CVE-2023-22936Network attack vector

Authenticated blind SSRF via search_listener parameter

Published Feb 14, 2023 · Updated Feb 28, 2025

Blind SSRF in Splunk Web allows remote authenticated users to make server-side requests from affected Splunk Enterprise and Cloud instances. The search_listener parameter accepts a destination without sufficient validation, causing the server to issue a blind outbound request. The user must hold the search capability, and the response remains hidden unless an additional vulnerability is present.
