Grafana Prometheus Data Source Path Traversal Vulnerability

Publication date: 2026-11-12

Last updated on: 2026-11-12

Assigner: Grafana Labs

Description
Grafana's Prometheus data source passes the resource path supplied by the caller to the configured Prometheus server without restricting it to the supported API endpoints [missing path allowlist]. A user with permission to query the data source can read responses from other endpoints on that server using the data source's credentials.

Executive Summary

Grafana's Prometheus data source does not restrict resource paths provided by users to valid API endpoints. This allows users with query permissions to access unintended endpoints on the Prometheus server using the data source's credentials.

Impact Analysis

An attacker with access to query the data source could read sensitive data from other endpoints on the Prometheus server, potentially exposing internal metrics or other confidential information.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, violating confidentiality requirements in GDPR and HIPAA. Organizations using Grafana with Prometheus may face compliance violations if sensitive data is accessed.

Mitigation Strategies

Update Grafana to the latest version that patches this vulnerability. Restrict user permissions to prevent unauthorized access to the Prometheus data source. Review and audit all data source configurations to ensure no sensitive endpoints are exposed.
