Affected packages
• npm node-saml: < 4.0.0-beta.5 → fixed in 4.0.0-beta.5
Description
Impact
A remote attacker may be able to bypass SAML authentication on a website using passport-saml. A successful attack requires that the attacker is in possession of an arbitrary IDP signed XML element. 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.
Patches
Users should upgrade to node-saml v4.0.0-beta5 or newer.
Workarounds
Disable SAML authentication.
