An authenticated user with permission to query a SQL data source can bypass the fix for CVE-2026-33375 by injecting the timeGroup macro through a WHERE clause, which Grafana's regex-based macro parsing does not reject. Evaluating the injected macro causes uncontrolled memory consumption that can terminate the Grafana server process, resulting in a denial of service. The Microsoft SQL Server, PostgreSQL, and MySQL data sources are affected.

    - Build only for SUSE distributions

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

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

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

  - An authenticated user with permission to query a SQL data source can bypass the fix for CVE-2026-33375 by     injecting the timeGroup macro through a WHERE clause, which Grafana's regex-based macro parsing does not     reject. Evaluating the injected macro causes uncontrolled memory consumption that can terminate the     Grafana server process, resulting in a denial of service. The Microsoft SQL Server, PostgreSQL, and MySQL     data sources are affected. (CVE-2026-19475)

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