Overview

CVE-2026-4314 is a high-severity vulnerability. It was published on March 22, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

The 'The Ultimate WordPress Toolkit – WP Extended' plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.2.4. This is due to the `isDashboardOrProfileRequest()` method in the Menu Editor module using an insecure `strpos()` check against `$_SERVER['REQUEST_URI']` to determine if a request targets the dashboard or profile page. The `grantVirtualCaps()` method, which is hooked into the `user_has_cap` filter, grants elevated capabilities including `manage_options` when this check returns true. This makes it possible for authenticated attackers, with Subscriber-level access and above, to gain administrative capabilities by appending a crafted query parameter to any admin URL, allowing them to update arbitrary WordPress options and ultimately create new Administrator accounts.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
