An XML Signature Wrapping vulnerability exists in Samlify 2.2.0 and earlier, and in predecessor Express-saml2 which could allow attackers to impersonate arbitrary users.

Versions of `samlify` prior to 2.4.0-rc5 are vulnerable to Authentication Bypass. The package fails to prevent XML Signature Wrapping, allowing tokens to be reused with different usernames. A remote attacker can modify SAML content for a SAML service provider without invalidating the cryptographic signature, which may allow attackers to bypass primary authentication for the affected SAML service provider. ## Recommendation Upgrade to version 2.4.0-rc5 or later
