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
Missing Authorization vulnerability in WebToffee WordPress Backup & Migration wp-migration-duplicator allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects WordPress Backup & Migration: from n/a through <= 1.4.1.

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

The WebToffee WordPress Backup & Migration plugin (wp-migration-duplicator) contains a missing authorization vulnerability where the plugin fails to properly enforce access control checks, allowing authenticated users (possibly with low privileges) to perform actions that should require higher-level permissions or administrative rights.

MitigationUpdate the plugin to the latest version once available, or implement proper capability checks and nonce verification on all sensitive functions. Until patched, restrict access to affected endpoints at the server level.

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 the plugin is installed
    Navigate to WordPress Admin > Plugins and look for 'WebToffee WordPress Backup & Migration' or 'wp-migration-duplicator' in the installed plugins list. Check if the plugin is activated.
    Affected if the plugin is installed and activated on the WordPress site
  2. Identify the installed plugin version
    In the Plugins list, click on the plugin name or view the plugin files to locate the version number in the plugin header comment (typically in the main PHP file). Compare this version to the patched version released by the vendor.
    Affected if the installed version is older than the patched version (contact vendor for specific version numbers)
  3. Review user roles with administrative access
    Go to WordPress Admin > Users and list all users with Administrator role. Verify that only trusted users have admin access.
    Affected if untrusted or unknown users have Administrator role access
  4. Check for low-privilege users with plugin access
    Review all user roles (Editor, Author, Contributor, Subscriber) and test whether they can access the plugin menu items or trigger plugin actions by navigating to the plugin's admin pages or using its AJAX endpoints.
    Affected if users with roles below Administrator can access plugin functions or endpoints

The environment is affected if the WebToffee WordPress Backup & Migration plugin is installed, the installed version predates the vendor patch, and users with roles below Administrator can access the plugin's sensitive functions or endpoints.
