Software Update: Drupal 7.73 / 8.8.10 / 8.9.6 / 9.0.6

Updates have been released for versions 7.7, 8.8, 8.9 and 9.0 of Drupal. Drupal is a PHP-written, user-friendly and powerful content management platform, with which, for example, websites can be created. It’s simple enough for a novice user, but powerful enough to build a more complex website as well. The program includes a content management platform and a development framework. The updates contain fixes for five security vulnerabilities and no other changes.

Which release do I choose? Security coverage information

• Drupal 9.0.x will receive security coverage until June 2, 2021 when Drupal 9.2.0 is released.
• Sites on 8.9.x should update immediately to Drupal 8.9.6 instead.
• Sites on 8.8.x or earlier should update immediately to Drupal 8.8.10 instead, and plan to update to the latest 8.9.x or 9.0.x release before December 2, 2020 (when Drupal 9.1.0 is scheduled for release and 8.8.x security coverage ends).
• Versions of Drupal 8 prior to 8.8.x are end-of-life and do not receive security coverage.

Important update information

• Once a site running Workspaces is upgraded for SA-CORE-2020-008, authenticated users may continue to see unauthorized workspace content that they accessed previously until they are logged out.
  If it is important for the unintended access to stop immediately, you may wish to end all active user sessions on your site (for example, by truncating the sessions table). Be aware that this will immediately log all users out and can cause side effects like lost user input.
• Sites that override DrupalCoreFormFormBuilder’s renderPlaceholderFormAction() and/or buildFormAction() methods in contrib and/or custom code should ensure that appropriate sanitization is applied for URLs for SA-CORE-2020-009.
• Any site that relies on Drupal’s AJAX API to perform trusted JSONP requests will need to either override the AJAX options to set “jsonp: true” or use the jQuery AJAX API directly.
  If you are using jQuery’s AJAX API for user-provided URLs in a contrib or custom module, you should review your code and set “jsonp: false” where this is appropriate.
• No changes have been made to the .htaccess, web.config, robots.txt, or default settings.php files in this release, so upgrading custom versions of those files is not necessary if your site is already on the previous release.
