Technical details
The `/api/auth/login` endpoint in FileBrowser does not implement rate limiting, account lockout, or progressive backoff for failed authentication attempts. An attacker can perform high-frequency automated login attempts over the network without authentication. This vulnerability is exacerbated by a weak default password policy (minimum 5 characters) and can be combined with username enumeration timing attacks to identify and compromise valid accounts. The issue was addressed in version 0.0.0-20260522161427-fa5abc8c67f3a.
