Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In Github.com/grafana/grafana, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

This vulnerability in Grafana's datasource proxy API allows authorization checks to be bypassed by adding an extra slash character in the URL path. Users with minimal permissions could gain unauthorized read access to GET endpoints in Alertmanager and Prometheus datasources. The issue primarily affects datasources that implement route-specific permissions, including Alertmanager and certain Prometheus-based datasources.
