Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability was found in Nanjing Xingyuantu Technology SparkShop up to 1.1.6. It has been rated as critical. This issue affects some unknown processing of the file /api/Common/uploadFile. The manipulation of the argument file leads to unrestricted upload. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-271403.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Unrestricted file upload vulnerability in the /api/Common/uploadFile endpoint of SparkShop e-commerce software up to version 1.1.6. The lack of proper validation on the 'file' argument allows attackers to upload arbitrary files, potentially leading to remote code execution if executable files are placed in web-accessible locations.

MitigationImplement strict allowlist-based file type validation (extension and MIME type), verify file content using magic bytes, store uploads outside webroot, disable script execution in upload directories, and apply vendor patch when available.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify SparkShop installation
    Locate the SparkShop installation directory and check for composer.json, package.json, or other project identification files that confirm the application is SparkShop.
    Affected if The application is confirmed to be SparkShop e-commerce software.
  2. Determine installed version
    Check the version file (such as version.php, composer.json, or a dedicated version config) to identify the exact version number installed.
    Affected if The installed version is 1.1.6 or any version lower than 1.1.6.
  3. Verify upload endpoint exists
    Inspect the application source code for the /api/Common/uploadFile endpoint or route handler. This is typically found in the routes/api.php file or in a Common controller handling file uploads.
    Affected if The /api/Common/uploadFile endpoint exists and is accessible without authentication.
  4. Check file type validation
    Examine the uploadFile endpoint handler code to see if there is any extension, MIME type, or magic byte validation on the 'file' parameter.
    Affected if No allowlist-based file type validation is present, or validation can be easily bypassed.
  5. Verify upload storage location
    Check the application configuration to determine where uploaded files are stored. Inspect the web server configuration to confirm if that storage directory is web-accessible.
    Affected if Uploaded files are stored in a directory accessible via HTTP/HTTPS and script execution is not disabled.

A user is affected if they are running SparkShop version 1.1.6 or lower AND the /api/Common/uploadFile endpoint is accessible without proper file type validation AND uploaded files are stored in a web-accessible location.
