Which versions of Grafana are affected by EUVD-2026-16634?

A critical remote code execution vulnerability in Grafana enables authenticated administrators to achieve complete system compromise through a chained SQL expression attack.. A patch is available.

How to fix or mitigate EUVD-2026-16634?

Within 24 hours: Audit all Grafana instances for sqlExpressions feature toggle status and disable the feature immediately on all affected deployments; restrict administrative access to Grafana to only essential personnel and enforce multi-factor authentication on all admin accounts. Within 7 days: Review access logs for suspicious administrative activity and credential compromise indicators; identify and isolate any Grafana Enterprise plugin deployments tied to SQL expression functionality. Within 30 days: Monitor Grafana security advisories for patch release; deploy patched versions to all instances as soon as vendor releases a fix, prioritizing Enterprise deployments.

CRITICAL 9.1

DescriptionCVE.org

A chained attack via SQL Expressions and a Grafana Enterprise plugin can lead to a remote arbitrary code execution impact (RCE). This is enabled by a feature in Grafana (OSS), so all users are always recommended to update to avoid future attack vectors going this path.

Only instances with the sqlExpressions feature toggle enabled are vulnerable.

AnalysisAI

Remote code execution is achievable in Grafana installations through a chained attack combining SQL Expressions with a Grafana Enterprise plugin, affecting both open-source and Enterprise deployments. The vulnerability requires high-privilege authenticated access (PR:H) but enables cross-scope impact with complete system compromise once exploited. Only instances with the sqlExpressions feature toggle enabled are vulnerable, though Grafana recommends all users update to prevent future exploitation paths using this attack vector. No public exploit identified at time of analysis, and authentication as a high-privilege user is required per CVSS vector.

Technical ContextAI

This vulnerability affects Grafana Enterprise and related products as identified by CPE cpe:2.3:a:grafana:grafana_enterprise:*:*:*:*:*:*:*:*. The attack chain leverages the SQL Expressions feature in Grafana OSS combined with functionality in a Grafana Enterprise plugin to achieve arbitrary code execution. SQL Expressions is a feature toggle that enables SQL-based data transformations and queries within Grafana dashboards. The chained nature indicates multiple components must interact to create the exploitable condition, suggesting the vulnerability arises from inadequate input validation or sandboxing across plugin boundaries when SQL expressions are processed. The Changed scope (S:C) in the CVSS vector indicates the vulnerability can affect resources beyond its original security context, typical of code execution flaws that break out of application containment.

RemediationAI

Update Grafana installations to the patched version specified in the Grafana security advisory at https://grafana.com/security/security-advisories/cve-2026-27876. Patch available per vendor advisory, though specific fixed version numbers are not provided in the intelligence data. As an interim mitigation for environments unable to patch immediately, disable the sqlExpressions feature toggle to eliminate the attack vector. Additionally, audit and restrict administrative access privileges to minimize the pool of accounts with PR:H level permissions capable of exploiting this vulnerability. Review Grafana Enterprise plugin configurations to identify and assess risk from plugin interactions with SQL Expressions functionality.
