In PrestaShop before 1.7.6.0 RC2, the idaddressdelivery and idaddressinvoice parameters are affected by an Insecure Direct Object Reference vulnerability due to a guessable value sent to the web application during checkout. An attacker could leak personal customer information. This is PrestaShop bug #14444.

In PrestaShop 1.7.5.2, the shopcountry parameter in the install/index.php installation script/component is affected by Reflected XSS. Exploitation by a malicious actor requires the user to follow the initial stages of the setup (accepting terms and conditions) before executing the malicious link.
