Description Andrej Nemec 2016-02-25 11:31:18 UTC

The following flaw was found in Jenkins:

The verification of user-provided CSRF crumbs with the expected value did not use a constant-time comparison algorithm, potentially allowing attackers to use statistical methods to determine valid CSRF crumbs using brute-force methods.
