What is CVE-2026-101160?

The WP Ultimate Review WordPress plugin, prior to version 2.4.4, contains a significant input validation vulnerability. It fails to ensure that user-submitted review ratings are numeric before processing them. This oversight allows unauthenticated users to submit malicious input, potentially causing the reviewed content to render incorrectly and resulting in a persistent denial of service. Visitors to the site may encounter fatal errors until the problematic review is removed, emphasizing the critical need for secure coding practices in plugin development.
