Grafana Labs 11.6.x < 12.4.12 / 13.0.x < 13.0.10 / 13.1.x < 13.1.7 / 13.2.x < 13.2.3 Missing Authorization (CVE-2026-81841)

medium Nessus Plugin ID 362625

Synopsis

The remote host is affected by a missing authorization vulnerability.

Description

The version of Grafana Labs installed on the remote host is 11.6.x through 12.4.x prior to 12.4.12, or 13.0.x prior to 13.0.10, or 13.1.x prior to 13.1.7, or 13.2.x prior to 13.2.3. It is, therefore, affected by a missing authorization vulnerability:

- Pausing a shared (public) dashboard did not revoke its access token for the endpoints that serve frontend bootstrap data. Anyone holding the link to a paused shared dashboard could still retrieve, without authenticating, the configuration of the dashboard's data sources, including stored credentials for data sources using browser access (missing authorization). Deleting the shared dashboard does revoke the token. (CVE-2026-81841)

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

Solution

Update Grafana Labs to 12.4.12, 13.0.10, 13.1.7, 13.2.3 or later.
