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 checksWork through these to decide whether this CVE applies to you.
-
Locate the Themes4WP Bulk plugin installationCheck 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
-
Identify the installed plugin versionIf 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
-
Check for active user registration or subscriber accountsIn 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
-
Verify admin functionality access controlsIf 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement 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.
