CSRF issue on preview pages in Bolt CMS

  • Disclosed: 09.06.2020
  • Updated: 11.10.2026 10:22

Impact

Bolt 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.

Patches

This has been fixed in Bolt 3.7.1
