Upstream source description

The Optima Express IDX WordPress plugin before 8.7.6 does not perform any authorisation check on one of its AJAX actions that is available to logged-out users, allowing unauthenticated attackers to force the creation of a fixed author-role account and to repeatedly rotate its application password on any connected install.
