## What is CVE-2026-4314?

CVE-2026-4314 is a high-severity vulnerability in wpextended The Ultimate WordPress Toolkit – WP Extended, published on 22 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-269 (Improper Privilege Management)
