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 Upload of File with Dangerous Type vulnerability in WP-Lister Lite for eBay allows attackers to upload dangerous file types (such as executable scripts) directly through the plugin's upload functionality. This could allow remote code execution if an attacker uploads a malicious PHP file or similar payload.

MitigationRestrict file uploads to only allow safe file types (images, documents) by implementing strict file extension and MIME type validation, checking file content/magic bytes, storing uploads outside the web root, and renaming uploaded files.

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 if WP-Lister Lite for eBay plugin is installed
    Check the WordPress plugins directory (wp-content/plugins/) for a folder related to wp-lister or wp-lister-lite, or use the WordPress admin plugins list to confirm the plugin is present
    Affected if The plugin is installed and active on the WordPress site
  2. Determine the installed version of WP-Lister Lite
    Open the plugin's main PHP file or readme.txt in the plugin folder and locate the Version header field, or query it via WordPress admin or database
    Affected if The version number falls within any known affected range or cannot be determined (treat unknown versions as potentially vulnerable)
  3. Verify if the file upload functionality is enabled
    Access the plugin settings pages in WordPress admin and look for import, CSV upload, or listing import features that accept file uploads
    Affected if The plugin exposes any file upload functionality to users or to unauthenticated attackers
  4. Check file upload permission configuration
    Review the wp-content/uploads directory permissions and the plugin settings to see if any upload capability is granted to low-privilege users or guest users
    Affected if The upload feature permits users without administrator privileges to upload files, or is accessible without authentication
  5. Inspect uploaded file storage location
    Examine the plugin code or configuration to determine where uploaded files are stored (check if stored inside web-accessible directories like /wp-content/uploads/)
    Affected if Uploaded files are stored in a web-accessible location and retain their original filename extension
  6. Test for unrestricted file type validation
    Attempt to upload a file with a potentially dangerous extension (.php, .phtml, .exe) through the plugin's upload function if you have access, or review the plugin source code to see if it validates file types
    Affected if The plugin does not perform strict file extension and MIME type validation, or does not verify file content magic bytes before saving

A user is affected if WP-Lister Lite for eBay is installed, the version is within the affected range, and the vulnerable upload functionality is accessible without proper file type restrictions.
