Technical details

The SetClientMetadata RPC endpoint performs an insufficient permission check, allowing users with LABEL_CLIENTS permission to write to server metadata rather than enforcing an admin-only restriction. Server metadata typically stores site-wide configuration, and the vulnerability permits unauthorized elevation of privilege through a permissions bypass on a metadata update API call.
