CVE-2025-20366Network attack vector

Sensitive search-result disclosure via guessed job SID

Published Oct 1, 2025 · Updated Oct 1, 2025

Improper access control in Splunk Enterprise and Splunk Cloud Platform allows remote authenticated users to retrieve private search results. The search-job results endpoint accepts a guessed SID for an administrative background job without enforcing the job's ownership and role restrictions. A non-admin, non-power user must have an account, and a matching live SID exposes only that job's potentially sensitive results.
