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\nThe distribution includes HTTP::session::ID::MD5 which contains a similar flaw, but uses the MD5 hash instead."
