{"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 4.17.3 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 That token can then be used by the attacker (without authentication) to access previewed/unpublished content tied to the victim’s authorized preview scope.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.","aliases":["GHSA-vg3j-hpm9-8v5v"],"modified":"2026-09-04T03:30:24.877813357Z","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","cna_assigner":"GitHub_M","cwe_ids":["CWE-352"]},"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":"982efcd14d7e93a1a54f0905b61f242de6b53d8a"},{"fixed":"5020fa5be830af712694f9f8164599a1789cc094"},{"introduced":"f6a8fb685d44e387435825e3a96809eeda4973a6"},{"fixed":"9986382fbf26ed5cd46926ecd84084bf1b564680"},{"fixed":"6a88468dc35a27cccc8fef254f415a447d4a07cc"}],"database_specific":{"cpe":"cpe:2.3:a:craftcms:craft_cms:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"4.0.0"},{"fixed":"4.17.4"},{"introduced":"5.0.0"},{"fixed":"5.9.7"}],"source":["CPE_RANGE","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-29113.json"}}],"schema_version":"1.9.0","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"}]}
