Access Restriction Bypass

passport-wsfed-saml2 is a SAML2 Protocol and WS-Fed library.

Affected versions of this package are vulnerable to Access Restriction Bypass when a remote attacker can bypass WSFed authentication on a website. A successful attack requires that the attacker has an arbitrary IDP-signed assertion.

NOTE Depending on the IDP used, fully unauthenticated attacks (e.g, without access to a valid user) might also be feasible if the generation of a signed message can be triggered.

How to fix Access Restriction Bypass?

A fix was pushed into the master branch but not yet published.
