CVE-2026-56221Public exploitNetwork attack vector

Cross-tenant analytics disclosure via SQL query interpolation

Published Jun 22, 2026 · Updated Jun 22, 2026

SQL injection in Capgo before 12.128.2 allows remote authenticated users to read other tenants' analytics data through private API requests. Functions in cloudflare.ts interpolate deviceIds, search, version_name, cursor, actions, and app_id values directly into Cloudflare Analytics Engine SQL strings without parameterization or complete escaping. A read-level API key reaches the affected endpoints, and successful injection breaks application and tenant isolation for analytics data.
