CVE-2026-18214

Błąd w Keycloak umożliwia atakującym z innych domen Google ominięcie zabezpieczeń i uzyskanie dostępu.

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.
