Question

An AI agent built a Python endpoint that fetches a URL the user provides (for a 'link preview' feature) and returns the page title. It works for normal links. What request would let an attacker abuse this, and what should you add on review?

python
import requests@app.post('/preview')def preview():    url = request.json['url']    html = requests.get(url, timeout=5).text    return {'title': extract_title(html)}
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.
