CVE-2026-76269

MEDIUM 6.5

Published 2026-10-07 · Last modified 2026-10-10

In Splunk Enterprise versions below 10.4.3, 10.2.7, 10.0.10, and 9.4.15, a user who does not hold the "admin" or "power" Splunk roles could use a user-controlled job identifier to access substantially all search job information from jobs that belong to other users, including search query text, job metadata, results, and preview results, through an Application Programming Interface (API) implemented as a Representational State Transfer (REST) API. The vulnerability is possible because the REST API does not fully validate job ownership before returning search job information.
