Affected packages

• Packagist prestashop/prestashop: >= 8.0.0, < 8.0.4 → fixed in 8.0.4 • Packagist prestashop/prestashop: < 1.7.8.9 → fixed in 1.7.8.9

Description

Impact ValidateCore::isCleanHTML() method of Prestashop misses hijickable events which can lead to XSS injection, allowed by the presence of pre-setup @keyframes methods. This XSS which hijacks HTML attributes will be triggered without any interaction of the visitor/administrator which makes it as dangerous as a trivial XSS. Contrary to most XSS which target HTML attributes and which 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. Patches The patch will be on PS 8.0.4 and PS 1.7.8.9 References
