The QuickEdit module does not properly validate access to routes, which could allow cross-site request forgery under some circumstances and lead to possible data integrity issues.
Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed. Removing the “access in-place editing” permission from untrusted users will not fully mitigate the vulnerability.
This advisory is not covered by Drupal Steward.
Install the latest version:
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 QuickEdit module and therefore is not affected.
Uninstalling the QuickEdit module will also mitigate the vulnerability. Site owners may wish to consider this option as the QuickEdit module will be removed from core in Drupal 10.
