Is this vulnerability remotely exploitable?

Yes. Any remote user who can reach the affected NiceGUI media endpoints and send crafted HTTP requests with query parameters can attempt to exploit the vulnerability.

What level of access does an attacker need?

Typically only network access to the application is required. If the media endpoints are publicly exposed and do not require authentication, even unauthenticated users may trigger excessive memory consumption.

What is the safest general fix pattern?

Enforce strict validation and whitelisting of query parameters used by media routes and decouple streaming behavior from direct client control. Ensure that server-side code always uses safe, bounded, chunked streaming patterns regardless of client input.
