title: Cross-Site Request Forgery in the ‘ssg/kvstore_client’ REST Endpoint in Splunk Enterprise
description: In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, a cross-site request forgery in the Splunk Secure Gateway (SSG) app in the ‘kvstore_client’ REST endpoint lets a potential attacker update SSG KV store collections using an HTTP GET request.
problem types: The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request.
