Project: Drupal core [1]
Date: 2023-January-18
Security risk: *Moderately critical* 12∕25
AC:None/A:User/CI:Some/II:None/E:Theoretical/TD:Default [2]
Vulnerability: Information Disclosure

Affected versions: >=8.0.0 <9.4.10 || >=9.5.0 <9.5.2 || >=10.0.0 <10.0.2
Description: 
The Media Library module does not properly check entity access in some
circumstances. This may result in users with access to edit content seeing
metadata about media items they are not authorized to access.

The vulnerability is mitigated by the fact that the inaccessible media will
only be visible to users who can already edit content that includes a media
reference field.

This advisory is not covered by Drupal Steward [3].

Solution: 
Install the latest version:

  * If you are using Drupal 10.0, update to Drupal 10.0.2 [4].
  * If you are using Drupal 9.5, update to Drupal 9.5.2 [5].
  * If you are using Drupal 9.4, update to Drupal 9.4.10 [6].

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 [7].

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