Summary
Capgo before 12.128.2 contains a privilege escalation vulnerability where demoted super_admin users retain access to delete_non_compliant_bundles and count_non_compliant_bundles RPCs due to stale org_users.user_right column not being cleared during role binding deletion. Attackers can exploit this by maintaining a previously granted super_admin role to enumerate and bulk delete non-compliant bundles across the entire organization indefinitely.
