Project: The Better Mega Menu [1]
Date: 2021-September-22
Security risk: *Moderately critical* 12∕25
AC:Complex/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross Site Scripting, Information Disclosure, Multiple
vulnerabilities

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

The module does not sanitize values for CSS properties that are added by
admins and rendered on the front-end, allowing attackers to inject malicious
code into the front-end markup.

This vulnerability is mitigated by the fact that it can only be exploited by
an attacker with permissions to administer TB Mega Menu, or a sophisticated
anonymous user using a site-specific attack that exploits the Cross Site
Request Forgery vulnerability that is fixed by this same release.

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]
