Kerentanan Incorrect Privilege Assignment pada redhat build of keycloak. Skor CVSS 3.1 6.5 (Medium) menurut redhat.com.

Deskripsi (NVD)

A flaw was found in the Identity Provider (IdP) mapper component of Keycloak, which is used to manage how user information from external services is mapped to Keycloak users. An administrator with limited permissions to manage identity providers can exploit this flaw by creating a "Hardcoded Role" mapper that assigns high-level administrative roles (like realm-admin) to themselves or others. This allows a restricted administrator to bypass security checks and gain full control over the entire realm.
