CVE-2026-94080

The MarketKing plugin for WordPress versions 2.1.40 and earlier contains a broken access control vulnerability exploitable by an unauthenticated attacker.

MarketKing plugin for WordPress before 2.1.72 contains a missing authorization vulnerability in the marketking_get_page_content AJAX action that allows authenticated attackers with subscriber-level access or higher to access arbitrary vendor administrator panel pages by supplying an arbitrary vendor user ID. Attackers can bypass authorization controls by submitting a target vendor ID in the request to access payout pages, financial reports, and vendor dashboard content belonging to any vendor in the marketplace.

The MarketKing plugin for WordPress before 2.1.72 contains a missing authorization vulnerability in the marketking_admin_vendors_ajax AJAX action that allows authenticated attackers with subscriber-level access or higher to retrieve the complete vendor directory. By sending a crafted AJAX request, they can obtain internal user IDs, usernames, and email addresses of all registered vendors, exposing personally identifiable information.

The MarketKing plugin for WordPress before 2.1.72 contains a missing authorization vulnerability in the marketking_duplicate_product AJAX action that allows authenticated attackers with subscriber-level access or higher to duplicate any vendor's product by supplying an arbitrary product ID. Attackers can bypass ownership verification, copy any vendor's product listings including private metadata, and assign the duplicate to their own account without the victim's consent.

The MarketKing plugin for WordPress before 2.1.72 contains a missing authorization vulnerability in the marketking_send_refund AJAX action that allows authenticated attackers with subscriber-level access or higher to create refund requests against any order by supplying an arbitrary order ID. Attackers can submit crafted AJAX requests to create fraudulent refund requests against orders they did not place, causing marketplace disruption and unauthorized interference.

Missing Authorization vulnerability in MarketKing by Kings Plugins allows exploiting incorrectly configured access control security levels. Affects versions through 2.1.60.
