When internal roles are removed from a user within the WSO2 product, the system fails to invalidate any previously issued authentication tokens associated with that user. This vulnerability could allow users to retain their previous access privileges even after their roles have been revoked. As a result, a user can continue to perform unauthorized actions or access restricted resources until the expired tokens naturally expire.
