Controller/Backend/FileEditController.php and Controller/Backend/FilemanagerController.php in Bolt before 4.1.13 allow Directory Traversal.

Bolt before 3.7.2 does not restrict filter options in a Request in the Twig context, and is therefore inconsistent with the "How to Harden Your PHP for Better Security" guidance.

In Bolt CMS before version 3.7.1, the filename of uploaded files was vulnerable to stored XSS. It is not possible to inject javascript code in the file name when creating/uploading the file. But, once created/uploaded, it can be renamed to inject the payload in it. Additionally, the measures to prevent renaming the file to disallowed filename extensions could be circumvented. This is fixed in Bolt 3.7.1.

Bolt CMS before version 3.7.1 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. This has been fixed in Bolt 3.7.1
