Summary

Craft CMS from 5.0.0 before 5.11.0 contains a remote code execution flaw (CWE-94) in how Asset::getMimeType transforms handle user-supplied keys. An authenticated Control Panel user can escape the Twig sandbox by supplying 'as' or 'on' keys that are passed unfiltered to Craft::createObject, attaching malicious behaviors or event handlers that run code as the web user. The CVSS 4.0 vector shows low privileges required and no user interaction, with high impact to confidentiality, integrity and availability.
