Description

passport-saml-encrypted through 0.1.13 contains an XML signature wrapping vulnerability where signature verification and assertion extraction use independent XPath lookups with no cross-validation. Attackers holding any validly signed SAML message can prepend a forged unsigned assertion that gets accepted as the verified identity while the genuine signature validates against the original assertion.
