Details

Unlimited transforms allowed for signed nodes ### 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. ### References https://github.com/node-saml/passport-saml/pull/595
