TencentOS Server 4: grafana (TSSA-2026:0962)

high Nessus Plugin ID 343523

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0962 advisory.

 Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

 CVE-2026-17183:
 An authenticated organization user who can create or edit alert rules in a folder can query a datasource for which they do not have datasources:query permission, by setting the client-controlled query field queryType to __expr__ while retaining the UID of a real datasource, bypassing datasource permission enforcement in Grafana's Unified Alerting (ngalert).

Tenable has extracted the preceding description block directly from the Tencent Linux 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.
