Is this vulnerability remotely exploitable?

Yes, the flaw affects the network-exposed WebSocket API, so a remote attacker who can connect to this interface may be able to exploit it, depending on network topology and access controls.

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

An attacker needs the ability to initiate a WebSocket connection to the media server and send crafted messages. This typically requires network reachability to the interface hosting the API, but not necessarily valid application-level credentials if the API is insufficiently protected.

What is the safest general fix pattern for this vulnerability?

The safest pattern is to remove any dynamic code or command generation based on WebSocket input, replace it with strictly defined command schemas, and ensure that all processing of client-supplied data treats it purely as data, not as executable logic. Any necessary scripting should operate on pre-validated, strongly typed parameters rather than raw text.
