**Name of the Vulnerable Software and Affected Versions** Yifang CMS versions up to 2.0.2 **Description** A problematic issue was found in the Admin Panel component, specifically in the `downloadFile` function of the `/api/File/downloadFile` API endpoint. The manipulation of the `File` argument leads to path traversal. This issue can be exploited remotely. **Recommendations** For Yifang CMS versions up to 2.0.2, consider disabling the `downloadFile` function of the `/api/File/downloadFile` API endpoint until a patch is available. Restrict access to the Admin Panel to minimize the risk of exploitation. Avoid using the `File` argument in the affected API endpoint until the issue is resolved.
