CVE-2024-47807
Jenkins OpenId Connect Authentication Plugin lacks issuer claim validation
Impact
Jenkins OpenId Connect Authentication Plugin 4.354.v321ce67a_1de8 and earlier does not check the `iss` (Issuer) claim of an ID Token during its authentication flow, a value that identifies the Originating Party (IdP). This vulnerability may allow attackers to subvert the authentication flow, potentially gaining administrator access to Jenkins. OpenId Connect Authentication Plugin 4.355.v3a_fb_fca_b_96d4 checks the `iss` (Issuer) claim of an ID Token during its authentication flow when the Issuer is known.
