medium Nessus Plugin ID 304687

Synopsis

The remote host is affected by an information disclosure vulnerability.

Description

The version of Grafana installed on the remote host is 9.3.x through 11.6.x prior to 11.6.14, 12.0.x through 12.1.x prior to 12.1.10, 12.2.x prior to 12.2.8, 12.3.x prior to 12.3.6, or 12.4.x prior to 12.4.2. It is, therefore, affected by an information disclosure vulnerability:

 - When using public dashboards and direct data-sources, all direct data-sources' passwords are exposed despite not being used in dashboards. No passwords of proxied data-sources are exposed. (CVE-2026-27877)

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 to 11.6.14, 12.1.10, 12.2.8, 12.3.6, 12.4.2 or later.
