CVE-2020-4041 Information

Description

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.
