## What is CVE-2025-66395?

CVE-2025-66395 is a high-severity SQL injection vulnerability in Churchcrm Churchcrm, published on 17 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

ChurchCRM is an open-source church management system. Prior to version 6.5.3, a SQL injection vulnerability exists in the `src/ListEvents.php` file. When filtering events by type, the `WhichType` POST parameter is not properly sanitized or type-casted before being used in multiple SQL queries. This allows any authenticated user to execute arbitrary SQL commands, including time-based blind SQL injection attacks. Any authenticated user, regardless of their privilege level, can execute arbitrary queries on the database. This could allow them to exfiltrate, modify, or delete any data in the database, including user credentials, financial data, and personal information, leading to a full compromise of the application's data. Version 6.5.3 fixes the issue.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
