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 Themes4WP Bulk allows Accessing Functionality Not Properly Constrained by ACLs.This issue affects Bulk: from n/a through 1.0.11.

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

Missing authorization vulnerability in Themes4WP Bulk plugin (versions up to 1.0.11) allows attackers to access functionality that should be restricted by access control lists. This broken access control issue enables unauthorized users to perform actions they should not have permission to execute.

MitigationImplement proper authorization checks (nonce verification, capability checks, and user authentication validation) before executing any sensitive functionality in the Bulk plugin. Restrict all admin/functions to appropriate user roles.

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. Locate the Themes4WP Bulk plugin installation
    Check your WordPress wp-content/plugins directory for a folder named 'themes4wp-bulk' or similar. In the WordPress admin dashboard, go to Plugins > Installed Plugins and look for any plugin with 'Themes4WP' or 'Bulk' in the name.
    Affected if The plugin folder or listing is found in the WordPress installation
  2. Identify the installed plugin version
    If found in the plugins list, the version number is displayed in the plugin table. Alternatively, open the main plugin PHP file (usually in the plugin folder root) and check the plugin header comment for 'Version: x.x.x'
    Affected if The version displayed is 1.0.11 or lower
  3. Check for active user registration or subscriber accounts
    In WordPress admin, navigate to Users > All Users. Review the list for any registered users with roles other than Administrator, particularly Subscriber or Contributor roles, or check if User Registration is enabled on the site.
    Affected if Non-admin users exist on the site and the vulnerable plugin is installed
  4. Verify admin functionality access controls
    If you have access to the plugin source code, search the plugin files for action/filter hooks handling admin functions (like admin_init, wp_ajax_) and check if they include capability checks (current_user_can) or nonce verification before executing sensitive operations.
    Affected if The code lacks current_user_can() calls or wp_verify_nonce() checks before sensitive operations

A WordPress site is affected if the Themes4WP Bulk plugin is installed with version 1.0.11 or lower, regardless of whether non-admin users currently exist on the site.
