CVE-2026-32264Network attack vector

Authenticated RCE via uncleansed behavior configuration

Published Mar 16, 2026 · Updated Mar 16, 2026

Behavior injection in Craft CMS 4.0.0-RC1 through 4.17.4 and 5.0.0-RC1 through 5.9.10 allows remote authenticated users to execute code. ElementIndexesController::actionFilterHud passes parsed condition configuration to createCondition without cleansing it, while FieldsController::actionRenderSettings configures a field from uncleansed settings; Yii behavior syntax then attaches a malicious gadget. Control-panel administrator access and allowAdminChanges enabled are required, after which the gadget chain executes arbitrary server commands.
