Why Use App-Level Auth When Every Database Has Auth? (Splunk Enterprise CVE-2026-20253 Pre-Auth RCE)
Splunk published CVE-2026-20253, a pre-authentication remote code execution vulnerability in the PostgreSQL Sidecar Service with a CVSS score of 9.8. The vulnerability affects Splunk Enterprise version 10 and above, with Splunk Enterprise on AWS being vulnerable by default, while on-premises Windows installations require the sidecar to be explicitly enabled. The researchers analyzed the vulnerable service listening on local ports and confirmed the exposure in default deployments.
Why it matters: Organizations running Splunk Enterprise on AWS with version 10 or higher face immediate remote code execution risk without authentication; security teams should verify their Splunk deployment type and version, then apply patches or disable the PostgreSQL Sidecar Service if not needed.
