Description
Craft is a content management system (CMS). Prior to 4.17.3 and 5.9.7, Craft CMS has a CSRF issue in the preview token endpoint at /actions/preview/create-token. The endpoint accepts an attacker-supplied previewToken. Because the action does not require POST and does not enforce a CSRF token, an attacker can force a logged-in victim editor to mint a preview token chosen by the attacker. That token can then be used by the attacker (without authentication) to access previewed/unpublished content tied to the victim’s authorized preview scope. This vulnerability is fixed in 4.17.3 and 5.9.7.
