CVE-2026-33157Network attack vector

Authenticated code execution via uncleansed field layout configuration

Published Mar 24, 2026 · Updated Mar 24, 2026

Remote code execution in Pixel & Tonic Craft CMS 5.6.0 through 5.9.12 allows remote authenticated users to run commands via control-panel requests. ElementIndexesController::actionFilterHud() passes the request-controlled fieldLayouts array directly to FieldLayout::createFromConfig() without Component::cleanseConfig(), allowing Yii behavior and event keys to reach dynamic object configuration. A user account with the accessCp permission is required; crafted behavior and wildcard event configuration reaches shell_exec() and runs commands with the web process's privileges.
