What is CVE-2026-101161?
The WP Ultimate Review plugin for WordPress, prior to version 2.4.4, is susceptible to exploitation by unauthenticated users.

This leads to a persistent denial of service, significantly impacting user experience when the review display settings of the plugin have not been previously saved, effectively rendering the site inaccessible.
