CVE-2026-56281 Capgo CVE debrief

CVE-2026-56281 is a SQL injection vulnerability in Capgo before 12.128.2. The vulnerability exists in the POST /private/admin_stats endpoint, where the limit parameter is destructured from an unvalidated request body and interpolated directly into Cloudflare Analytics Engine SQL queries via template literals. An attacker with platform admin credentials can inject SQL fragments to enumerate dataset schemas, extract analytics data, or cause denial-of-service against the analytics backend. This vulnerability has a significant impact on the security of affected systems and should be prioritized for mitigation.

Who should care

Administrators and users of Capgo before version 12.128.2 should be aware of this vulnerability and take necessary actions to mitigate it. This includes reviewing system logs for potential SQL injection attempts and ensuring that all systems are updated to the latest version. Additionally, security teams should consider the potential impact on their systems and prioritize mitigation efforts accordingly.

Technical summary

The vulnerability is caused by the lack of validation of the limit parameter in the request body, which is then used in SQL queries. This allows an attacker to inject malicious SQL code and potentially extract or modify sensitive data. The vulnerability exists in the POST /private/admin_stats endpoint, where the limit parameter is destructured from an unvalidated request body and interpolated directly into Cloudflare Analytics Engine SQL queries via template literals.

Defensive priority

High

Recommended defensive actions

  • Update Capgo to version 12.128.2 or later
  • Validate and sanitize user input to prevent SQL injection
  • Monitor analytics backend for suspicious activity
  • Implement additional security measures to prevent exploitation
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
