The record
The authentication endpoint `POST /auth/token` in `yamcs-core` lacks any form of rate limiting, account lockout, or failed attempt throttling. As a result, an unauthenticated remote attacker can perform unlimited password guessing attempts against any user account. This missing rate limiting vulnerability (CWE-307) significantly increases the risk of successful brute-force attacks.
