{"id":"CVE-2024-21627","aliases":["GHSA-xgpm-q3mq-46rq"],"url":"https://o3.security/vulnerability/CVE-2024-21627","summary":"Some attribute not escaped in Validate::isCleanHTML method","details":"PrestaShop is an open-source e-commerce platform. Prior to versions 8.1.3 and 1.7.8.11, some event attributes are not detected by the `isCleanHTML` method. Some modules using the `isCleanHTML` method could be vulnerable to cross-site scripting. Versions 8.1.3 and 1.7.8.11 contain a patch for this issue. The best workaround is to use the `HTMLPurifier` library to sanitize html input coming from users. The library is already available as a dependency in the PrestaShop project. Beware though that in legacy object models, fields of `HTML` type will call `isCleanHTML`.","published":"2024-01-02T21:03:17.816Z","modified":"2026-08-08T03:48:01.417711935Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"prestashop/prestashop","fixedVersion":"8.1.3"},{"ecosystem":"Packagist","name":"prestashop/prestashop","fixedVersion":"1.7.8.11"}],"fix":{"url":"https://github.com/PrestaShop/PrestaShop/commit/73cfb44666818eefd501b526a894fe884dd12129","label":"PrestaShop/PrestaShop@73cfb44"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/21xxx/CVE-2024-21627.json"},{"type":"ADVISORY","url":"https://github.com/PrestaShop/PrestaShop/security/advisories/GHSA-xgpm-q3mq-46rq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-21627"},{"type":"FIX","url":"https://github.com/PrestaShop/PrestaShop/commit/73cfb44666818eefd501b526a894fe884dd12129"},{"type":"FIX","url":"https://github.com/PrestaShop/PrestaShop/commit/ba06d18466df5b92cb841d504cc7210121104883"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:48:01.417711935Z"}}
