Privilege Escalation via Dashboard Permissions API in Grafana

Publication date: 2026-01-27

Last updated on: 2026-04-20

Assigner: Grafana Labs

The dashboard permissions API does not verify the target dashboard scope and only checks the dashboards.permissions:* action. As a result, a user who has permission management rights on one dashboard can read and modify permissions on other dashboards. This is an organization‑internal privilege escalation.

Executive Summary

This vulnerability occurs because the dashboard permissions API does not verify the specific dashboard scope when managing permissions. Instead, it only checks if a user has the general dashboards.permissions:* action. Consequently, a user with permission management rights on one dashboard can read and modify permissions on other dashboards within the organization, leading to an internal privilege escalation.

Impact Analysis

This vulnerability can allow a user with permission management rights on a single dashboard to escalate their privileges and access or modify permissions on other dashboards within the organization. This could lead to unauthorized access, modification of sensitive data, and potential disruption of dashboard configurations.
