Is this vulnerability remotely exploitable?

Yes, it can be exploited remotely, but only by users who have valid credentials and access to the file upload functionality. Once authenticated, an attacker can craft upload requests over the network.

Does an attacker need special privileges or roles?

The attacker generally needs any CMS account that permits file or media uploads. Elevated administrative privileges are not strictly required if lower-privileged roles can upload files to a web-accessible location.

What is the safest general fix pattern?

The safest pattern is to combine strict server-side file validation with segregated storage: only allow known-safe types via whitelisting, verify MIME and content, and ensure uploaded files are stored in non-executable directories that the web server does not use for code.
