Project: Media Library Form API Element [1]
Version: 8.x-1.38.x-1.28.x-1.1
Date: 2023-January-18
Security risk: *Moderately critical* 13∕25
AC:None/A:User/CI:Some/II:None/E:Theoretical/TD:All [2]
Vulnerability: Information Disclosure

Affected versions: >=2.0 <2.0.6
Description: 
This module enables you to use the media library in custom forms without the
Media Library Widget.

The 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.

Solution: 
Install the latest version:

  * If you use the Media Library Form API Element module versions 2.x for
    Drupal 9 or 10, upgrade to 2.0.6 [3].
  * If you use the Media Library Form API Element module version 8.x-1.* they
    are all affected and are no longer supported. You should upgrade to 2.0.6
    [4].
