Affected versions of this package are vulnerable to Improper Authentication. For each SAML client it is possible to send an AuthnRequest message via SOAP with Basic Authorization header and Keycloak will successfully authenticate the user for the client and will not consider the authentication flow applied. The presence of the flow is hidden from the administrator, it is not possible to disable it in the client's configuration similarly as direct grant etc.
