GHSA-54MG-VGRP-MWX9 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in Ratpack

Ratpack versions before 1.6.1 generate a session ID using a cryptographically weak PRNG in the JDK's ThreadLocalRandom. This means that if an attacker can determine a small window for the server start time and obtain a session ID value, they can theoretically determine the sequence of session IDs...
