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.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2023-04-25 19:15:00","updated_at":"2023-05-09 19:46:00"},"problem_types":["CWE-79"],"metrics":[],"references":[{"url":"https://github.com/PrestaShop/PrestaShop/commit/46408ae4b02f3b8b1bb6e9dc63af5bcd858abd9c","name":"https://github.com/PrestaShop/PrestaShop/commit/46408ae4b02f3b8b1bb6e9dc63af5bcd858abd9c","refsource":"MISC","tags":[],"title":"Merge pull request from GHSA-fh7r-996q-gvcp · PrestaShop/PrestaShop@46408ae · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/PrestaShop/PrestaShop/commit/dc682192df0e4b0d656a8e645b29ca1b9dbe3693","name":"https://github.com/PrestaShop/PrestaShop/commit/dc682192df0e4b0d656a8e645b29ca1b9dbe3693","refsource":"MISC","tags":[],"title":"Merge pull request from GHSA-fh7r-996q-gvcp · PrestaShop/PrestaShop@dc68219 · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/PrestaShop/PrestaShop/security/advisories/GHSA-fh7r-996q-gvcp","name":"https://github.com/PrestaShop/PrestaShop/security/advisories/GHSA-fh7r-996q-gvcp","refsource":"MISC","tags":[],"title":"Possible XSS injection through Validate::isCleanHTML method · Advisory · PrestaShop/PrestaShop · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-30838","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-30838","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"30838","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"prestashop","cpe5":"prestashop","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2023-30838","ASSIGNER":"security-advisories@github.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"PrestaShop is an Open Source e-commerce web application.
