GHSA-M547-HP4W-J6JX 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-2026-29794

Vikunja (open-source self-hosted task management) before version 2.2.0 is affected by a rate-limit bypass vulnerability. The issue arises because rate-limiting is enforced using (echo.Context).RealIP, and unauthenticated requests can spoof headers X-Forwarded-For or X-Real-IP to bypass limits. Th...
