Name of the Vulnerable Software and Affected Versions Keycloak (affected versions not specified)

Description A flaw exists in the org.keycloak.protocol.oidc component of Keycloak's Client Policies. When specific condition providers—client-type, client-roles, client-attributes, or client-scopes—are used to enforce security restrictions, the reject-ropc-grant executor is silently bypassed. This allows an unauthenticated remote attacker to obtain tokens using a Resource Owner Password Credentials (ROPC) grant, which is a flow where the user provides their credentials directly to the application to receive an access token, even if a policy is configured to block it. This bypass can result in unauthorized access and information disclosure.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
