Project: Media Library Block [1]
Date: 2023-January-18
Security risk: *Moderately critical* 14∕25
AC:None/A:None/CI:Some/II:None/E:Theoretical/TD:Default [2]
Vulnerability: Information Disclosure

Affected versions: >=1.0 <1.0.4
Description: 
The Media Library Block module allows you to render a media entity in a
block.

The module does not properly check media access in some circumstances. This
may result in unauthorized users (including anonymous users) seeing media
items they are not authorized to access if a block containing a restricted
media item is placed on the page.

Administrators may mitigate this vulnerability by removing blocks referencing
media items that have access restrictions.

Solution: 
Install the latest version:

   * If you use the Media Library Block module for Drupal 9 or 10, upgrade to
     Media Library Block 1.0.4 [3].
