Project: Entity Browser [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

Description: 
The Entity Browser module allows you to select entities from entity reference
fields using a custom entity browser widget.

Entity Browser does not properly check entity access in some circumstances.
This may result in users with access to edit content seeing metadata about
entities they are not authorized to access.

The vulnerability is mitigated by the fact that the inaccessible entities
will only be visible to users who can already edit content using Entity
Browser.

Solution: 
Install the latest version:

   * If you use the Entity Browser module for Drupal 9 or 10, upgrade to 
Entity
     Browser 8.x-2.9 [3].
