Project: Anti-Spam by CleanTalkDate: 2026-June-03Security risk: Moderately critical 10 ∕ 25 AC:Complex/A:Admin/CI:Some/II:Some/E:Theoretical/TD:UncommonVulnerability: Cross site scriptingAffected versions: <9.7.1CVE IDs: CVE-2026-10770Description: 

This module provides spam protection using the CleanTalk cloud service.

The module doesn't sufficiently sanitize API response messages before rendering them in HTML output. The _cleantalk_die() and ct_die() functions output the CleanTalk API response message directly into HTML without proper sanitization, allowing potential injection of arbitrary HTML or JavaScript.

This vulnerability is mitigated by the fact that an attacker must be able to influence the CleanTalk cloud API response (e.g., through a man-in-the-middle attack or a compromised API server).

Solution: 

Install the latest version:

• If you use the Anti-Spam by CleanTalk module for Drupal upgrade to Anti-Spam by CleanTalk 9.7.1

Project: Commerce CoreDate: 2026-June-03Security risk: Moderately critical 14 ∕ 25 AC:Basic/A:None/CI:Some/II:Some/E:Theoretical/TD:UncommonVulnerability: Cross site scriptingAffected versions: >= 3.3.0 < 3.3.6CVE IDs: CVE-2026-10769Description: 

The module doesn't sufficiently sanitize customer comments in the order receipt email template; this could be exploited to achieve Cross-site Scripting (XSS).

This vulnerability is mitigated by the fact that it only affects installations with Checkout (commerce_checkout) enabled, and the "Comments" checkout pane (id: customer_comments) is explicitly used, which is disabled by default.

Solution: 

Install the latest version:

• If you use Commerce Core 3.3.x, upgrade to Commerce Core 3.3.6

Project: TacJSDate: 2026-June-03Security risk: Moderately critical 11 ∕ 25 AC:Basic/A:User/CI:None/II:Some/E:Theoretical/TD:AllVulnerability: Improper Access ControlAffected versions: <6.8CVE IDs:  CVE-2026-49977 Description: 

This module enables sites to comply with the European cookie law using tarteaucitron.js.

The module doesn't sufficiently filter user-supplied markup inside of content leading to an attacker being able to delete arbitrary cookies.

This vulnerability is mitigated by the fact that an attacker needs to be able to insert specific data attributes in the page.

For additional information, see the Github Security Advisory GHSA-jxj7-g6gm-49j7 for the tarteaucitron.js library.

Project: LocalGov WorkflowsDate: 2026-June-03Security risk: Moderately critical 14 ∕ 25 AC:None/A:None/CI:Some/II:None/E:Theoretical/TD:DefaultVulnerability: Information disclosureAffected versions: <1.6.0CVE IDs: CVE-2026-10768Description: 

This module configures default editorial workflows for LocalGov Drupal content types. It provides a Drupal content moderation workflow, a content approvals dashboard, content scheduling and content preview.

The module doesn't sufficiently restrict access to a view of Service Contacts at which exposes the names and content items assigned to each Service Contact.

Project: Drupal AlternativeCommerce (Basket)Date: 2026-May-27Security risk: Highly critical 22 ∕ 25 AC:None/A:None/CI:All/II:All/E:Theoretical/TD:AllVulnerability: Arbitrary PHP code executionAffected versions: <2.1.17CVE IDs: CVE-2026-9726Description: 

The Basket module enables e-commerce and checkout functionality for Drupal sites.

The module does not sufficiently sanitize user-supplied data before passing it to PHP's unserialize().

An attacker can supply a crafted payload and trigger PHP Object Injection. If a viable gadget chain exists in the site codebase or installed dependencies, this can result in arbitrary PHP code execution.

Solution: 

Install the latest version:

• If you use the Basket module, upgrade to Basket 2.1.17.

Project: Drupal coreDate: 2026-May-20Security risk: Highly critical 23 ∕ 25 AC:None/A:None/CI:All/II:All/E:Exploit/TD:UncommonVulnerability: SQL injectionAffected versions: >= 8.9.0 < 10.4.10 || >= 10.5.0 < 10.5.10 || >= 10.6.0 < 10.6.9 || >= 11.0.0 < 11.1.10 || >= 11.2.0 < 11.2.12 || >= 11.3.0 < 11.3.10CVE IDs: CVE-2026-9082Description: 

Drupal core includes a database abstraction API to ensure that queries executed against the database are sanitized to prevent SQL injection attacks.

A vulnerability in this API allows an attacker to send specially crafted requests, resulting in arbitrary SQL injection for sites using PostgreSQL databases. This can lead to information disclosure, and in some cases privilege escalation, remote code execution, or other attacks.

This vulnerability can be exploited by anonymous users.

This SQL injection vulnerability only affects sites using PostgreSQL. However, the third-party dependency updates in these releases apply to all sites.

Updates

May 22 2026, 04:30 UTC: The risk score has been updated to reflect that exploit attempts are now being detected in the wild.

Upstream security advisories

The Drupal releases for supported branches (11.3, 11.2, 10.6, and 10.5) in this advisory also include security updates for Symfony and Twig. Those projects have released important Security Advisories that were coordinated with this Drupal release, and Drupal is affected by some of the vulnerabilities.

Depending on your site configuration and contrib modules, you may be vulnerable to one or more of these upstream issues, so updating these dependencies is highly recommended whether the SQL Injection vulnerability affects you or not. It is also recommended to review which user roles have the ability to update Twig templates, for example via Views or contributed modules.

Solution: 

Install the latest version.

Drupal 11

• If you use Drupal 11.3.x, update to Drupal 11.3.10.
• If you use Drupal 11.2.x, update to Drupal 11.2.12.
• If you use Drupal 11.1.x or 11.0.x, update to Drupal 11.1.10.

Drupal 10

• If you use Drupal 10.6.x, update to Drupal 10.6.9.
• If you use Drupal 10.5.x, update to Drupal 10.5.10.
• If you use Drupal 10.4.x or earlier, update to Drupal 10.4.10.

Drupal 9 and 8

• If you use any version of Drupal 9, try manually applying the Drupal 9.5 patch for this issue.
• If you use Drupal 8.9, try manually applying the Drupal 8.9 patch for this issue.

Drupal 11.1.x, Drupal 11.0.x, Drupal 10.4.x, and below are end-of-life and do not receive security coverage. (Drupal 8 and Drupal 9 have both reached end-of-life.) Due to this issue's severity, the unsupported releases and patches for unsupported versions are provided as a best effort. Those unsupported versions will still have other, previously disclosed security vulnerabilities.

Date: 2026-May-18Security risk: Highly critical 20 ∕ 25 AC:None/A:None/CI:All/II:All/E:Theoretical/TD:UncommonDescription: 

There will be a Drupal core security release for all supported branches on May 20, 2026, between 17:00 and 21:00 UTC. (To see this in your local timezone, refer to the Drupal Core Calendar.) The Drupal Security Team urges you to reserve time for core updates at that time because exploits might be developed within hours or days.

Not all configurations are affected. Reserve time on May 20 during the release window to determine whether your sites are affected and in need of an immediate update. Mitigation information will be included in the advisory.

We recommend updating to the latest supported patch (bugfix) release for your site's version of Drupal before May 20, so that you can address any other upgrade issues before the security window. (Recommendations for specific Drupal versions follow.)

This issue is being protected by Drupal Steward. Sites that use Drupal Steward are already protected from known attack vectors, but should upgrade in the near future in case additional attack vectors are discovered.

Affected versions Supported core versions

Security releases will be provided for all the currently supported branches of Drupal core, which are:

• 11.3.x
• 11.2.x
• 10.6.x
• 10.5.x

Sites on one of these supported versions should update to the latest patch release for the given branch now in preparation for the security window.

End-of-life minor core versions (Drupal 10 and 11)

While the Drupal Security Team does not normally provide security releases for unsupported releases, given the severity of the issue, we are providing 11.1.x and 10.4.x releases that include the fix for sites which have not yet had a chance to update. Therefore, in advance of the window:

• Sites on Drupal 11.1 or 11.0 should update to at least Drupal 11.1.9.
• Sites on Drupal 10.4, 10.3, 10.2, 10.1, or 10.0 should update to at least Drupal 10.4.9.

These sites should apply the security update as soon as it is released on May 20, then plan to update to Drupal 11.3 or 10.6 in the near future. (Two other recent security advisories, SA-CORE-2026-001 and SA-CORE-2026-002, will not be addressed for 11.1 or 10.4.)

End-of-life major core versions (Drupal 8 and 9)

These major versions are fully end-of-life, so no releases will be created for these branches. However, given the potential severity of this issue, we will provide patch files for Drupal 8.9 and 9.5.

These patches must be applied manually. They are not guaranteed to work correctly, and might introduce other bugs or regressions. However, they may help mitigate the vulnerability for sites still on these old major versions until they upgrade to a supported release.

For the best chance of the patches being applied successfully:

• Sites on any version of Drupal 9 should update to Drupal 9.5.11.
• Sites on any version of Drupal 8 should update to Drupal 8.9.20.

We strongly recommend Drupal 8 or 9 sites update to at least Drupal 10.6 soon. Drupal 8 and 9 include numerous other, previously disclosed, security vulnerabilities that will not be addressed by either Drupal Steward or the best-effort patch files.

Drupal 7 is not affected.
