CVE-2026-8688

MEDIUM

Advance Nav Menu Manager <= 1.3 - Missing Authorization to Authenticated (Subscriber+) Nav Menu Item Modification via anmm_save_menu_data AJAX Action

Title source: cna

Description

The Advance Nav Menu Manager plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to duplicate, copy, move, or publish nav_menu_item posts via wp_insert_post(), modifying the site's navigation menus without authorization.
