AI-suggested

Upgrade affected ZITADEL instances to version 4.16.0 or later. This update fixes the role revocation logic and includes an automatic database migration that scans and corrects any user permissions left behind by the bug. There are no configuration workarounds. If immediate upgrade is not possible, manually review and adjust user permissions on Granted Projects where multiple roles were deleted to ensure no unintended permissions remain.

Description

ZITADEL versions prior to 4.16.0 contain a bug in the role revocation process for User Grants on Granted Projects when multiple roles are deleted simultaneously. This bug can cause some user permissions to be missed during cleanup, potentially allowing users to retain elevated access that should have been removed. The issue does not affect direct project roles or global organization roles. The vulnerability has been fixed in version 4.16.0 with an update that includes an automatic database migration to correct any leftover permissions. No configuration workarounds exist; upgrading is the recommended remediation.
