CVE-2026-84476 WWBN AVideo Authentication Bypass via X-Real-IP Header

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-2026-84476

WWBN AVideo contains an authentication bypass flaw in its login rate limiting mechanism. The application fails to validate trusted proxies before accepting X-Real-IP and X-Forwarded-For headers, which are consumed by the enforceRateLimit() function. An unauthenticated, network-based attacker can ...

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...

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-2026-64619: Use of Less Trusted Source

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...

Kirby is an open-source content management system. Prior to 4.9.4 and from 5.4.4, Kirby sites with no configured user accounts that run on publicly accessible servers behind a reverse proxy setting the Forwarded, X-Client-IP, or X-Real-IP request header could allow remote attackers to install the...

GHSA-GCFQ-8GQF-4876 GoFiber Vulnerable to X-Real-IP Spoofing via Header.Add() in BalancerForward

Summary The BalancerForward proxy helper in GoFiber uses Header.Add instead of Header.Set when injecting the X-Real-IP header. This appends the real client IP as a second header value rather than replacing any attacker-supplied value. Upstream servers that read the first X-Real-IP header nginx,...
