A Media Library access-checking flaw could expose metadata about media items to users who can edit content containing a media reference field. Update Drupal core to a listed fixed version.

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.

Drupal core

Fixed versions: Drupal 10.0.2, Drupal 9.5.2, Drupal 9.4.10

Prerequisites: users who can already edit content that includes a media reference field
