View online: https://www.drupal.org/sa-core-2026-003 Project: Drupal core [1] Date: 2026-April-15 Security risk: *Moderately critical* 13 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2] Vulnerability: Cross-site scripting Affected versions: >= 11.3.0 < 11.3.7 CVE IDs: CVE-2026-6367 Description: Drupal 11.3 comes with support for completing entity suggestions whilst adding a link to CKEditor 5. The suggestions aren't sufficiently sanitized and a malicious user could trigger a stored cross site scripting attack against another user. Solution: Install the latest version: * If you use Drupal 11.3.x, update to Drupal 11.3.7 [3] * Drupal versions below 11.3 are not affected by this vulnerability Reported By: * cantina_security [4] * Dries Buytaert (dries) [5] * Shirsendu Mondal [6] Fixed By: * Lee Rowlands (larowlan) [7] of the Drupal Security Team * Drew Webber (mcdruid) [8] of the Drupal Security Team * Mingsong (mingsong) [9], provisional member of the Drupal Security Team Coordinated By: * Damien McKenna (damienmckenna) [10] of the Drupal Security Team * Greg Knaddison (greggles) [11] of the Drupal Security Team * Lee Rowlands (larowlan) [12] of the Drupal Security Team * Juraj Nemec (poker10) [13] of the Drupal Security Team * Jess (xjm) [14] of the Drupal Security Team Security issue: https://git.drupalcode.org/security/34-drupal-security/-/work_items/1 [15] ------------------------------------------------------------------------------ Contribution record [16] [1] https://www.drupal.org/project/drupal [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/drupal/releases/11.3.7 [4] https://www.drupal.org/u/cantina_security [5] https://www.drupal.org/u/dries [6] https://www.drupal.org/u/shirsendu-mondal [7] https://www.drupal.org/u/larowlan [8] https://www.drupal.org/u/mcdruid [9] https://www.drupal.org/u/mingsong [10] https://www.drupal.org/u/damienmckenna [11] https://www.drupal.org/u/greggles [12] https://www.drupal.org/u/larowlan [13] https://www.drupal.org/u/poker10 [14] https://www.drupal.org/u/xjm [15] https://git.drupalcode.org/security/34-drupal-security/-/work_items/1 [16] https://new.drupal.org/contribution-record?source_link=https%3A//www.drupal…

Drupal core - Moderately critical - Gadget Chain - SA-CORE-2026-002

View online: https://www.drupal.org/sa-core-2026-002 Project: Drupal core [1] Date: 2026-April-15 Security risk: *Moderately critical* 14 ∕ 25 AC:Complex/A:Admin/CI:All/II:All/E:Theoretical/TD:Uncommon [2] Vulnerability: Gadget Chain Affected versions: >= 8.0.0 < 10.5.9 || >= 10.6.0 < 10.6.7 || >= 11.0.0 < 11.2.11 || >= 11.3.0 < 11.3.7 CVE IDs: CVE-2026-6366 Description: Drupal core contains a chain of methods that could be exploitable when an insecure deserialization vulnerability exists on the site. This so-called "gadget chain" presents no direct threat, but is a vector that can be used to achieve remote code execution or SQL injection if the application deserializes untrusted data due to another vulnerability. This issue is not directly exploitable. This issue is mitigated by the fact that in order for it to be exploitable, a separate vulnerability must be present to allow an attacker to pass unsafe input to unserialize(). There are no such known exploits in Drupal core. Solution: Install the latest version: * If you use Drupal 10.5.x, update to Drupal 10.5.9 [3]. * If you use Drupal 10.6.x, update to Drupal 10.6.7 [4]. * If you use Drupal 11.2.x, update to Drupal 11.2.11 [5]. * If you use Drupal 11.3.x, update to Drupal 11.3.7 [6]. 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 [7] and Drupal 9 [8] have both reached end-of-life.)

Orejime - Moderately critical - Cross-site scripting - SA-CONTRIB-2026-032
by security-news＠drupal.org 08 Apr '26

08 Apr '26

View online: https://www.drupal.org/sa-contrib-2026-032 Project: Orejime [1] Date: 2026-April-08 Security risk: *Moderately critical* 13 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2] Vulnerability: Cross-site scripting Affected versions: <2.0.16 Description: The IframeConsent element writes HTML attributes without escaping their value. This module has a XSS vulnerability. If an attacker is able to write an tag, they may be able to insert arbitrary JavaScript. This vulnerability is mitigated by the fact that a text format that allows iframe-consent HTML tags with alt attributes in the necessary option (/Enable JS Iframe consent/) must be enabled, and an attacker must have a role allowing the creation or modification of content in a field with text the format. Solution: Install the latest version: * If you use the 2.x branch of Orejime, upgrade to Orejime 2.0.16 [3]. Reported By: * Pierre Rudloff (prudloff) [4] of the Drupal Security Team Fixed By: * Fabien Gutknecht (fabsgugu) [5] * Pierre Rudloff (prudloff) [6] of the Drupal Security Team Coordinated By: * Juraj Nemec (poker10) [7] of the Drupal Security Team * Pierre Rudloff (prudloff) [8] of the Drupal Security Team * Jess (xjm) [9] of the Drupal Security Team ------------------------------------------------------------------------------ Contribution record [10] [1] https://www.drupal.org/project/orejime [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/orejime/releases/2.0.16 [4] https://www.drupal.org/u/prudloff [5] https://www.drupal.org/u/fabsgugu [6] https://www.drupal.org/u/prudloff [7] https://www.drupal.org/u/poker10 [8] https://www.drupal.org/u/prudloff [9] https://www.drupal.org/u/xjm [10] https://new.drupal.org/contribution-record?source_link=https%3A//www.drupal…

The module doesn't sufficiently block access, leading to a authentication bypass vulnerability. Solution: Install the latest version: If you are using the /SAML SSO - Service Provider/ module for Drupal, upgrade to SAML SSO - Service Provider 3.1.4 [3].
