Vikunja has a Rate-Limit Bypass for Unauthenticated Users via Spoofed Headers

Summary Unauthenticated users are able to bypass the application's built-in rate-limits by spoofing the X-Forwarded-For or X-Real-IP headers due to the rate-limit relying on the value of echo.Context.RealIP. Details In the first file below, the rate-limit for unauthenticated users can be observed...

CVE-2026-29054

CVE-2026-29054 (Traefik) affects Traefik HTTP reverse proxy/load balancer from versions 2.11.9–2.11.37 and 3.1.3–3.6.8. The issue arises when Traefik processes HTTP/1.1 requests: the protection that prevents removal of Traefik-managed X-Forwarded headers via the Connection header compares tokens ...

CVE-2026-29054 Traefik: lowercase `Connection` tokens can delete traefik-managed forwarded identity headers (for example, `X-Real-Ip`)

Traefik is an HTTP reverse proxy and load balancer. From version 2.11.9 to 2.11.37 and from version 3.1.3 to 3.6.8, there is a potential vulnerability in Traefik managing the Connection header with X-Forwarded headers. When Traefik processes HTTP/1.1 requests, the protection put in place to preve...

Brute Force

Overview Affected versions of this package are vulnerable to Brute Force via the authentication rate limiting process. An attacker can bypass authentication rate limiting by forging the X-Real-IP header, allowing unlimited authentication attempts from a single source. Remediation Upgrade...

CVE-2026-27981

HomeBox is a home inventory and organization system. Prior to 0.24.0, the authentication rate limiter authRateLimiter tracks failed attempts per client IP. It determines the client IP by reading, 1. X-Real-IP header, 2. First entry of X-Forwarded-For header, and 3. r.RemoteAddr TCP connection...

CVE-2026-27981

HomeBox vulnerability CVE-2026-27981 allows an attacker to bypass authentication rate limiting by spoofing client IPs via X-Real-IP and manipulating X-Forwarded-For, since the authRateLimiter reads these headers and r.RemoteAddr unconditionally, with RealIP middleware overwriting the remote addre...
