Description
Distributor before 2.3.2 contains a missing authorization vulnerability that allows Contributor-level users to invoke external connection AJAX actions intended for manage_options users. Attackers can call dt_verify_external_connection with a chosen endpointId and url to send stored connection credentials to attacker-controlled servers, or abuse dt_begin_authorization to create connections.
