{"id":"BIT-prestashop-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type will call `isCleanHTML`.","modified":"2026-07-16T09:11:45.299157675Z","published":"2024-03-06T11:02:28.587Z","withdrawn":"2026-07-16T09:00:05.298918637Z","database_specific":{"cpes":["cpe:2.3:a:prestashop:prestashop:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://github.com/PrestaShop/PrestaShop/commit/73cfb44666818eefd501b526a894fe884dd12129"},{"type":"WEB","url":"https://github.com/PrestaShop/PrestaShop/commit/ba06d18466df5b92cb841d504cc7210121104883"},{"type":"WEB","url":"https://github.com/PrestaShop/PrestaShop/security/advisories/GHSA-xgpm-q3mq-46rq"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-21627"}],"affected":[{"package":{"name":"prestashop","ecosystem":"Bitnami","purl":"pkg:bitnami/prestashop"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.0.0"},{"fixed":"8.1.3"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/prestashop/BIT-prestashop-2024-21627.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}],"schema_version":"1.7.3"}
