Is this vulnerability remotely exploitable?

Yes. An attacker can exploit the vulnerability remotely by sending or sharing a specially crafted URL that targets an affected `list_html` directory listing endpoint. When a victim's browser loads that URL, the attacker-controlled path is reflected and can execute in the victim's session.

Does exploitation require authentication or special privileges?

Not inherently. If the directory listing endpoint is publicly accessible, any remote user can attempt exploitation. If it is protected behind authentication, an attacker would need a way to make an authenticated victim access a crafted URL, or would need their own access to test and refine an exploit.

What is the safest general fix pattern for developers?

The most robust fix is to ensure that all request-derived data used in HTML—especially paths and query parameters—is passed through context-appropriate escaping before rendering. In practice, this means relying on template engines with auto-escaping enabled, avoiding raw HTML output routines, and explicitly encoding `current.path` (and similar values) when displayed.
