Project: Drupal coreDate: 2020-May-20Security risk: Moderately critical 10∕25 AC:Basic/A:None/CI:None/II:None/E:Theoretical/TD:AllVulnerability: Open RedirectDescription: 

Drupal 7 has an Open Redirect vulnerability. For example, a user could be tricked into visiting a specially crafted link which would redirect them to an arbitrary external URL.

The vulnerability is caused by insufficient validation of the destination query parameter in the drupal_goto() function.

Other versions of Drupal core are not vulnerable.

Solution: 

Install the latest version:

• If you use Drupal 7.x upgrade to Drupal 7.70

Project: Drupal coreDate: 2020-May-20Security risk: Moderately critical 10∕25 AC:Complex/A:Admin/CI:Some/II:Some/E:Theoretical/TD:UncommonVulnerability: Cross Site ScriptingDescription: 

The jQuery project released version 3.5.0, and as part of that, disclosed two security vulnerabilities that affect all prior versions. As mentioned in the jQuery blog, both are

[...] security issues in jQuery’s DOM manipulation methods, as in .html(), .append(), and the others. Security advisories for both of these issues have been published on GitHub.

Those advisories are:

• CVE-2020-11022
• CVE-2020-11023

These vulnerabilities may be exploitable on some Drupal sites. This Drupal security release backports the fixes to the relevant jQuery functions, without making any other changes to the jQuery version that is included in Drupal core or running on the site via some other module such as jQuery Update. It is not necessary to update jquery_update on Drupal 7 sites that have the module installed.

Backwards-compatibility code has also been added to minimize regressions to Drupal sites that might rely on jQuery's prior behavior. With jQuery 3.5, incorrect self-closing HTML tags in JavaScript for elements where end tags are normally required will encounter a change in what jQuery returns or inserts. To minimize that disruption in 8.8.x and earlier, this security release retains jQuery's prior behavior for most safe tags. There may still be regressions for edge cases, including invalidly self-closed custom elements on Internet Explorer.

(Note: the backwards compatibility layer will not be included in the upcoming Drupal 8.9 and 9.0 releases, so Drupal 8 and 9 modules, themes, and sites should correct tags in JavaScript to properly use closing tags.)

If you find a regression caused by the jQuery changes, please report it in Drupal core's issue queue (or that of the relevant contrib project). However, if you believe you have found a security issue, please report it privately to the Drupal Security Team.

Solution: 

Install the latest version:

• If you are using Drupal 8.8, upgrade to Drupal 8.8.6.
• If you are using Drupal 8.7, upgrade to Drupal 8.7.14.
• If you are using Drupal 7, upgrade to Drupal 7.70.

Versions of Drupal 8 prior to 8.7 are end-of-life and do not receive security coverage. Sites on 8.6 or earlier should update to 8.7.14.

The pre-release Drupal versions (8.9 and 9.0) have been updated jQuery to version 3.5.1 as of 8.9.0-beta3 and 9.0.0-beta3.

Project: Drupal coreVersion: 8.8.x-dev8.7.x-devDate: 2020-March-18Security risk: Moderately critical 13∕25 AC:Complex/A:User/CI:Some/II:Some/E:Proof/TD:DefaultVulnerability: Third-party libraryDescription: 

The Drupal project uses the third-party library CKEditor, which has released a security improvement that is needed to protect some Drupal configurations.

Vulnerabilities are possible if Drupal is configured to use the WYSIWYG CKEditor for your site's users. An attacker that can create or edit content may be able to exploit this Cross Site Scripting (XSS) vulnerability to target users with access to the WYSIWYG CKEditor, and this may include site admins with privileged access.

The latest versions of Drupal update CKEditor to 4.14 to mitigate the vulnerabilities.

Solution: 

Install the latest version:

• If you are using Drupal 8.8.x, upgrade to Drupal 8.8.4.
• If you are using Drupal 8.7.x, upgrade to Drupal 8.7.12.

Versions of Drupal 8 prior to 8.7.x have reached end-of-life and do not receive security coverage.

The CKEditor module can also be disabled to mitigate the vulnerability until the site is updated.

Note for Drupal 7 users

Drupal 7 core is not affected by this release; however, users who have installed the third-party CKEditor library (for example, with a contributed module) should ensure that the downloaded library is updated to CKEditor 4.14 or higher, or that CDN URLs point to a version of CKEditor 4.14 or higher. Disabling all WYSIWYG modules can mitigate the vulnerability until the site is updated.
