CVE-2026-93342

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.
