GHSA-5p8w-2mvw-38pv
Signature bypass via multiple root elements
Quick fix
GHSA-5p8w-2mvw-38pv — node-saml: upgrade to the fixed version with the command below.
npm install node-saml@4.0.0-beta.5Details
### 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.
