Executive Summary

Grafana has patched a vulnerability in its AI feature that could have allowed attackers to leak sensitive user data. The flaw enabled prompt injection attacks where malicious instructions were hidden on attacker-controlled web pages, causing the AI to ingest seemingly benign orders that actually extracted and returned confidential data to the attacker's server. This vulnerability poses a risk to data confidentiality and could potentially expose sensitive metrics, dashboards, or user information. Organizations using Grafana's AI capabilities should ensure they have updated to the patched version. Mitigation includes promptly applying security updates, restricting AI access to sensitive resources, and monitoring for suspicious data access patterns.

Summary

By hiding malicious instructions on an attacker-controlled Web page, AI could ingest orders that appear benign but return sensitive data to the attacker's server.
