Critical

VectorAV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N
Name of the Vulnerable Software and Affected Versions Node-SAML versions 5.0.1 and below
Description Node-SAML improperly loads the assertion from the unsigned original response document, differing from the parts verified during signature checking. This allows modification of authentication details within a valid SAML assertion. An attacker could, for example, remove characters from the username within the SAML assertion. Exploitation requires a validly signed document from the identity provider (IdP).
Recommendations Update to version 5.1.0 or later.
