Published: 5/14/2019Modified: 11/8/2023
Also known as:GHSA-54mg-vgrp-mwx9
Description
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.
Affected packages (3)
