Technical details

A malformed SAML message sent to endpoints serving the identity-provider or SAML source role triggers an unhandled exception that terminates the worker process. While sessions survive the crash due to database persistence, repeated attacks can sustain a denial of service against a fraction of traffic. The vulnerability is specific to SAML protocol implementations and requires network access to the affected endpoints.
