Kerentanan Missing Authorization pada redhat build of keycloak. Skor CVSS 3.1 8.1 (High) menurut NVD.

Deskripsi (NVD)

Keycloak allows users to log in using Google accounts and can be configured to only allow users from specific Google Workspace domains. A flaw was found where the token exchange feature, which allows swapping a Google token for a Keycloak token, does not check these domain restrictions. This means an attacker with a valid Google account from a different domain could bypass the security check and gain access to the Keycloak realm.
