CVE-2023-41892Public exploitNetwork attack vector

Unauthenticated code execution via condition configuration

Published Sep 13, 2023 · Updated Feb 13, 2025

Code injection in Pixel & Tonic Craft CMS 4.0.0-RC1 through 4.4.14 allows remote attackers to execute arbitrary server-side code. ConditionsController::beforeAction() creates and configures a condition from request body data before authorization, accepting Yii “as ” and “on ” keys that attach attacker-selected behaviors or event handlers. No authentication or user interaction is required; execution runs with web-service privileges and can expose application secrets, alter data, or interrupt the site.
