AI-Generated

A critical vulnerability exists in systems using a federated OpenID Connect (OIDC) provider, allowing authenticated users to gain unauthorized access to the uaa.admin scope, even when restricted by the externalGroupsWhitelist configuration. This occurs when the OIDC identity provider employs groupMappingMode: AS_SCOPES with a wildcard entry, potentially leading to privilege escalation. Organizations utilizing OIDC for user authentication should prioritize addressing this issue to mitigate the risk of unauthorized access to sensitive administrative functions.
