Summary: Observable Discrepancy and Observable Timing Discrepancy in Jenkins Configuration as Code Plugin

Details: Jenkins Configuration as Code Plugin prior to 1.55.1, 1.54.1, 1.53.1, and 1.47.1 does not use a constant-time comparison when checking whether two authentication tokens are equal. This could potentially allow attackers to use statistical methods to obtain a valid authentication token. Configuration as Code Plugin 1.55.1, 1.54.1, 1.53.1, and 1.47.1 now uses a constant-time comparison when validating authentication tokens.
