CVE-2025-66313 – ChurchCRM vulnerable to a time-based blind SQL injection via the 1FieldSec parameter

CVE ID : CVE-2025-66313

Published : Dec. 1, 2025, 11:15 p.m. | 1 hour, 9 minutes ago

Description : 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.

Severity: 5.1 | MEDIUM
