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 WP Ultimate Review WordPress plugin before 2.4.4 does not validate that a submitted review rating is numeric before storing it and later using it in numeric operations when rendering reviews, allowing unauthenticated users to make the reviewed content fail with a fatal error for all visitors until the review is removed (a persistent denial of service), when user reviews are enabled.
