Capgo before 12.128.2 contains an authorization flaw in transfer_app() that fails to update deploy_history.owner_org when transferring applications between organizations. Attackers can exploit this omission to retain unauthorized access to deployment history records in the source organization or cause the destination organization to lose access to transferred application deployment records.
