Date: January 22, 2025

Jenkins OpenId Connect Authentication Plugin 4.452.v2849b_d3945fa_ and earlier, except 4.438.440.v3f5f201de5dc, treats usernames as case-insensitive, allowing attackers on Jenkins instances configured with a case-sensitive OpenID Connect provider to log in as any user by providing a username that differs only in letter case, potentially gaining administrator access to Jenkins.
