CVE-2026-101160: CWE-400 Uncontrolled Resource Consumption in WP Ultimate Review
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.
AI Analysis
Technical Summary
CVE-2026-101160 is an uncontrolled resource consumption vulnerability (CWE-400) in the WP Ultimate Review plugin for WordPress. Versions prior to 2.4.4 fail to validate that review ratings submitted by users are numeric before storing and using them in numeric operations. This allows unauthenticated attackers to submit malformed ratings that cause fatal errors when rendering reviews, leading to a persistent denial of service affecting all visitors until the problematic review is deleted.
Potential Impact
Unauthenticated users can cause the plugin to crash with a fatal error by submitting non-numeric review ratings. This results in a persistent denial of service affecting all visitors to the reviewed content until the malicious review is removed. The disruption impacts availability of the review feature and potentially the website's user experience.
Mitigation Recommendations
Upgrade the WP Ultimate Review plugin to version 2.4.4 or later, where this validation issue is fixed. Until then, monitor and remove any malformed reviews causing fatal errors. No official patch link is provided in the data, but the version 2.4.4 update addresses the vulnerability.
