CVE-2026-39339

ChurchCRM has an API Authentication Bypass

ChurchCRM is an open-source church management system. Prior to 7.1.0, a critical authentication bypass vulnerability in ChurchCRM's API middleware (ChurchCRM/Slim/Middleware/AuthMiddleware.php) allows unauthenticated attackers to access all protected API endpoints by including "api/public" anywhere in the request URL, leading to complete exposure of church member data and system information. This vulnerability is fixed in 7.1.0.
