Description
ZITADEL is an open source identity management platform. Prior to version 4.16.0, a bug in how ZITADEL updates permissions when multiple project roles are deleted at the same time can cause some user permissions to be missed. This issue specifically affects User Grants on Granted Projects (projects shared between different organizations), potentially allowing users to keep access rights that were supposed to be completely removed. This issue has been fully resolved in version 4.16.0. There are no configuration workarounds. Upgrading to a patched version is the only way to trigger the automatic cleanup migration. Those who cannot upgrade immediately should manually review user permissions specifically for Granted Projects where multiple roles were recently deleted.
