{"id":"CVE-2026-29113","summary":"Craft has a potential information disclosure vulnerability in preview tokens","details":"Craft is a content management system (CMS). Prior to 4.17.4 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 That token can then be used by the attacker (without authentication) to access previewed/unpublished content tied to the victim’s authorized preview scope.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 4.17.4 and 5.9.7.","aliases":["GHSA-vg3j-hpm9-8v5v"],"modified":"2026-04-10T05:41:33.231188Z","published":"2026-03-10T19:44:44.530Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/29xxx/CVE-2026-29113.json","cwe_ids":["CWE-352"],"cna_assigner":"GitHub_M"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/craftcms/cms","events":[{"introduced":"daac7c1da2f701f2e9ddee1da1457ce61660b581"},{"fixed":"17bf79c1dbc249b6c79d585eba1414838dc43521"}],"database_specific":{"versions":[{"introduced":"4.0.0-RC1"},{"fixed":"4.17.3"}]}},{"type":"GIT","repo":"https://github.com/craftcms/cms","events":[{"introduced":"04755d93f86d07cc183db47db8a0eee106892e30"},{"fixed":"558372701d7870da4a3cda88592a21d962de0cb1"}],"database_specific":{"versions":[{"introduced":"5.0.0-RC1"},{"fixed":"5.9.6"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-29113.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
