This information is of low entropy. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.\n\nPredicable session ids could allow an attacker to gain access to systems."}], "lastModified": "2025-07-17T21:15:50.197", "sourceIdentifier": "9b29abf9-4ab0-4765-b253-1875cd9b441e"}
