Is this vulnerability remotely exploitable over the internet?

Yes, if the Outline instance is reachable over the internet. However, exploitation still requires an authenticated account within the affected team; anonymous users cannot exploit the issue directly.

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

The attacker needs to be a legitimate team member with valid login credentials. Administrator privileges are not required; any authenticated user who can interact with the draft restoration functionality can potentially exploit the flaw.

What is the safest general fix pattern for this vulnerability class?

The safest pattern is to enforce strict, server-side authorization checks on every operation that involves object identifiers. For draft restoration, this means ensuring that the authenticated user either owns the draft or has an explicit permission that allows restoring it, before performing any action.
