Overview

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via the onlyPathHoistNamesInternal function due to differential XML parsing. Attackers can carry out a signature bypass if they have access to certain IDP-signed messages.

Note:

Users of https://ssoready.com, the public-hosted instance of SSOReady, are unaffected.
