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 Mad Fish Digital Bulk NoIndex & NoFollow Toolkit allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Bulk NoIndex & NoFollow Toolkit: from n/a through 1.5.

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 the Bulk NoIndex & NoFollow Toolkit WordPress plugin allows authenticated users (including low-privilege users like subscribers) to perform actions that should be restricted to administrators. This is a classic Broken Access Control (BAC) vulnerability where the plugin fails to verify user capabilities before executing sensitive operations.

MitigationImplement proper capability checks (current_user_can) and nonce verification on all AJAX actions and admin functions. Update to the latest patched version when released. In the interim, restrict plugin access to administrator-level users only via WordPress role management.

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. Confirm plugin installation
    Navigate to WordPress admin > Plugins and check if 'Bulk NoIndex & NoFollow Toolkit' is installed and activated
    Affected if Plugin is present and active in the WordPress installation
  2. Identify installed version
    In Plugins list, locate the plugin and note the version number displayed, or check the plugin's main PHP file header for the Version tag
    Affected if Version is unknown, unpatched, or falls within any known vulnerable range
  3. Verify AJAX action accessibility
    Use browser developer tools or curl to test whether AJAX endpoints (typically under wp-admin/admin-ajax.php) exposed by this plugin respond to requests from low-privilege authenticated users (subscriber role)
    Affected if AJAX actions return successful responses for subscriber-level users without returning a capability error
  4. Inspect capability verification in plugin code
    Access the plugin files via FTP or file manager, then examine the main plugin PHP file and any AJAX handler files for presence of current_user_can checks before sensitive operations
    Affected if No current_user_can or capability checks are found before executing administrative functions

If the plugin is installed and low-privilege users (subscriber role) can access admin-level functions without capability verification, the environment is affected by this authorization bypass.
