Runtime metadata disclosure via unauthenticated metrics
Published Aug 19, 2026 · Updated Aug 19, 2026
Information disclosure in Splunk Enterprise 10.4 before 10.4.2 allows remote attackers to read Edge Processor sidecar metrics over the network. The Edge Processor SPL2 Preview sidecar exposes its Prometheus metrics endpoint without authentication, so requests return runtime and build metadata directly from the sidecar service. Exposure requires network reachability to that sidecar endpoint and is bounded to service-detail disclosure; the advisory does not indicate direct data modification or service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
