What is CVE-2026-56221?

Cap-go versions prior to 12.128.2 are susceptible to multiple SQL injection vulnerabilities found in the Cloudflare Analytics Engine. These vulnerabilities occur when user-controlled data from API request bodies is directly incorporated into SQL query strings without adequate sanitization or parameterization. Authenticated users possessing read-level API key permissions can exploit this weakness by injecting arbitrary SQL through parameters such as deviceIds, search, version_name, cursor, and actions. This may enable them to access sensitive analytics data belonging to other users or applications, posing a significant risk to data integrity and privacy.
