CVE-2026-76298: Splunk Enterprise hardcoded cryptographic key in PostgreSQL sidecar

CVE-2026-76298 · Severity: high · CVSS 8.8 · Published 2026-10-21

Splunk Enterprise is a data analytics platform used to search and monitor IT infrastructure logs. A non-administrative user can derive the database superuser password by reading the cluster identifier in logs, then use it to run arbitrary system commands on the search head cluster. This allows unauthorized code execution with the privileges of the Splunk user account.

Technical details

The PostgreSQL sidecar service derives its privileged database password from the search head cluster identifier that appears in search job logs, exposing it to non-admin users. An attacker with access to search logs but without admin or power roles can extract this hardcoded cryptographic key and leverage it to authenticate to the database and execute OS commands. The vulnerability affects Splunk Enterprise versions before 10.4.4, 10.2.8, 10.0.11, and 9.4.16.

Affected products

Splunk Enterprise 10.4.0-10.4.3, 10.2.0-10.2.7, 10.0.0-10.0.10, 9.4.0-9.4.15
