Is this vulnerability remotely exploitable?

Yes. If the SickBeard Alpha web interface is reachable from an attacker's network and configuration endpoints are exposed, an attacker can exploit the extra scripts field remotely.

Does an attacker need valid credentials to exploit this?

The description indicates the issue is exploitable by unauthenticated attackers, meaning no valid user account is required when the vulnerable endpoints are not protected by authentication.

What is the safest general fix pattern for developers?

Remove or redesign the feature so that user-configurable values cannot be executed as raw commands. Instead, expose a limited set of predefined actions and invoke them using safe process APIs without a shell, enforcing strict validation and whitelisting.
