Date: 
2021-September-15
Security risk: 
Moderately critical 10∕25 AC:Basic/A:User/CI:None/II:Some/E:Theoretical/TD:Default
Vulnerability: 
Cross Site Request Forgery
CVE IDs: 
CVE-2020-13673
Description: 

The Drupal core Media module allows embedding internal and external media in content fields. In certain circumstances, the filter could allow an unprivileged user to inject HTML into a page when it is accessed by a trusted user with permission to embed media. In some cases, this could lead to cross-site scripting.

This advisory is not covered by Drupal Steward.

Also see Entity Embed – Moderately critical – Cross Site Request Forgery – SA-CONTRIB-2021-028 which addresses a similar vulnerability for that module.

Updated 18:15 UTC to clarify text.

Solution:

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.
