ghsa-5379-r78w-42h2

Vulnerability from github

Published

2021-08-30 16:11

Modified

2024-02-10 00:55

Severity ?

5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L

Summary

Unlimited transforms allowed for signed nodes

Details

Impact

A malicious SAML payload can require transforms that consume significant system resources to process, thereby resulting in reduced or denied service. This would be an effective way to perform a denial-of-service attack.

Patches

This has been resolved in version 3.1.0. The resolution is to limit the number of allowable transforms to 2.
