CVE-2026-8688

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

View on CVE.org
Published Jun 24, 2026 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed
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.

Analysis

AI-generated

Technical impact

The Advance Nav Menu Manager plugin for WordPress contains an authorization bypass that allows any authenticated user with subscriber-level permissions or higher to duplicate, copy, move, or publish navigation menu items. The vulnerability arises because the plugin fails to verify whether the user is authorized to perform the anmm_save_menu_data action, which internally calls wp_insert_post() to create or modify nav_menu_item posts. This flaw permits attackers to alter the site’s navigation structure without proper approval, potentially enabling defacement or redirecting visitors to malicious destinations.

Affected Systems

Vendors: KrishaWeb. Product: Advance Nav Menu Manager plugin for WordPress, versions up to and including 1.3. No specific patch notes are provided for newer releases releases through v1.3.

Risk and Exploitability

The CVSS score of 4.3 indicates moderate severity and the EPSS score is not available, suggesting low additional context. The vulnerability is not listed in the CISA KEV catalog. Attackers must already have authenticated access as a subscriber or higher, but once authenticated they can freely alter navigation menus, which could affect site usability and trust.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update the Advance Nav Menu Manager plugin to the latest release that addresses this authorization bypass
  • If an immediate update is not possible, remove or reduce subscriber-level permissions that allow navigation menu editing, or configure WordPress role capabilities to restrict this capability to administrators
  • Regularly backup the database and monitor wp_posts entries for unauthorized nav_menu_item posts to detect unauthorized changes promptly
