Is this vulnerability remotely exploitable over the internet?

Yes, if the Tandoor Recipes instance is exposed over the internet, any authenticated user with network access to the API and membership in a Space can exploit the issue via crafted HTTP requests.

Does exploitation require elevated privileges or administrator access?

No. Exploitation only requires a standard authenticated account in the same Space as the target recipes. The attacker does not need admin or special roles; normal user permissions were enough to abuse the batch update endpoint.

What is the safest general fix pattern for this kind of bug?

The most robust fix is to consolidate object-level authorization into shared, reusable checks and ensure all endpoints—especially batch or "shortcut" APIs—invoke these checks for every object ID. Treat any user-supplied identifier as untrusted and verify ownership or sharing permissions before performing updates.
