Is this vulnerability remotely exploitable?

Yes. Because the vulnerable registration endpoint is typically exposed over the web, attackers can exploit it remotely by submitting crafted signup requests containing malicious uploads.

What level of access does an attacker need to exploit this?

Usually, only the ability to reach the signup page and submit a registration form is required. If registration is open to the public, no prior authentication or special privileges are needed.

What is the safest general fix pattern for this issue?

The safest pattern is to strictly control what can be uploaded (using allowlists and content validation), store files in non-executable locations, and configure the server so that uploaded content can never be executed as code, regardless of file type or extension.
