Description Andrej Nemec 2016-02-25 11:30:05 UTC

The following flaw was found in Jenkins:

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