Date: 2020-June-17
Security risk: *Critical* 15∕25
AC:Complex/A:None/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross Site Request Forgery

CVE IDs: CVE-2020-13663
Description:
The Drupal core Form API does not properly handle certain form input from
cross-site requests, which can lead to other vulnerabilities.

Solution:
* If you are using Drupal 7.x, upgrade to Drupal 7.72 [3].
* If you are using Drupal 8.8.x, upgrade to Drupal 8.8.8 [4].
* If you are using Drupal 8.9.x, upgrade to Drupal 8.9.1 [5].
* If you are using Drupal 9.0.x, upgrade to Drupal 9.0.1 [6].

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 8.8.8.
