Summary
PrestaShop before 8.2.9 and 9.2.1 contains a broken access control vulnerability that allows an authenticated Webservice API key holder to read and modify customer records belonging to any shop in a multi-shop installation. Attackers can exploit the missing record-level shop ownership check in shopHasRight() and saveEntityFromXml() to read sensitive customer data such as password hashes and secure keys, and change a customer's email and password via create, update, and delete requests, resulting in account takeover.
