jenkins is vulnerable to timing attack. A remote attacker is able to bypass CSRF protection mechanism through a brute-force approach of analyzing server response time to guess the value of CSRF tokens. This is due to the verification of the CSRF tokens not being performed using a constant-time algorithm.
