CVE-2026-91972

8.7 highEPSS 0.6%

High (8.7). EPSS 0.6% chance of exploitation in the next 30 days. Fixed in code.vikunja.io/api 2.6.0.

Vikunja versions before 2.6.0 fail to apply rate limiting to /api/v2 public authentication endpoints including login, register, password-reset, and OAuth token routes. Remote unauthenticated attackers can perform unbounded credential guessing, account enumeration, and password-reset flooding attacks without throttling restrictions.
