What is CVE-2026-96897?

The Optima Express IDX plugin for WordPress prior to version 8.7.6 has a serious issue where it fails to implement authorization checks for certain AJAX actions accessible to users who are not logged in. This could allow unauthorized attackers to create an account with fixed author-role privileges and change its application password on any connected WordPress installation, potentially compromising the security of the site.

Affected Version(s)

Optima Express IDX 8.5.0 < 8.7.6

Exploit Proof of Concept (PoC)
