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 zozothemes Miion miion allows Upload a Web Shell to a Web Server.This issue affects Miion: from n/a through <= 1.2.7.

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

The zozothemes Miion theme version 1.2.7 and earlier contains an unrestricted file upload vulnerability that allows authenticated attackers to upload arbitrary files, including malicious PHP web shells, directly to the web server. This enables complete remote code execution on the affected system.

MitigationImplement strict allowlist-based file type validation (checking magic bytes/Content-Type, not just extensions) and store uploaded files outside the webroot or rename them to non-executable extensions with disabled script execution 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. Identify Miion theme installation
    Locate theme files in your web application's theme directory and verify the theme name is 'Miion' from zozothemes. Common paths include /wp-content/themes/miion/ (WordPress) or similar theme directories.
    Affected if The Miion theme by zozothemes is present in the application
  2. Determine installed theme version
    Open the theme's style.css, functions.php, or version.php file and locate the version declaration. Compare the version number to 1.2.7.
    Affected if The installed version is 1.2.7 or earlier
  3. Verify file upload functionality exists
    Search the theme files for upload-related code: forms with enctype='multipart/form-data', PHP file handling functions (move_uploaded_file, $_FILES), or upload handlers/endpoints.
    Affected if The theme contains file upload functionality accessible to authenticated users
  4. Check upload directory configuration
    Locate the upload path configuration in the theme code and verify whether uploaded files are stored inside the webroot directory (publicly accessible).
    Affected if Uploaded files are stored within the webroot and can be accessed via URL
  5. Confirm script execution is enabled
    Verify that the upload directory does not have .htaccess rules or server configuration blocking PHP/script execution, and that uploaded files retain their original extensions.
    Affected if Uploaded files can retain executable extensions (such as .php) and are directly executable from the web directory

You are affected if the Miion theme version 1.2.7 or earlier is installed and includes file upload functionality that stores files within the webroot without disabling script execution.

Generated from the published advisory. Verify against your own configuration.
