ChurchCRM, an open-source church management system, contains a critical SQL injection vulnerability prior to version 7.1.0. The vulnerability exists in src/Reports/FundRaiserStatement.php where the $_SESSION['iCurrentFundraiser'] value is used in an unquoted numeric SQL context without proper integer validation. The issue originates from src/FundRaiserEditor.php where InputUtils::legacyFilterInputArr() is called without the 'int' type specifier. This allows attackers to potentially execute arbitrary SQL commands through the vulnerable session variable. The vulnerability has been fixed in version 7.1.0 of ChurchCRM.
