Impact
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.
Patches
This is fixed in Bolt 3.7.1.
