Unlimited transforms allowed for signed nodes
Quick fix
GHSA-5379-r78w-42h2 — passport-saml: upgrade to the fixed version with the command below.
npm install passport-saml@3.1.0Details
### 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.
