FreeBSD : Grafana -- RCE on Grafana via sqlExpressions (f45ad940-58ff-11f1-b525-3c7c3fba4204)

critical Nessus Plugin ID 317068

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the f45ad940-58ff-11f1-b525-3c7c3fba4204 advisory.

https://grafana.com/security/security-advisories/cve-2026-27876 reports:
A chained attack via SQL Expressions and a Grafana Enterprise plugin can lead to a remote arbitrary code execution impact (RCE). This is enabled by a feature in Grafana (OSS), so all users are always recommended to update to avoid future attack vectors going this path.

Only instances with the sqlExpressions feature toggle enabled are vulnerable.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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

Solution

Update the affected packages.
