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 plugin versionCheck the installed plugin version via WordPress admin dashboard under Plugins > CouponXxL Custom Post Types, or inspect the main plugin file (usually couponxxl-cpt.php) in wp-content/plugins/ and look for the 'Version' header commentAffected if Version is 3.0 or lower (any version prior to 3.1)
-
Verify plugin is activeConfirm the plugin is enabled in WordPress admin under Plugins > Installed PluginsAffected if Plugin status shows as 'Active' - only active plugins can be exploited
-
Confirm user role configurationReview WordPress user roles under Users > Users in the admin panel to see if any low-privilege roles (Subscriber, Contributor, Author) exist on the siteAffected if Low-privilege authenticated users exist on the site - these are the accounts that could be exploited for privilege escalation
You are affected if the CouponXxL Custom Post Types plugin version is 3.0 or lower, the plugin is active, and low-privilege user accounts exist on the WordPress site.
