{"id":"BIT-prestashop-2023-30838","summary":"PrestaShop vulnerable to possible XSS injection through Validate::isCleanHTML method","details":"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.","aliases":["CVE-2023-30838","GHSA-fh7r-996q-gvcp"],"modified":"2025-05-20T10:02:07.006Z","published":"2024-03-06T11:04:42.793Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:prestashop:prestashop:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://github.com/PrestaShop/PrestaShop/commit/46408ae4b02f3b8b1bb6e9dc63af5bcd858abd9c"},{"type":"WEB","url":"https://github.com/PrestaShop/PrestaShop/commit/dc682192df0e4b0d656a8e645b29ca1b9dbe3693"},{"type":"WEB","url":"https://github.com/PrestaShop/PrestaShop/security/advisories/GHSA-fh7r-996q-gvcp"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-30838"}],"affected":[{"package":{"name":"prestashop","ecosystem":"Bitnami","purl":"pkg:bitnami/prestashop"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.0.0"},{"fixed":"8.0.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/prestashop/BIT-prestashop-2023-30838.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}],"schema_version":"1.7.3"}
