Is this SQL injection vulnerability remotely exploitable?

Yes. In typical deployments, it is remotely reachable through the RTMP publish authentication flow or any interface that accepts stream keys and causes `LiveTransmition::keyExists()` to run and fall back to `Live_schedule::keyExists()`.

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

An attacker needs the ability to supply a stream key value—often possible to any authenticated or, in some setups, unauthenticated client attempting to publish a live stream. No direct database access is required; the injection occurs via the application's own database interface.

What is the safest general fix pattern for developers?

Replace all string-concatenated SQL in `Live_schedule::keyExists()` (and similar helpers) with parameterized queries, ensuring that every code path, including fallbacks, uses prepared statements and never interpolates the stream key directly into SQL.
