Craft CMS 5.0.0-RC1 to 5.10.5 and 4.0.0-RC1 to 4.18.1 allow arbitrary file read via SplFileObject in Twig templates. The create() function blocklist omits SplFileObject, so an admin with allowAdminChanges=true can configure a section title or URI format that instantiates SplFileObject, causing files like .env to be read and rendered as entry titles.
