Question

An AI assistant wrote this Python helper to hash user passwords before storing them. It runs and produces a hash. On review, what security problems should you flag, and why does 'it produces a hash' not mean it's safe?

python
import hashlibSECRET_SALT = "s3cr3t-salt-123"def hash_password(pw):    return hashlib.md5((pw + SECRET_SALT).encode()).hexdigest()
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.
