QID 981788

QID 981788: Java (maven) Security Update for io.ratpack:ratpack-groovy (GHSA-54mg-vgrp-mwx9)

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.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.

CVSS V3 rated as Medium - 3.7 severity.

CVSS V2 rated as Medium - 4.3 severity.
