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

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

Severity ?
7.5 (High)
CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
