CVE-2025-66313: Churchcrm

High severity, CVSS 7.2. EPSS: 0.4% chance of exploitation in the next 30 days.

ChurchCRM is an open-source church management system. In ChurchCRM 6.2.0 and earlier, there is a time-based blind SQL injection in the handling of the 1FieldSec parameter. Injecting SLEEP() causes deterministic server-side delays, proving the value is incorporated into a SQL query without proper parameterization. The issue allows data exfiltration and modification via blind techniques.

Affected products

• Churchcrm Churchcrm: up to and including 6.2.0
