Set an option in Pressero that allows me to indicate which file types are allowed when uploading files to products.
I opened a ticket on this back on June 16, 2020. It caused a huge headache for us when someone uploaded a phishing HTML document. It wasn't even accessible to anybody, and we still got flagged by Google as a "bad user". We had emails fail to come in or out, and when someone visited a website that ended in our domain name it presented a warning page indicating that we hosted malware/phishing sites. It took 4 days to clear it all up with Google before we were fully operational again.
I was told then that this was an active feature request. The last reply on my ticket was June 7, 2021 that it was still active but no update on when it would be implemented.
