Critical Zero-Day in Metabase Analytics Tool Could Expose Countless Business Systems

Dark Reading · 11 Aug 2026

Key Takeaway If your business uses Metabase or any third-party tool built on it, restrict external access immediately and watch closely for an official patch, since this critical flaw currently has no CVE to trigger automatic security alerts.

Security researchers have identified a serious zero-day vulnerability in Metabase, a widely used open-source business-analytics and SQL query platform. The flaw has been rated at the highest severity level and reportedly allows attackers to remotely gain administrator-level access to affected systems without needing prior credentials.

What makes this vulnerability particularly concerning is its potential 'wide blast radius.' Because Metabase is often embedded into other business tools and dashboards, a successful attack wouldn't just compromise the platform itself — it could cascade downstream to any organisation or application relying on that Metabase instance for data and reporting. At the time of reporting, no official CVE identifier had been assigned, meaning organisations may not yet see this flaw flagged in standard vulnerability scanning tools.

For small and medium businesses that use Metabase directly, or rely on third-party services built on top of it, this represents a hidden risk that traditional patch-management processes might miss. Until a CVE is issued and an official patch released, administrators should closely monitor vendor communications and restrict access to Metabase instances wherever possible.
