Is this vulnerability remotely exploitable?

Yes. As long as the OpenCTI HTTP(S) interface is reachable, an attacker can exploit this issue remotely by sending crafted GET requests to the `/static/css` endpoint, without any authentication.

Does an attacker need valid credentials or local access?

No. The vulnerability is exploitable by unauthenticated users. The only requirement is network access to the vulnerable OpenCTI instance.

What is the safest general fix pattern?

The safest pattern is to ensure that any file-serving logic: - Canonicalizes and normalizes the incoming path - Enforces that resolved paths cannot escape a predefined static root - Uses framework or library mechanisms for static file serving that provide built-in protection against path traversal.
