The filename of uploaded files vulnerable to stored XSS
### 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. ### References Related issue: https://github.com/bolt/bolt/pull/7853
