As part of this 1.13.0 update, they disclosed the following security issue that may affect Drupal 9 and 7: * CVE-2021-41183: XSS in the of option of the .position() util [4] It is possible that this vulnerability is exploitable with some Drupal modules. As a precaution, this Drupal security release applies the fix for the above cross-site description issue, without making any of the other changes to the jQuery version that is included in Drupal.
