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

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

A missing authorization vulnerability in the edward_plainview MyCryptoCheckout WordPress plugin allows attackers to exploit incorrectly configured access control security levels. The plugin fails to properly validate user permissions before allowing access to certain functionality, potentially enabling unauthorized actions. This affects all versions up to and including 2.161.

MitigationImplement proper authorization checks and capability verification on all sensitive plugin functions and admin pages to ensure users have appropriate permissions before executing actions. Review and enforce correct access control security levels throughout the plugin.

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 MyCryptoCheckout plugin installation
    Check your WordPress plugins directory (typically wp-content/plugins/) for a folder named 'mycryptocheckout' or similar. Also check via WordPress admin under Plugins > Installed Plugins.
    Affected if The plugin folder exists on the server
  2. Determine installed plugin version
    Open the main plugin file (usually mycryptocheckout.php) and look for the 'Version' header comment at the top of the file, or check the plugin's readme.txt file.
    Affected if The version number found is below 2.162 (e.g., 2.161, 2.160, etc.)
  3. Verify vulnerable functionality is present
    Review the plugin files for admin action handlers or AJAX endpoints that perform sensitive operations. Look for functions that modify settings, process transactions, or access user data without checking current_user_can() or similar authorization checks.
    Affected if Sensitive functions lack proper capability checks or nonce verification before executing
  4. Check external exposure of admin interfaces
    If the plugin exposes REST API routes or AJAX handlers accessible via wp-admin/admin-ajax.php or wp-json/ without authentication requirements, test whether unauthenticated requests are accepted.
    Affected if Unauthenticated requests to plugin endpoints return successful responses instead of 401/403 errors

Your environment is affected if the MyCryptoCheckout plugin is installed with a version lower than 2.162 and the plugin exposes administrative functionality without proper authorization validation.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement proper authorization checks and capability verification on all sensitive plugin functions and admin pages to ensure users have appropriate permissions before executing actions. Review and enforce correct access control security levels throughout the plugin.

Recommended fix Moderate confidence

MyCryptoCheckout version > 2.161

  1. Log in to the WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Locate the MyCryptoCheckout plugin
  4. Check if an update is available and update to the latest version
  5. If no update is available through WordPress, download the latest version from the official WordPress plugin repository or contact the vendor directly
  6. After updating, verify the plugin is functioning correctly
  7. Review user roles and permissions to ensure only authorized users have access to administrative functions
