CVE-2026-19475 (GCVE-0-2026-19475)

Vulnerability from cvelistv5 – Published: 2026-09-02 15:56 – Updated: 2026-09-03 08:08

Title

SQL Data Source Plugin: OOM DoS via $__timeGroup macro

Summary

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.

Severity

6.5 (Medium)
