> The vulnerability received the CVE-2018-9206 identifier earlier this month, a good starting point to get more people paying attention.
> All jQuery File Upload versions before 9.22.1 are vulnerable. Since the vulnerability affected the code for handling file uploads for PHP apps, other server-side implementations should be considered safe.
