Overview
samlify is a Highly configuarable Node.js SAML 2.0 library for Single Sign On.
Affected versions of this package are vulnerable to XML Injection via the replaceTagsByValue() function. An attacker can inject arbitrary XML markup into SAML assertions by supplying crafted attribute values, leading to unauthorized attribute creation and privilege escalation when these attributes are used for authorization.
