August 2023: Security hardening in PrestaShop/PrestaShop focused on preventing SQL injection via proper escaping of table identifiers. Implemented SQL table name escaping using bqSQL in the DB layer and DBQuery (commit 4d68f824619c0215f0224be33851fb4ade5ca61e). This targeted fix reduces the risk of injection in dynamically constructed queries and reinforces defense-in-depth without impacting existing features.
