DescriptionGitHub Advisory

ChurchCRM is an open-source church management system. Prior to 7.1.0, an SQL injection vulnerability was identified in /EventNames.php in ChurchCRM. Authenticated users with AddEvent privileges can inject SQL via the newEvtTypeCntLst parameter during event type creation. The vulnerable flow reaches an ON DUPLICATE KEY UPDATE clause where unescaped user input is interpolated directly. This vulnerability is fixed in 7.1.0.

AnalysisAI

SQL injection in ChurchCRM /EventNames.php allows authenticated users with AddEvent privileges to execute arbitrary SQL commands via the newEvtTypeCntLst parameter during event type creation. The vulnerability reaches an ON DUPLICATE KEY UPDATE clause where user input is interpolated without sanitization, enabling high-impact database manipulation. Affects all versions prior to 7.1.0. No public exploit identified at time of analysis, though EPSS data not available. Attack requires low-privilege authenticated access but presents high confidentiality, integrity, and availability risk (CVSS 8.8).

Technical ContextAI

ChurchCRM is a PHP-based open-source church management system. This vulnerability stems from CWE-89 (SQL Injection), occurring specifically in the EventNames.php component during event type creation workflows. The flaw exists in an ON DUPLICATE KEY UPDATE SQL clause, a MySQL-specific syntax used to handle duplicate key conflicts during INSERT operations. User-controlled input from the newEvtTypeCntLst parameter is concatenated directly into the SQL statement without proper parameterization or escaping. This allows authenticated attackers to break out of the intended query context and inject arbitrary SQL commands. The affected product identifier is cpe:2.3:a:churchcrm:crm:*:*:*:*:*:*:*:*, indicating the core ChurchCRM application across versions preceding the patch. The vulnerability is classified as a classic second-order SQL injection where user input flows through application logic into a database update operation without adequate input validation or prepared statement usage.

RemediationAI

Vendor-released patch: upgrade to ChurchCRM version 7.1.0 or later, which contains the complete fix for this SQL injection vulnerability. The patch implements proper input sanitization and parameterized queries for the newEvtTypeCntLst parameter in EventNames.php. Organizations should prioritize this upgrade, particularly in environments where multiple users possess AddEvent privileges or where access controls cannot be strictly verified. Until patching is complete, temporary risk reduction measures include restricting AddEvent privileges to only highly trusted administrators, implementing enhanced database activity monitoring for suspicious queries targeting event-related tables, and reviewing audit logs for unauthorized event type creation attempts. Complete remediation details and upgrade instructions are available in the GitHub security advisory at https://github.com/ChurchCRM/CRM/security/advisories/GHSA-ggfm-5q4w-p93g. No effective workarounds exist that maintain full application functionality while eliminating the vulnerability-upgrading to 7.1.0 is the only complete remediation path.
