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...

Brute Force

Overview 9router is a 9Router CLI - Start and manage 9Router server Affected versions of this package are vulnerable to Brute Force in the authentication process. An attacker can gain unauthorized access to administrative functions by sending repeated login attempts with different values in the...

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,...

GHSA-H5GM-X9WR-VHCM Craft Commerce: Coupon Code Brute-Force via Rate Limit Bypass

Summary The CartController defines a RateLimiter behavior that is only activated when the 'number' POST/GET parameter is explicitly provided. Details When an attacker submits coupon codes against the session-based cart without passing a 'number' parameter, no rate limiting is applied. This allows...
