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
The LayoutBoxx plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 0.3.1. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

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 LayoutBoxx WordPress plugin (versions up to 0.3.1) contains an arbitrary shortcode execution vulnerability. The plugin fails to validate user input before passing it to WordPress's do_shortcode() function, allowing unauthenticated attackers to execute any registered shortcode on the site.

MitigationUpdate the LayoutBoxx plugin to a version beyond 0.3.1 once available, or deactivate and remove the plugin if no update exists, as unauthenticated arbitrary shortcode execution can lead to severe site compromise.

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 LayoutBoxx plugin is installed
    Navigate to WordPress admin > Plugins > Installed Plugins and look for 'LayoutBoxx' in the list, or check the /wp-content/plugins/ directory for a layoutboxx folder
    Affected if The LayoutBoxx plugin folder exists in the WordPress plugins directory
  2. Check installed version number
    In WordPress admin > Plugins, find LayoutBoxx and view the version number displayed below the plugin name, or read the main plugin PHP file header for the 'Version' field
    Affected if The installed version is 0.3.1 or lower (any version up to and including 0.3.1)
  3. Confirm plugin is active
    In WordPress admin > Plugins, verify that LayoutBoxx shows as 'Active' rather than 'Inactive' or 'Not Activated'
    Affected if The plugin is currently activated on the site

The site is affected if the LayoutBoxx plugin is installed, is version 0.3.1 or lower, and is currently active, as unauthenticated shortcode execution is possible.
