CVE-2022-23505: Security Update for passport-wsfed-saml2 Library

Published: Dec 12, 2022

CVE number: CVE-2022-23505

A remote attacker can bypass WSFed authentication on a website using passport-wsfed-saml2. A successful attack requires that the attacker is in possession of an arbitrary IDP signed WSFed assertion. Depending on the IDP used, fully unauthenticated attacks (e.g without access to a valid user) might also be feasible if generation of a signed message can be triggered.

You are affected if you are using WSFed protocol with the passport-wsfed-saml2 library versions  <4.6.3.

SAML2 protocol is not affected.

Upgrade to version >=4.6.3

The fix provided in the patch will not affect your users.
