Is this vulnerability remotely exploitable over the internet?

Yes. An attacker can host a malicious web page and trick an authenticated administrator into visiting it. When the page loads, the victim's browser can issue cross-site requests to the vulnerable AVideo instance, leveraging the admin's session cookies to change permissions.

Does the attacker need to be authenticated to exploit this?

The attacker does not need administrative access but typically benefits from having, or targeting, a specific user group that can be escalated. The critical precondition is that a privileged user is authenticated in the browser and visits attacker-controlled content.

What is the safest general fix pattern for this issue?

Require CSRF tokens on all permission-changing and administrative endpoints, avoid using GET for state-changing operations, and ensure that session cookies for admin functions use conservative `SameSite` settings or are protected by strong CSRF and origin checks.
