CVE-2024-47807Network attack vector

Administrator access via unchecked token issuer

Published Oct 2, 2024 · Updated Oct 2, 2024

Authentication bypass in OpenId Connect Authentication Plugin 4.354.v321ce67a_1de8 and earlier allows remote attackers to gain administrator access. The authentication flow accepts an ID Token without checking its iss claim against the configured or discovered identity-provider issuer. Reachability requires Jenkins to use the plugin as its security realm; successful subversion can assign administrator access, while the exact token-acquisition path is undisclosed.
