Is this vulnerability remotely exploitable over the internet?

Yes, if the Hoppscotch instance is exposed over the internet, any authenticated remote user who can obtain another user's environment ID can exploit the issue via the GraphQL API.

Does an attacker need elevated privileges or admin access?

No. Only standard authenticated access is required; the flaw lies in missing ownership enforcement, not in administrative permissions.

What is the safest general fix pattern for this issue?

Tie every environment operation to the authenticated user by consistently extracting the user from the auth context and ensuring all queries include both the environment ID and the user identifier (or tenant identifier) in the `WHERE` clause.
