Overview

github.com/crewjam/saml/samlsp is a package that contains a partial implementation of the SAML standard in golang. SAML is a standard for identity federation, i.e. either allowing a third party to authenticate your users or allowing third parties to rely on us to authenticate their users.

Affected versions of this package are vulnerable to Authentication Bypass. It allows an attacker to bypass SAML Authentication.
