{"id":"CVE-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":["BIT-prestashop-2023-30838","GHSA-fh7r-996q-gvcp"],"modified":"2026-05-19T03:51:39.551132646Z","published":"2023-04-25T18:22:54.521Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/30xxx/CVE-2023-30838.json","cwe_ids":["CWE-79"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/30xxx/CVE-2023-30838.json"},{"type":"ADVISORY","url":"https://github.com/PrestaShop/PrestaShop/security/advisories/GHSA-fh7r-996q-gvcp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-30838"},{"type":"FIX","url":"https://github.com/PrestaShop/PrestaShop/commit/46408ae4b02f3b8b1bb6e9dc63af5bcd858abd9c"},{"type":"FIX","url":"https://github.com/PrestaShop/PrestaShop/commit/dc682192df0e4b0d656a8e645b29ca1b9dbe3693"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/prestashop/prestashop","events":[{"introduced":"ca9d81aae0bb17f3e767bb5d835348ed144a3ab5"},{"fixed":"49d43b5fa0140304e64b530a5367cb30785eb15d"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-30838.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
