Project: Drupal core [1]
Date: 2020-September-16
Security risk: *Moderately critical* 12∕25
AC:None/A:User/CI:Some/II:None/E:Theoretical/TD:Default [2]
Vulnerability: Information disclosure

CVE IDs: CVE-2020-13670
Description: 
A vulnerability exists in the File module which allows an attacker to gain
access to the file metadata of a permanent private file that they do not have
access to by guessing the ID of the file.

Solution: 
Install the latest version:

   * If you are using Drupal 8.8.x, upgrade to Drupal 8.8.10 [3].
   * If you are using Drupal 8.9.x, upgrade to Drupal 8.9.6 [4].
   * If you are using Drupal 9.0.x, upgrade to Drupal 9.0.6 [5].

Versions of Drupal 8 prior to 8.8.x are end-of-life and do not receive
security coverage. Sites on 8.7.x or earlier should update to 8.8.10.
