PrestaShop is an Open Source e-commerce web application. Prior to versions 8.0.4 and 1.7.8.9, the ValidateCore::isCleanHTML() method of Prestashop misses hijackable events which can lead to cross-site scripting (XSS) injection, allowed by the presence of pre-setup @keyframes methods. This XSS, which hijacks HTML attributes, can be triggered without any interaction by the visitor/administrator, which makes it as dangerous as a trivial XSS attack. Contrary to other attacks which target HTML attributes and are triggered without user interaction (such as onload / onerror which suffer from a very limited scope), this one can hijack every HTML element, which increases the danger due to a complete HTML elements scope. Versions 8.0.4 and 1.7.8.9 contain a fix for this issue.

PrestaShop is an Open Source e-commerce web application. Versions prior to 8.0.4 and 1.7.8.9 contain a SQL filtering vulnerability. A BO user can write, update, and delete in the database, even without having specific rights. PrestaShop 8.0.4 and 1.7.8.9 contain a patch for this issue. There are no known workarounds.

PrestaShop is an Open Source e-commerce web application. Prior to versions 8.0.4 and 1.7.8.9, it is possible for a user with access to the SQL Manager (Advanced Options -> Database) to arbitrarily read any file on the operating system when using SQL function LOADFILE in a SELECT request. This gives the user access to critical information. A patch is available in PrestaShop 8.0.4 and PS 1.7.8.9
