Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Jenkins OpenId Connect Authentication Plugin versions 4.354.v321ce67a_1de8 and earlier do not check the aud (Audience) claim of ID Tokens during authentication, so tokens issued for a different client may be accepted. An attacker who can obtain such a token may be able to subvert the authentication flow and potentially gain administrator access to Jenkins. Upgrade to version 4.355.v3a_fb_fca_b_96d4 or later, which validates the audience claim.
