Official Description

Craft CMS (composer package craftcms/cms) versions >= 5.5.0 and <= 5.9.13 contain a remote code execution vulnerability in the FieldsController::actionRenderCardPreview() method, which passes the fieldLayoutConfig POST parameter directly to Fields::createLayout() without calling Component::cleanseConfig(). An authenticated admin user can inject Yii2 event handlers (e.g., 'on init' keys) via the fieldLayoutConfig parameter to execute arbitrary PHP code and disclose sensitive information (such as environment variables containing database credentials and CRAFT_SECURITY_KEY). The issue is fixed in version 5.9.14.

Technical Analysis

CVE-2026-56382 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.2.
