Is this vulnerability remotely exploitable over the internet?

Yes, if the AVideo admin interface is reachable and an administrator browses attacker-controlled content, an attacker can trigger a cross-site request from anywhere on the internet. The attacker does not need direct access to the AVideo server, only the ability to get an admin to load a malicious page.

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

The attacker does not need valid credentials on the AVideo instance. They rely on the presence of a logged-in admin in their own browser and the lack of CSRF protection on the plugin import endpoint, combined with cookies being sent cross-site.

What is the safest general fix pattern for developers?

Protect all authenticated, state-changing endpoints with CSRF defenses, including server-side token validation and strict origin or referer checks, and avoid using `SameSite=None` unless there is a clear, justified requirement. For plugin upload endpoints, also treat uploaded content as untrusted code and apply additional safeguards such as validation, review workflows, and constrained execution.
