Craft CMS 4.0.0 before 4.18.8 and 5.0.0 before 5.11.0 contains a Twig sandbox allowlist bypass because the column, contains, filterByValue, index, where, and multisort filters resolve caller-supplied keys via ArrayHelper::getValue() without consulting the sandbox security policy. Authenticated Control Panel users can supply dot-path keys to traverse the craft global and disclose the securityKey, database credentials, and auth tokens.
