Question

An AI agent added a new Express endpoint to let users delete their account. It works when you test it logged in. Reviewing the diff, what security check is missing, and how would you confirm the gap before this ships?

1router.post('/account/delete', async (req, res) => {2  const { userId } = req.body;3  await db.users.delete({ id: userId });4  res.json({ ok: true });5});

What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
