HIGH 8.8
CVE-2026-76298 is a high-severity flaw (CVSS 8.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
In Splunk Enterprise versions below 10.4.4 and 10.2.8, a user who does not hold the "admin" or "power" Splunk roles could derive the PostgreSQL sidecar database superuser password and run arbitrary operating system commands as the user account running Splunk Enterprise on search head cluster members. The vulnerability is possible because the PostgreSQL sidecar service derives a privileged database password from the search head cluster identifier
