Attackers Can Leverage Grafana’s AI Features to Bypass Safeguards and Exfiltrate Sensitive Information

Researchers at Noma Security have identified a critical vulnerability in Grafana, a popular open-source analytics and visualization platform, which enables attackers to bypass client-side protections and security guardrails and exfiltrate sensitive information.

The Vulnerability: GrafanaGhost

The vulnerability, dubbed GrafanaGhost, arises from the way Grafana’s AI components process information, allowing attackers to link private data to external servers and expose sensitive information without user interaction.

“The data leaks the moment the system tries to display the image,” Noma noted.Further, the researchers found that attackers can fake the path of any company using Grafana by guessing the data structure and model. Additionally, they can leverage the application’s data store to abuse Grafana to exfiltrate data via image tags by crafting their prompts accordingly.

Response and Mitigation

In response to the discovery, Grafana took immediate action to address the vulnerabilities. However, experts caution that the exploitability of this vulnerability depends heavily on deployment specifics, such as whether AI features are enabled, whether egress controls are in place, and how the environment handles external data ingestion.

Experts emphasize the importance of implementing network-level URL blocking and hardening AI against prompt injection to mitigate this type of vulnerability. “Perimeter controls are insufficient, and the only way to secure AI-driven tooling is to perform runtime behavioral monitoring of what it actually does,” said Ram Varadarajan, CEO of Acalvio.

Conclusion

The GrafanaGhost vulnerability serves as a reminder of the potential risks associated with AI-powered systems and highlights the need for continued vigilance and proactive measures to ensure the security of these systems.
