CVE-2026-29113 Details
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 That token can then be used by the attacker (without authentication) to access previewed/unpublished content tied to the victim’s authorized preview scope.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.
A cross-site request forgery (CSRF) vulnerability has been identified in Craft CMS versions 4.0.0-RC1 prior to 4.17.3 and 5.0.0-RC1 prior to 5.9.6. The issue resides in the preview token endpoint, which accepts an attacker-supplied preview token. The endpoint does not require POST requests or enforce CSRF token validation, allowing an attacker to manipulate a logged-in victim editor into generating a preview token of their choice. This token can then be used, without authentication, to access previewed or unpublished content within the victim's authorized preview scope.
Users can update to Craft CMS versions 4.17.4 or 5.9.7 to address this vulnerability.
