Upstream source description

CRMEB through 6.0.0 fails to validate message ownership in the edit_message handler of MessageSystemController.php, allowing authenticated users to modify arbitrary system inbox messages. Attackers can update any message's columns including is_del, look, and uid to delete, mark read, or reassign victim notifications without authorization.
