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."}], "lastModified": "2023-05-09T19:46:44.303", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:prestashop:prestashop:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "38174A16-34A0-4E08-8485-B413ADC32907", "versionEndExcluding": "1.7.8.9"}, {"criteria": "cpe:2.3:a:prestashop:prestashop:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B84AB40A-755F-4AD7-AD86-D2FD642C710D", "versionEndExcluding": "8.0.4", "versionStartIncluding": "8.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
