CVE-2022-3613Public exploitNetwork attack vector

Prometheus denial of service via unrestricted PromQL

Published Jan 12, 2023 · Updated Apr 8, 2025

Denial of service in GitLab CE/EE before 15.5.7, 15.6 through 15.6.3, and 15.7 through 15.7.1 allows remote attackers to hang Prometheus. The public-project Grafana proxy accepts arbitrary PromQL and forwards concurrent, cache-busted queries through an administrative Grafana data source without limiting query complexity. A public project with a configured Grafana integration is enough; repeated expensive range queries can pin all CPU cores and leave Prometheus unresponsive.
