Service interruption via undefined-route metrics collection
Published Mar 31, 2025 · Updated Jun 25, 2026
Uncontrolled resource consumption in Red Hat OpenShift Lightspeed allows remote attackers to interrupt service via unauthenticated API requests. The REST API counter middleware labels and records metrics for arbitrary undefined route paths instead of ignoring them, creating attacker-controlled time series. No authentication or user interaction is required; repeated requests exhaust CPU, memory, and disk and degrade the application and cluster.

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.
