{"id":"CVE-2026-29113","aliases":["GHSA-vg3j-hpm9-8v5v"],"url":"https://o3.security/vulnerability/CVE-2026-29113","summary":"Craft has a potential information disclosure vulnerability in preview tokens","details":"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 That token can then be used by the attacker (without authentication) to access previewed/unpublished content tied to the victim’s authorized preview scope.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.","published":"2026-03-10T19:44:44.530Z","modified":"2026-09-04T03:30:24.877813357Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"craftcms/cms","fixedVersion":"4.17.3"},{"ecosystem":"Packagist","name":"craftcms/cms","fixedVersion":"5.9.7"}],"fix":{"url":"https://github.com/craftcms/cms/commit/6a88468dc35a27cccc8fef254f415a447d4a07cc","label":"craftcms/cms@6a88468"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29113.json"},{"type":"ADVISORY","url":"https://github.com/craftcms/cms/security/advisories/GHSA-vg3j-hpm9-8v5v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-29113"},{"type":"FIX","url":"https://github.com/craftcms/cms/commit/6a88468dc35a27cccc8fef254f415a447d4a07cc"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-04T03:30:24.877813357Z"}}
