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 installed plugin versionNavigate to WordPress Admin > Plugins > Installed Plugins, find 'Checkout Mestres WP', and note the version number displayed. Alternatively, check the plugin's main PHP file in wp-content/plugins/checkout-mestres-wp/ for the 'Version' header in the plugin comments.Affected if Version is 7.1.9.7 or any earlier version
-
Compare your version to the affected rangeReview the version identified in step 1. The vulnerability affects all versions through 7.1.9.7, meaning versions 7.1.9.7 and below are vulnerable.Affected if Installed version is 7.1.9.7 or lower
-
Identify the plugin's authentication endpointsInspect the plugin files in wp-content/plugins/checkout-mestres-wp/ for PHP files handling login, authentication, or user registration (commonly named like login.php, auth.php, or containing 'init', 'wp_ajax', or 'rest_api_init' hooks). Note the URLs and parameters these files expose.Affected if The plugin exposes authentication-related endpoints and the installed version is 7.1.9.7 or lower
-
Review WordPress user accounts for unauthorized administratorsGo to WordPress Admin > Users and examine the list of users with Administrator role. Look for unfamiliar accounts, recently added accounts, or accounts with usernames or email addresses you do not recognize.Affected if Any unknown administrator accounts exist, suggesting exploitation has occurred
-
Check for recent user creation activityReview the user table in the WordPress database (wp_users and wp_usermeta) or the activity logs for user accounts created within a timeframe matching the plugin's active period, particularly with the administrator capability (wp_capabilities meta value containing 'administrator').Affected if Administrator accounts were created without your knowledge
Your environment is affected if the installed Checkout Mestres WP plugin version is 7.1.9.7 or lower, and the plugin's authentication functionality is active on the site.
