GHSA-fpj7-9xm6-8hgr Observable Discrepancy and Observable Timing Discrepancy in Jenkins Configuration as Code Plugin

• Maven io.jenkins:configuration-as-code: >= 1.55, < 1.55.1 → fixed in 1.55.1 • Maven io.jenkins:configuration-as-code: >= 1.54, < 1.54.1 → fixed in 1.54.1 • Maven io.jenkins:configuration-as-code: >= 1.48, < 1.53.1 → fixed in 1.53.1 • Maven io.jenkins:configuration-as-code: < 1.47.1 → fixed in 1.47.1

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.
