Security advisories: Drupal core – Moderately critical – Access bypass – SA-CORE-2019-011

Project: 
Version: 
8.8.x-dev
8.7.x-dev
Date: 
2019-December-18
Vulnerability: 
Access bypass
Description: 

The Media Library module has a security vulnerability whereby it doesn’t sufficiently restrict access to media items in certain configurations.

Solution: 
  • If you are using Drupal 8.7.x, you should upgrade to Drupal 8.7.11.
  • If you are using Drupal 8.8.x, you should upgrade to Drupal 8.8.1.

Versions of Drupal 8 prior to 8.7.x are end-of-life and do not receive security coverage.

Alternatively, you may mitigate this vulnerability by unchecking the “Enable advanced UI” checkbox on /admin/config/media/media-library. (This mitigation is not available in 8.7.x.)
