Overview
Affected versions of this package are vulnerable to Open Redirect n the default SamlSingleSignOnHandler created by SamlServiceProviderBuilder. An attacker can redirect a user to an external site by supplying a RelayState value, which the default handler reflects into the HTTP Location header after the user completes authentication, without checking that it is a local path. Only applications that use the default SSO handler are affected, because an application that supplies its own ssoHandler to SamlServiceProviderBuilder controls the post-login redirect itself.
