Overview

samlify is a Highly configuarable Node.js SAML 2.0 library for Single Sign On.

Affected versions of this package are vulnerable to Improper Verification of Signature. An attacker could potentially wrap the signature of a SAML response, and insert a new username in the original token, making it appear as though a different user was authenticated.
