LeakyLooker: Nine Cross-Tenant Flaws in Looker Studio
🔒 Tenable Research disclosed nine cross-tenant vulnerabilities, collectively named LeakyLooker, in Looker Studio that could allow attackers to run arbitrary SQL and access datasets across tenants. The flaws affected connectors including BigQuery, Spanner, PostgreSQL, MySQL, Google Sheets and Cloud Storage and involved SQL injection, data leaks via report elements and a BigQuery denial-of-wallet issue. Google has applied global fixes to its fully managed service and no customer action is required, though organisations should review sharing settings and limit unused connectors.
