CVE-2026-13721 · Severity: medium · CVSS 6.5 · Published 2026-11-11

Grafana is an observability platform that allows organizations to monitor and visualize data across their infrastructure. A user with edit permissions in one folder could modify, move, or delete resources provisioned via Git Sync in other folders where they only had read-only access, effectively escalating their privileges to unintended areas.

## Technical details

An authorization bypass in the provisioning files API fails to properly validate folder-level permissions when handling Git Sync provisioned resources. A user with edit access to one folder can use the API to modify or delete resources in folders where they possess only view access, bypassing intended access controls. The vulnerability requires an authenticated user with edit permissions in at least one folder.
