Technical details

The GET /account/contact/get/{id} endpoint in CustomerContactController fails to enforce organization, owner, or data-scope checks before returning contact details. An authenticated attacker with ordinary contact read permissions can enumerate contact IDs and retrieve sensitive contact information belonging to other users or organizations. This is a broken object-level authorization flaw requiring only valid authentication and baseline read permission.
