SQL Data Source Plugin: OOM DoS via $__timeGroup macro

6.5 MediumFix 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.

  • Bug fixes and changes:

    • Fixed scrape manager failing to reload properly when SD configuration changes rapidly.
    • Prevent memory leak in remote-write path when the receiving endpoint is unavailable.
    • Native Histograms are no longer experimental. They are fully supported for production workloads.
    • Added support for OpenTelemetry traces within the Prometheus UI to correlate metrics and traces.

    • Introduce a new UI interface for safely deleting specific time series data directly.
    • Added dynamic relabeling actions to extract substrings using regex capture groups.
