Samlify vulnerable to Authentication Bypass by allowing tokens to be reused with different usernames
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
