtime. From 4.3.3 before 4.12.27, the AWS API Gateway v1 adapter can drop a distinct repeated request header value because it de-duplicates values using a substring comparison instead of an exact match, so middleware o...

CVE-2026-59897 Hono: API Gateway v1 adapter can drop a distinct repeated request header value during de-duplication

Hono is a Web application framework that provides support for any JavaScript runtime. From 4.3.3 before 4.12.27, the AWS API Gateway v1 adapter can drop a distinct repeated request header value because it de-duplicates values using a substring comparison instead of an exact match, so middleware o...

CVE-2026-55430

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...

CVE-2026-55430

Coder's workspace app (github.com/coder/coder) prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 trusts X-Forwarded-Host for routing because no middleware strips it before routing and httpapi.RequestHost() prefers that header over Host. This enables cross-app data access when subdomain (wildca...

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

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...

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...
