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 properly neutralise a script value submitted through one of its REST endpoints before storing it and echoing it into the document head when the post is rendered, allowing users with a role as low as author to perform Stored Cross-Site Scripting attacks.
