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 path traversal vulnerability in the WYSIWYG editor for Magento 2.1 prior to 2.1.18, Magento 2.2 prior to 2.2.9, Magento 2.3 prior to 2.3.2 could result in unauthorized access to uploaded images due to insufficient access control.

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

A path traversal vulnerability exists in the WYSIWYG editor for Magento versions 2.1 prior to 2.1.18, 2.2 prior to 2.2.9, and 2.3 prior to 2.3.2. The vulnerability allows attackers to traverse directories and access uploaded images outside the intended directory due to insufficient access control validation on file paths.

MitigationUpgrade to Magento version 2.1.18, 2.2.9, 2.3.2 or later. Until patched, restrict administrative access to the WYSIWYG editor and consider network-level restrictions to minimize exposure.

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 installed Magento version
    Run the CLI command 'php bin/magento --version' or check the composer.json file in the Magento root directory for the installed version.
    Affected if The installed version falls within 2.1.0 to 2.1.17, 2.2.0 to 2.2.8, or 2.3.0 to 2.3.1.
  2. Confirm WYSIWYG editor is enabled
    Log into the Magento Admin panel and navigate to Stores > Configuration > General > Content Management > WYSIWYG Options, or check the core_config_data table for the 'cms/wysiwyg/enabled' configuration value.
    Affected if WYSIWYG editor is set to Enabled (any option other than 'Disabled').
  3. Check for untrusted file upload capabilities
    Verify if the WYSIWYG editor allows image uploads in CMS pages, blocks, or product descriptions. Attempt to access the editor in the Admin panel under Content > Pages, Blocks, or Products.
    Affected if The WYSIWYG editor is accessible and allows image/file uploads to untrusted users.
  4. Inspect web server access controls
    Review the web server configuration (Apache .htaccess or Nginx configuration) and Magento admin URL access controls to determine if the WYSIWYG upload functionality is exposed to unauthenticated users.
    Affected if The WYSIWYG upload endpoints are accessible without authentication or from untrusted network locations.

You are affected if your Magento installation runs version 2.1.0-2.1.17, 2.2.0-2.2.8, or 2.3.0-2.3.1 AND the WYSIWYG editor is enabled and accessible to untrusted users.
