CVE-2021-47928Public exploitNetwork attack vector

Database disclosure via unneutralized product_id query

Published May 10, 2026 · Updated May 10, 2026

Blind SQL injection in OpenCart Multi-Vendor Multi-Seller Marketplace 3.0 allows remote attackers to read database data. The product/product route places product_id into a database predicate without neutralizing SQL syntax, so Boolean expressions alter returned content. No authentication is required; the published exploit uses response differences to enumerate usernames, email addresses, and reset codes.
