Description Pedro Sampaio 2018-03-08 18:02:34 UTC
Affected versions of this package are vulnerable to Signature Validation Bypass. It allows a remote attacker to construct a crafted SAML assertion on behalf of an Identity Provider that would pass as cryptographically valid, thereby allows them to impersonate a user from that Identity Provider, aka a key confusion issue.
