What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

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.
