Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection via the oidc-claims-extension.groovy script when the claims_parameter_supported parameter is enabled. An attacker can inject arbitrary values into claims returned in id_token or user_info by supplying a crafted JSON file in the claims parameter, potentially impersonating other users or manipulating identity data.
