Tenable Research recently uncovered “LeakyLooker,” a critical set of nine novel cross-tenant vulnerabilities within Google Looker Studio that enabled attackers to silently exfiltrate or modify sensitive data across various Google Cloud Platform services.
Following responsible disclosure by security researchers, Google has successfully patched all nine vulnerabilities globally, neutralizing the threat without requiring any manual updates from end users.
These vulnerabilities exposed highly sensitive data across numerous enterprise environments, potentially compromising any organization that actively utilizes Looker Studio data connectors.
The affected cloud integrations spanned a massive attack surface, including widely adopted services such as Google Sheets, BigQuery, Spanner, Cloud Storage, PostgreSQL, and MySQL databases.

What makes this finding significant is that it shows how even the most common cloud integrations can become a cross‑tenant attack vector. It’s not just about isolated vulnerabilities, but about the need to continuously audit the connectors and services that expand the exposure surface. Google’s quick patching of the issue is positive, but the underlying message is clear: every layer of integration is also a layer of risk.
