Question

An AI agent added an admin-only endpoint to delete any user. The product spec says only users with the `admin` role may call it. Auth middleware sets `req.user` from a verified JWT. The reviewer is checking whether the authorization is correct.

javascript
app.delete("/api/admin/users/:id", requireAuth, async (req, res) => {  // role check  const roles = req.user.roles || [];  if (roles.includes("admin") || req.query.force === "true") {    await db.user.delete({ where: { id: req.params.id } });    return res.json({ deleted: true });  }  return res.status(403).json({ error: "forbidden" });});
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.
