CVE-2024-46999: User Grant Deactivation not Working in Zitadel
Impact
ZITADEL's user grants deactivation mechanism did not work correctly. Deactivated user grants were still provided in token, which could lead to unauthorized access to applications and resources. Additionally, the management and auth API always returned the state as active or did not provide any information about the state.
