CVE-2026-106472: Grafana Prometheus data source path traversal

CVE-2026-106472 · Severity: medium · CVSS 6.3 · Published 2026-11-12

Grafana's Prometheus data source allows users with query permissions to access arbitrary endpoints on the connected Prometheus server using the data source's credentials, rather than being restricted to the intended API endpoints. An attacker could read sensitive data or configuration from the Prometheus server that should not be exposed through Grafana.

Technologies: Grafana. Vendors: Grafana.

Technical details

The Prometheus data source plugin fails to implement a path allowlist, passing user-supplied resource paths directly to the backend Prometheus server without validation. A user with permission to query the data source can enumerate and access unintended API endpoints, reading responses with the privileges of the data source's configured credentials.
