CVE-2026-112777 · Craft CMS before 4.18.8 and 5.11.0 Twig create() Blocklist Bypass Leading to RCE
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Craft CMS 4.x before 4.18.8 and 5.x before 5.11.0 contains a blocklist bypass in the Twig create() function because its class-name checks are case-sensitive while PHP class resolution is not. Attackers with template-execution rights, such as Control Panel administrators, can instantiate SplFileObject via a lowercase class name to read .env secrets or write a PHP file into the webroot for remote code execution.
