DescriptionGitHub Advisory

Executive ViewAI

Why It Matters

Chartbrew versions prior to 4.8.1 contain a remote code execution vulnerability that could allow attackers to execute arbitrary code on systems running this data visualization platform. Organizations using Chartbrew for business intelligence and reporting face potential data compromise, system takeover, and operational disruption, particularly if the application processes sensitive business data or connects to critical databases.

Business Impact: High

Compensating Controls

Disable MongoDB dataset query feature if not critical to operations; implement Web Application Firewall (WAF) rules to block suspicious query parameters and code injection patterns; restrict network access via firewall rules to limit which systems can reach Chartbrew; apply input validation and sanitization at the application layer; segment Chartbrew instances on isolated networks with minimal database connectivity; monitor database and application logs for unauthorized access attempts; consider running Chartbrew in a sandboxed container environment with limited privileges until patched.
