Summary

Duplicate Advisory: Vikunja: Every /api/v2 pre-auth endpoint is unthrottled on a stock install while its /api/v1 twin is rate limited

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-6rvj-qwjf-3m4q. This link is maintained to preserve external references.

Original Description

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.
