Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins OpenId Connect Authentication Plugin (org.jenkins-ci.plugins:oic-auth) versions before 4.229.vf736b store the password of a local user account used as an anti-lockout feature in a recoverable format. An attacker with access to the Jenkins controller file system could recover the plain text password and likely gain administrator access to Jenkins. Upgrade to version 4.229.vf736b or later.
