Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins Credentials plugin versions 1380.va_435002fa_924 and earlier, excluding 1371.1373.v4eb_fa_b_7161e9, do not redact encrypted values of SecretBytes-type credentials such as certificate and secret file credentials when item config.xml is accessed via the REST API or CLI. An attacker with Item/Extended Read permission can view these encrypted values. Upgrade to Credentials plugin 1381.v2c3a or 1371.1373.v4eb, noting that the fix is only effective on Jenkins 2.479 and newer or LTS 2.462.3 and newer.
