Grafana security release: Critical and high severity security fixes for CVE-2026-27876 and CVE-2026-27880

Grafana has released versions 12.4.2, 12.3.6, 12.2.8, 12.1.10, and 11.6.14 to address critical and high-severity security vulnerabilities (CVE-2026-27876 & CVE-2026-27880). CVE-2026-27876 allows potential remote code execution via the SQL expressions feature, while CVE-2026-27880 creates a denial-of-service risk through an unauthenticated endpoint; upgrading to the latest versions is strongly recommended. Workarounds are available, but a full upgrade is the preferred solution for both issues.
