What is CVE-2025-66395?

ChurchCRM, an open-source church management system, is vulnerable to SQL injection due to improper sanitization of user input in the WhichType POST parameter in the src/ListEvents.php file. This flaw allows any authenticated user to leverage the vulnerability to execute arbitrary SQL commands. Consequently, an attacker can potentially exfiltrate, alter, or delete sensitive data within the database, including user credentials and financial information. The issue affects all versions prior to 6.5.3, which includes a patch to resolve this critical security gap.
