{"id":"GHSA-2q66-6cc3-6xm8","summary":"CSRF issue on preview pages in Bolt CMS","details":"### Impact\n\nBolt CMS lacked CSRF protection in the preview generating endpoint. Previews are intended to be generated by the admins, developers, chief-editors, and editors, who are authorized to create content in the application. But due to lack of proper CSRF protection, unauthorized users could generate a preview.\n\n### Patches\n\nThis has been fixed in Bolt 3.7.1\n\n### References\n\nRelated issue: https://github.com/bolt/bolt/pull/7853","aliases":["CVE-2020-4040"],"modified":"2026-05-07T05:02:54.840283542Z","published":"2020-06-09T00:25:41Z","database_specific":{"cwe_ids":["CWE-352"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2020-06-08T21:52:37Z","nvd_published_at":"2020-06-08T22:15:00Z"},"references":[{"type":"WEB","url":"https://github.com/bolt/bolt/security/advisories/GHSA-2q66-6cc3-6xm8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-4040"},{"type":"WEB","url":"https://github.com/bolt/bolt/pull/7853"},{"type":"WEB","url":"https://github.com/bolt/bolt/commit/b42cbfcf3e3108c46a80581216ba03ef449e419f"},{"type":"PACKAGE","url":"https://github.com/bolt/bolt"},{"type":"WEB","url":"http://packetstormsecurity.com/files/158299/Bolt-CMS-3.7.0-XSS-CSRF-Shell-Upload.html"},{"type":"WEB","url":"http://seclists.org/fulldisclosure/2020/Jul/4"}],"affected":[{"package":{"name":"bolt/bolt","ecosystem":"Packagist","purl":"pkg:composer/bolt/bolt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7.1"}]}],"versions":["3.5.7","v0.8.4","v0.8.5","v0.9.10","v0.9.5","v1.0.0","v1.0.5","v1.1.2","v1.1.4","v1.2.1","v1.3.0","v1.4.0","v1.4.3","v1.5.1","v1.5.6","v1.6.0","v1.6.2","v1.6.3","v1.6.3.1","v1.6.9","v2.0.0","v2.0.1","v2.0.2","v2.0.3","v2.0.4","v2.0.5","v2.0.6","v2.1.0","v2.1.1","v2.1.1-pl1","v2.1.2","v2.1.3","v2.1.3-pl1","v2.1.4","v2.1.4-pl1","v2.1.5","v2.1.6","v2.1.7","v2.1.8","v2.1.8-pl1","v2.1.9","v2.2.0","v2.2.1","v2.2.10","v2.2.11","v2.2.13","v2.2.14","v2.2.15","v2.2.16","v2.2.17","v2.2.18","v2.2.19","v2.2.19-pl1","v2.2.2","v2.2.20","v2.2.21","v2.2.22","v2.2.23","v2.2.24","v2.2.25","v2.2.3","v2.2.4","v2.2.5","v2.2.6","v2.2.7","v2.2.8","v2.2.9","v3.0.0","v3.0.1","v3.0.10","v3.0.11","v3.0.12","v3.0.2","v3.0.3","v3.0.4","v3.0.5","v3.0.6","v3.0.7","v3.0.8","v3.0.9","v3.1.0","v3.1.1","v3.1.2","v3.1.3","v3.1.4","v3.1.5","v3.1.6","v3.2.0","v3.2.1","v3.2.10","v3.2.11","v3.2.12","v3.2.13","v3.2.14","v3.2.15","v3.2.16","v3.2.17","v3.2.18","v3.2.19","v3.2.2","v3.2.20","v3.2.3","v3.2.4","v3.2.5","v3.2.6","v3.2.7","v3.2.8","v3.2.9","v3.3.0","v3.3.1","v3.3.2","v3.3.3","v3.3.4","v3.3.5","v3.3.6","v3.4.0","v3.4.1","v3.4.10","v3.4.11","v3.4.2","v3.4.3","v3.4.4","v3.4.5","v3.4.6","v3.4.7","v3.4.8","v3.4.9","v3.5.0","v3.5.1","v3.5.2","v3.5.3","v3.5.4","v3.5.5","v3.5.6","v3.6.0","v3.6.0-beta.1","v3.6.0-beta.2","v3.6.0-beta.3","v3.6.0-beta.4","v3.6.0-beta.5","v3.6.0-beta.6","v3.6.0-beta.7","v3.6.1","v3.6.10","v3.6.11","v3.6.2","v3.6.3","v3.6.4","v3.6.5","v3.6.6","v3.6.7","v3.6.8","v3.6.9","v3.7.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/06/GHSA-2q66-6cc3-6xm8/GHSA-2q66-6cc3-6xm8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N"}]}
