CVE-2022-43565Network attack vector

Risky-command safeguards bypass via tstats JSON mishandling

Published Nov 4, 2022 · Updated May 5, 2025

Improper input validation in Splunk Enterprise 8.1.0 through 8.1.11 and 8.2.0 through 8.2.8 allows remote attackers to bypass SPL safeguards. The tstats command mishandles JSON input and allows a crafted browser request to evade controls that normally restrict risky search commands. Exploitation requires phishing a highly privileged user into initiating the request in a browser, and impact is limited to actions available through that user's risky-command permissions.
