Craft CMS versions 4.0.0-RC1 through before 4.18.2 and 5.0.0-RC1 through before 5.10.6 contain an arbitrary file read vulnerability. This occurs because the create() Twig function's class instantiation blocklist does not include SplFileObject, allowing an authenticated administrator with allowAdminChanges=true to instantiate SplFileObject in a non-sandboxed template context. This can lead to arbitrary files on the server, such as .env files containing sensitive credentials, being read and rendered in entry titles.

Craft CMS 5.0.0-RC1 before 5.10.6 and 4.0.0-RC1 before 4.18.2 contain an arbitrary file read vulnerability. The create() Twig function restricts class instantiation using a 5-entry blocklist that does not include SplFileObject, allowing an authenticated administrator (with allowAdminChanges=true) to configure a malicious entry type title or URI format that instantiates SplFileObject in a non-sandboxed template context. When a user subsequently creates an entry in the affected section, arbitrary files on the server (such as .env containing the security key and database credentials) are read and rendered as entry titles.
