CVE-2026-3772

Description

The WP Editor plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2.9.2. This is due to missing nonce verification in the 'add_plugins_page' and 'add_themes_page' functions. This makes it possible for unauthenticated attackers to overwrite arbitrary plugin and theme PHP files with attacker-controlled code via a forged request, granted they can trick a site administrator into performing an action such as clicking a link.
