OpenEMR 是一款免费且开源的电子健康记录（EHR）与医疗诊所管理应用。在 8.3.0 版本之前， 文件通过 GET 请求执行涉及状态变更的“作废”（void）、“全部作废”（voidall）及“重新生成”（regen）操作，且未进行 CSRF（跨站请求伪造）令牌验证。其中，表单校验和（form_checksum）的完整性检查为条件性执行：当相关参数被省略时，该检查将被跳过。这允许攻击者发起跨站请求，强制已认证的计费用户作废结账记录或重新生成发票计数器。由此引发的变更可能篡改分类账状态、财务报告及审计记录。该漏

Vulnerability Title
OpenEMR: CSRF Protection Bypass on IPPF Point-of-Sale Void and Regen Operations
Source: CVE Program / CVE List V5
Vulnerability Description
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, interface/patient_file/pos_checkout_ippf.php performs state-changing void, voidall, and regen operations through GET requests without CSRF token validation. The form_checksum integrity check is conditional and is skipped when the parameter is omitted, allowing a cross-site request to force an authenticated billing user to void checkouts or regenerate invoice counters. The resulting changes can alter ledger state, financial reporting, and audit records. This issue is fixed in version 8.3.0.
