Samlify vulnerable to Authentication Bypass by allowing tokens to be reused with different usernames
Quick fix
GHSA-8jjf-w7j6-323c — samlify: upgrade to the fixed version with the command below.
npm install samlify@2.4.0-rc5Details
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
