SCA: security update for craftcms/cms (GHSA-2fph-6v5w-89hh)

high Tenable Cloud Security Plugin ID 439143

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Craft CMS is a content management system (CMS). From version 5.6.0 to before version 5.9.13, a Remote Code
Execution (RCE) vulnerability exists in Craft CMS, it can be exploited by any authenticated user with
control panel access. This is a bypass of a previous fix. The existing patches add cleanseConfig() to
assembleLayoutFromPost() and various FieldsController actions to strip Yii2 behavior/event injection keys
("as" and "on" prefixed keys). However, the fieldLayouts parameter in
ElementIndexesController::actionFilterHud() is passed directly to FieldLayout::createFromConfig() without
any sanitization, enabling the same behavior injection attack chain. This issue has been patched in
version 5.9.13. (CVE-2026-33157)

Solution

Update the craftcms/cms library and its related packages to version 5.9.13 or later.
