Technical description
passport-wsfed-saml2 provides passport strategy for both WS-fed and SAML2 protocol.

This can be done by adding attributes to the response. Users are affected specifically when the service provider is using `passport-wsfed-saml2` and a valid SAML Response signed by the Identity Provider can be obtained. Version 4.6.4 contains a fix for the vulnerability.
