CVE-2023-30839Network attack vector

Database modification via development-only query rejection

Published Apr 25, 2023 · Updated Feb 3, 2025

SQL injection in PrestaShop before 1.7.8.9 and 8.0.0 through 8.0.3 allows remote authenticated users to alter database data via SQL Manager. Db::executeS checks for a read-only SQL verb but, outside developer mode, passed rejected statements to execute(), allowing SQL Manager filtering to reach write operations. Any back-office user who can submit a SQL Manager query can write, update, or delete database records without the corresponding database rights.
