A security vulnerability in the /apis/dashboard.grafana.app/* endpoints allows authenticated users to bypass dashboard and folder permissions. The vulnerability affects all API versions (v0alpha1, v1alpha1, v2alpha1). Impact: - Viewers can view all dashboards/folders regardless of permissions - Editors can view/edit/delete all dashboards/folders regardless of permissions - Editors can create dashboards in any folder regardless of permissions - Anonymous users with viewer/editor roles are similarly affected Organization isolation boundaries remain intact. The vulnerability only affects dashboard access and does not grant access to datasources.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A security vulnerability in the /apis/dashboard.grafana.app/* endpoints allows authenticated users to     bypass dashboard and folder permissions. The vulnerability affects all API versions (v0alpha1, v1alpha1,     v2alpha1). Impact: - Viewers can view all dashboards/folders regardless of permissions - Editors can     view/edit/delete all dashboards/folders regardless of permissions - Editors can create dashboards in any     folder regardless of permissions - Anonymous users with viewer/editor roles are similarly affected     Organization isolation boundaries remain intact. The vulnerability only affects dashboard access and does     not grant access to datasources. (CVE-2025-3260)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Grafana Labs installed on the remote host is affected by a vulnerability as referenced in the CVE-2025-3260 advisory. 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - The built-in XY Chart plugin is vulnerable to a DOM XSS vulnerability. A user with Editor permissions is
    able to modify such a panel in order to make it execute arbitrary JavaScript. (CVE-2025-2703)
