SQL Injection in Premium Packages – Sell Digital Products Securely (WordPress plugin) (CVE-2026-12800)
Summary
SQL injection in Premium Packages – Sell Digital Products Securely (WordPress plugin) (CVE-2026-12800). Confidential information can be exposed externally. Exploitable via POST /wp-json/wpdmpp/v1/cart/coupon.
Original description
The description as published by the source.
The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to SQL Injection via the 'code' parameter of the POST /wp-json/wpdmpp/v1/cart/coupon REST API endpoint in versions up to, and including, 6.2.0. This is due to insufficient escaping on the user-supplied parameter, which is interpolated directly into a raw SQL query string in the CouponCodes::find() method without use of $wpdb->prepare() or esc_sql(). This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
