## Affected

- Unknown WP Ultimate Review: fixed in 2.4.4

## 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.
