Overview
craftcms/cms is a content management system.
Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs via the create function in non-sandboxed template contexts. An attacker can access arbitrary files on the server filesystem by instantiating SplFileObject with a chosen file path. This is only exploitable if an attacker has admin access to the control panel, allowAdminChanges is set to true, and the attacker can edit entry type settings such as title or URI format.
