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 MailerPress plugin is installed
    Log into the WordPress admin dashboard and navigate to Plugins > Installed Plugins. Look for 'MailerPress' in the list of active plugins.
    Affected if MailerPress appears in the installed plugins list
  2. Identify the installed MailerPress version
    In the WordPress admin, find the MailerPress plugin entry. The version number is displayed below the plugin name in the 'Version' column. Alternatively, inspect the main plugin file header via file manager or FTP to read the 'Version:' field in the plugin comment block.
    Affected if The version displayed is 2.0.2 or lower (e.g., 2.0.2, 2.0.1, 2.0.0, 1.x.x)
  3. Verify authenticated user access exists
    Review the WordPress Users menu to confirm there are user accounts with various roles (Subscriber, Contributor, Author, Editor, or custom roles) registered on the site.
    Affected if At least one authenticated user account exists on the WordPress site
  4. Check for unauthorized administrative access
    Test whether users with non-administrator roles (such as Subscriber or Contributor) can access WordPress admin pages, access /wp-admin/admin.php directly, or execute plugin functions that should be restricted to administrators. Inspect user role capabilities in Users > Roles or use a role inspector plugin to compare assigned capabilities against expected baseline capabilities for each role.
    Affected if Users with Subscriber, Contributor, or Author roles can access administrative functions, modify plugin settings, or execute actions reserved for Administrator role

A user is affected if MailerPress plugin version 2.0.2 or lower is installed and any non-administrator user account can access or modify administrative functions beyond their assigned role permissions.
