Project: Drupal core [1]
Date: 2021-September-15
Security risk: *Moderately critical* 12∕25
AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:Default [2]
Vulnerability: Access Bypass

CVE IDs: CVE-2020-13677
Description: 
Under some circumstances, the Drupal core JSON:API module does not properly
restrict access to certain content, which may result in unintended access
bypass.

Sites that do not have the JSON:API module enabled are not affected.

This advisory is not covered by Drupal Steward [3].

Solution: 
Install the latest version:

   * If you are using Drupal 9.2, update to Drupal 9.2.6 [4].
   * If you are using Drupal 9.1, update to Drupal 9.1.13 [5].
   * If you are using Drupal 8.9, update to Drupal 8.9.19 [6].

Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x
are end-of-life and do not receive security coverage.

Drupal 7 core does not include the JSON:API module and therefore is not
affected.
