Drupal core - Highly critical - SQL injection - SA-CORE-2026-004
by security-news＠drupal.org 20 May '26

20 May '26

View online: https://www.drupal.org/sa-core-2026-004 Project: Drupal core [1] Date: 2026-May-20 Security risk: *Highly critical* 20 ∕ 25 AC:None/A:None/CI:All/II:All/E:Theoretical/TD:Uncommon [2] Vulnerability: SQL injection Affected 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 < 11.3.10 CVE IDs: CVE-2026-9082 Description: 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 vulnerability *only affects sites using PostgreSQL*. However, the dependency updates in this release apply to all sites. .... 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 [3] 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. *The following releases will be available as soon as automated release packaging is complete.* You may receive a 404 in the interim. The updates may also be available on Packagist sooner. .. Drupal 11 * If you use Drupal 11.3.x, update to Drupal 11.3.10 [4]. * If you use Drupal 11.2.x, update to Drupal 11.2.12 [5]. * If you use Drupal 11.1.x or 11.0.x, update to Drupal 11.1.10 [6]. .. Drupal 10 * If you use Drupal 10.6.x, update to Drupal 10.6.9 [7]. * If you use Drupal 10.5.x, update to Drupal 10.5.10 [8]. * If you use Drupal 10.4.x or earlier, update to Drupal 10.4.10 [9]. .. Drupal 9 and 8 * If you use any version of Drupal 9, try manually applying the Drupal 9.5 patch for this issue [10]. * If you use Drupal 8.9, try manually applying the Drupal 8.9 patch for this issue [11]. 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 [12] and Drupal 9 [13] 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.

Upcoming highly critical release on May 20, 2026 - PSA-2026-05-18
by security-news＠drupal.org 18 May '26

18 May '26

View online: https://www.drupal.org/psa-2026-05-18 Date: 2026-May-18 Description: 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 [1].) The Drupal Security Team urges you to reserve time for core updates at that time because exploits /might/ be developed within hours or days. The risk is currently rated as: Highly critical 20 ∕ 25 AC:None/A:None/CI:All/II:All/E:Theoretical/TD:Uncommon. 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 [2], 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 in preparation for the window. * Sites on Drupal 10.4, 10.3, 10.2, 10.1, or 10.0 should update to at least Drupal 10.4.9 in preparation for the window. 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 [3] and SA-CORE-2026-002 [4], 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 in preparation for the window. * Sites on any version of Drupal 8 should update to Drupal 8.9.20 in preparation for the window. 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. .... Disclosure policy Neither the Security Team nor any other party is able to release any more information about this vulnerability until the announcement is made. The announcement will be made public at https://www.drupal.org/security [5], on Bluesky [6], Mastodon [7], X (formerly Twitter) [8], and LinkedIn [9], and in email for those who have subscribed to our email list. To subscribe to the email list: log in on Drupal.org, go to your user profile page and subscribe to the security newsletter on the Edit » My newsletters tab. Security release announcements will appear on the Drupal.org security advisory page [10] which also has RSS feeds.

The module doesn't sufficiently sanitize the data-colorbox-inline attribute value before passing it to jQuery, leading to a Cross-Site Scripting (XSS) vulnerability. This vulnerability is mitigated by the fact that an attacker must have a role with permission to enter HTML tags containing specific data attributes.

Translate Drupal with GTranslate - Less critical - DOM clobbering / link manipulation - SA-CONTRIB-2026-035

View online: https://www.drupal.org/sa-contrib-2026-035 Project: Translate Drupal with GTranslate [1] Date: 2026-May-13 Security risk: *Less critical* 8 ∕ 25 AC:Basic/A:Admin/CI:None/II:Some/E:Theoretical/TD:Uncommon [2] Vulnerability: DOM clobbering / link manipulation Affected versions: <3.0.5 CVE IDs: CVE-2026-8492 Description: The GTranslate module provides a language switcher widget for Drupal sites. The module’s widget JavaScript did not sufficiently validate that document.currentScript referred to the executing script element. A user who can add HTML to a page could cause the generated language-switcher links to point to an unintended domain. This vulnerability is mitigated by the fact that an attacker must be able to add HTML with attributes that are not allowed by Drupal’s default CKEditor configuration. It is also limited to sites using the paid versions of GTranslate widget JavaScript and configurations where the generated language links use script-provided values. Solution: Install the latest version. If you use the GTranslate module 3.0.x, upgrade to GTranslate 3.0.5 [3].
