Vulnerable vs. safe
Flagged by this check
return pickle.loads(blob)Passes - the safe pattern
return json.loads(blob)Why it matters & how to fix it
Deserializing data with pickle can execute arbitrary code if the data is attacker-controlled (CWE-502). Never unpickle untrusted input. Use a safe format such as JSON, or sign/verify payloads (e.g. hmac) before loading.
