Project: Drupal coreDate: 2021-May-26Security risk: Moderately critical 14∕25 AC:Basic/A:User/CI:Some/II:Some/E:Proof/TD:DefaultVulnerability: Cross Site ScriptingCVE IDs: CVE-2021-33829Description: 

Update: 2021-06-11: Added CVE-2021-33829 identifier

Drupal core uses the third-party CKEditor library. This library has an error in parsing HTML that could lead to an XSS attack. CKEditor 4.16.1 and later include the fix.

Update: 2021-06-11: More details are available on CKEditor's blog.

Users of the CKEditor library via means other than Drupal core should update their 3rd party code (e.g. the WYSIWYG module for Drupal 7). The Drupal Security Team policy is not to alert for issues affecting 3rd party libraries unless those are shipped with Drupal core. See DRUPAL-SA-PSA-2016-004 for more details.

This issue is mitigated by the fact that it only affects sites with CKEditor enabled.

Solution: 

Install the latest version:

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