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
Unrestricted Upload of File with Dangerous Type vulnerability in Pie Register.This issue affects Pie Register: from n/a through 3.8.3.1.

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 · moderate confidence

Unrestricted file upload vulnerability in the Pie Register WordPress plugin (versions through 3.8.3.1) allows attackers to upload files with dangerous types (likely executable files like PHP), potentially enabling remote code execution on the server.

MitigationImplement strict file type validation (whitelist allowed extensions/MIME types), validate actual file content rather than just extension, and store uploads outside the web root or with renamed non-executable filenames.

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. Verify Pie Register plugin is installed
    Check your WordPress plugins directory or WordPress admin dashboard for the Pie Register plugin
    Affected if The plugin is present in the WordPress installation
  2. Check installed plugin version
    Inspect the plugin header in the main plugin file or the readme.txt file within the pie-register plugin directory. Compare the version number against the affected range (< 3.8.3.3)
    Affected if The installed version is lower than 3.8.3.3 (e.g., 3.8.3.1, 3.8.3, 3.8.2, etc.)
  3. Confirm file upload feature is enabled
    Review the plugin settings in WordPress admin. Look for registration forms that include file upload fields, which is the feature vulnerable to unrestricted upload
    Affected if Any registration form has file upload fields enabled and the version is below 3.8.3.3
  4. Verify uploads directory is web-accessible
    Check the configured upload directory for the plugin (typically within wp-content/uploads/). Confirm the directory structure allows direct access to uploaded files via HTTP
    Affected if Uploaded files can be accessed directly over the web and the version is vulnerable

You are affected if Pie Register plugin is installed with a version lower than 3.8.3.3 and file upload functionality is enabled in any registration form.

Pie Register 3.8.3.3 or later

  1. Backup the WordPress site and database before making any changes
  2. Update Pie Register plugin to version 3.8.3.3 or later through the WordPress admin dashboard (Plugins > Updates) or via FTP/SSH by uploading the new version
  3. Verify the plugin version is 3.8.3.3 or higher in the installed plugins list
  4. Test user registration functionality to ensure the update did not break legitimate features
