Drupal core - Moderately critical - Information Disclosure - SA-CORE-2023-002

Project: Drupal core
Date: 2023-March-15
Security risk: Moderately critical 14∕25
Vulnerability: Information Disclosure
Affected versions: >=8.0.0 <9.4.12 || >=9.5.0 <9.5.5 || >=10.0.0 <10.0.5

Description

The Media module does not properly check entity access in some circumstances. This may result in users seeing thumbnails of media items they do not have access to, including for private files.

This release was coordinated with SA-CONTRIB-2023-010.

Solution

Install the latest version:

If you are using Drupal 10.0, update to Drupal 10.0.5.
If you are using Drupal 9.5, update to Drupal 9.5.5.
If you are using Drupal 9.4, update to Drupal 9.4.12.

All versions of Drupal 9 prior to 9.4.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Drupal 7 core does not include the Media Library module and therefore is not affected.
