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 Themify Shopo allows Upload a Web Shell to a Web Server.This issue affects Shopo: from n/a through 1.1.4.

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

Themify Shopo plugin versions up to 1.1.4 contain an unrestricted file upload vulnerability allowing authenticated attackers to upload dangerous file types (e.g., PHP web shells) directly to the web server, enabling remote code execution.

MitigationImplement strict allowlist-based file type validation using magic byte inspection, store uploaded files outside the webroot or with restricted execution permissions, and remove executable permissions on the upload directory.

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 Themify Shopo plugin is installed
    Access WordPress admin dashboard and navigate to Plugins > Installed Plugins, or inspect the /wp-content/plugins/ directory for a themify-shopo folder
    Affected if The plugin folder themify-shopo exists in the WordPress plugins directory
  2. Check installed plugin version
    In WordPress admin, find the Themify Shopo entry in the plugin list and note the version number displayed, or read the main plugin PHP file header for the Version field
    Affected if The version number is 1.1.4 or lower (the vulnerability affects versions up to and including 1.1.4)
  3. Confirm file upload functionality is accessible
    Identify if the plugin exposes any file upload endpoints. Check plugin settings for upload features, or review publicly accessible AJAX actions or form handlers that process file uploads. Typical paths include /wp-admin/admin-ajax.php actions or frontend forms
    Affected if The plugin has an active file upload feature that accepts files without proper validation
  4. Inspect upload directory permissions and contents
    Locate the upload directory used by the plugin (commonly /wp-content/uploads/ or a plugin-specific subdirectory). List all files and check for unexpected file types such as .php, .phtml, .php5, .js, or other executable extensions
    Affected if The upload directory contains files with executable extensions, especially PHP files from unknown sources
  5. Review recent server access logs for upload activity
    Examine web server access logs (Apache error.log, access.log or Nginx logs) for POST requests to plugin file upload handlers. Look for unusual file types being uploaded to the uploads directory
    Affected if Logs show suspicious file uploads with executable extensions to plugin-related endpoints

A user is affected if the Themify Shopo plugin version 1.1.4 or lower is installed AND the file upload feature is accessible and actively processing uploads without proper validation.
