Project: The Better Mega Menu [1] Date: 2021-September-22 Security risk: *Moderately critical* 14∕25 AC:Basic/A:User/CI:Some/II:Some/E:Proof/TD:Default [2] Vulnerability: Access bypass

Description:  This module provides an admin interface for creating drop down menus that combine Drupal menu items with rich media content.

This module has a vulnerability whereby users can select blocks as a menu item they don't have permission to view.

The vulnerability is mitigated by the fact that it can only be exploited by an attacker with the "Administer TB Mega Menu" permission.

Solution:  Install the latest version:

* If you use the TB Mega Menu module for Drupal 8.x, upgrade to TB MegaMenu 8.x-1.4 [3]
