How broadly exploitable is this vulnerability?

The vulnerability can be exploited over the internet whenever an administrator with an active session visits an attacker-controlled site or embedded content. The attacker does not need direct access to the AVideo instance but relies on the victim's browser to relay forged requests.

What level of access does an attacker need to exploit it?

The attacker does not need valid AVideo credentials. Exploitation requires only that a logged-in administrator's browser load a malicious page capable of issuing cross-origin POST requests. The attacker benefits from any admin session already established in the victim's browser.

What is the safest general fix pattern for this issue?

The most robust fix is to introduce consistent CSRF protection across all admin state-changing endpoints. This typically involves generating CSRF tokens for admin sessions, embedding them in forms or JavaScript calls, and validating them on the server for every POST/PUT/DELETE request before applying changes, combined with reapplying table-level security checks for sensitive configuration tables.
