CVE-2026-84476: Authentication Bypass by Spoofing

WWBN AVideo fails to validate trusted proxies before accepting X-Real-IP and X-Forwarded-For headers, allowing attackers to spoof the client address used by enforceRateLimit. Attackers can rotate the header value per request to bypass login rate limiting and perform unlimited credential guessing...

CVE-2026-45045

A flaw was found in the GoFiber web framework's BalancerForward proxy helper. This vulnerability allows a remote attacker to spoof their IP address by manipulating the X-Real-IP header. Because the Header.Add function is used instead of Header.Set, an attacker-supplied X-Real-IP value is forwarde...

CVE-2026-72816

go-chi/chi through 5.2.1 contains an IP spoofing vulnerability in the RealIP middleware middleware/realip.go. The realIP function reads client-controlled headers True-Client-IP, X-Real-IP, and X-Forwarded-For and overwrites r.RemoteAddr without verifying that the request originated from a trusted...

Vaultwarden unconditionally trusts the X-Real-IP header, enabling rate-limit bypass and audit IP spoofing

Vaultwarden Unconditional Trust in the X-Real-IP Request Header Leading to Rate-Limit Bypass and Audit IP Spoofing Overview Vaultwarden supports reading the client IP from a configurable HTTP request header IPHEADER, default X-Real-IP for rate limiting of login/2FA and the admin panel, as well as...

CVE-2026-64619

FileCodeBox prior to 2.4 is affected by a rate-limit bypass in the IPRateLimit component. An unauthenticated attacker can spoof X-Real-IP and X-Forwarded-For headers without verifying the trusted reverse proxy origin, sending unique IP values per request to enumerate all share codes and access ot...

PT-2026-61697

FileCodeBox before 2.4 contains a rate-limit bypass vulnerability in the IPRateLimit class that allows unauthenticated attackers to circumvent request throttling by supplying attacker-controlled X-Real-IP and X-Forwarded-For headers without verification of trusted reverse proxy origin. Attackers...

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...
