Summary

Cotonti through 1.0.0 derives password recovery validation tokens from md5(microtime()) in users.passrecover.php, creating a predictable token space of approximately one million values per second. Unauthenticated attackers can read the server Date header, precompute candidate tokens within a narrow time window, and probe them against the passrecover authentication endpoint to reset any account password including administrators.
