title: Denial Of Service due to Untrusted XML Tag in XML Parser within  SAML Authentication
description: On Splunk Enterprise versions below 9.0.5, 8.2.11, and 8.1.14, an unauthenticated attacker can send specially-crafted messages to the XML parser within SAML authentication to cause a denial of service in the Splunk daemon.
problem types: The software processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
