Technical details
The vulnerability is an incorrect implementation of the authentication algorithm in the User Center login integration, affecting external user session creation. Newly created external user sessions omit the external identity field, causing subsequent requests to fail central account suspension or deletion checks until the session expires. An attacker with access to an external identity that has been subsequently suspended or deleted can continue operating until session expiration.
