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 Plus Addons for Elementor plugin for WordPress is vulnerable to arbitrary file reads in versions up to, and including 4.1.9 (pro) and 2.0.6 (free). The plugin has a feature to add an "Info Box" to an Elementor created page. This Info Box can include an SVG image for the box. Unfortunately, the plugin used file_get_contents with no verification that the file being supplied was an SVG file, so any user with access to the Elementor page builder, such as contributors, could read arbitrary files on the WordPress installation.

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 Plus Addons for Elementor plugin has an arbitrary file read vulnerability in its Info Box feature. The plugin uses file_get_contents() to load SVG images without validating that the requested file is actually an SVG, allowing authenticated users with Elementor page builder access (contributors and above) to read any accessible file on the server.

MitigationUpgrade to version 4.1.10 (pro) or 2.0.7 (free) which adds proper file type validation, or restrict Elementor builder access to trusted users only until the patch can be applied.

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 plugin installation and version
    In WordPress admin, go to Plugins > Installed Plugins. Look for 'The Plus Addons For Elementor' (free) or 'The Plus Addons For Elementor Pro'. Note the installed version number shown.
    Affected if The plugin is installed and version is 2.0.6 or lower for free, or 4.1.9 or lower for pro.
  2. Determine if Elementor builder access is open to low-privileged users
    Go to Users > All Users in WordPress admin. Check which users have access to the Elementor page editor. Typically, Contributor role and above can access Elementor if enabled in User Roles settings under The Plus Addons settings.
    Affected if Users with Contributor, Author, or Editor roles have permission to use Elementor page builder.
  3. Identify if Info Box widget is in use
    Search your WordPress content for pages or posts edited with Elementor that include the Info Box widget. In Elementor editor, search 'Info Box' in the widget panel. Check existing pages by viewing source for elements containing 'theplus-info-box' or similar class names.
    Affected if Any page or post uses the Info Box widget from this plugin.
  4. Verify the vulnerable file read endpoint exists
    Attempt to access a known vulnerable endpoint pattern such as /wp-admin/admin-ajax.php?action=theplus_get_post_by_id&post_id=../../wp-config. If the response contains file contents or displays an error related to file access, the endpoint is reachable.
    Affected if The endpoint responds and allows reading files outside the intended SVG directory.

A user is affected if the Plus Addons for Elementor plugin is installed at version 2.0.6 or below (free) or 4.1.9 or below (pro), and the Info Box widget is accessible to users with Contributor-level access or higher.

Upgrade available Upgrade to a release after 4.1.9
Interim mitigation

Upgrade to version 4.1.10 (pro) or 2.0.7 (free) which adds proper file type validation, or restrict Elementor builder access to trusted users only until the patch can be applied.

Recommended fix Moderate confidence

Free: > 2.0.6; Pro: > 4.1.9 (upgrade to latest available version from WordPress plugin repository or vendor)

  1. 1. Update The Plus Addons For Elementor (free version) to the latest available version from the WordPress plugin repository
