Is this vulnerability remotely exploitable over the internet?

Yes. Because the vulnerable `base64Url` parameter is supplied via a GET request and does not require authentication, any remote attacker who can reach the affected endpoint can attempt exploitation.

Does an attacker need valid credentials or an account on the platform?

No. The issue is explicitly unauthenticated: the attacker only needs network access to the vulnerable AVideo instance and the ability to send crafted HTTP requests.

What is the safest general fix pattern for this type of issue?

The safest approach is to remove any dependency on shell command construction with user input. Use language-native APIs for file handling and processing, ensure commands never pass through a shell when user-controlled data is involved, and strictly validate that incoming values match narrow, expected formats.
