{"id":"GHSA-xgpm-q3mq-46rq","summary":"PrestaShop some attribute not escaped in Validate::isCleanHTML method","details":"### Description\nSome event attributes are not detected by the isCleanHTML method\n\n### Impact\nSome modules using the isCleanHTML method could be vulnerable to xss\n\n### Patches\n8.1.3, 1.7.8.11\n\n### Workarounds\nThe 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`.\n\n### Reporters\n\nReported by Antonio Russo (@Antonio-R1 on GitHub) and Antonio Rocco Spataro (@antoniospataro on GitHub).\n\n","aliases":["CVE-2024-21627"],"modified":"2026-09-10T03:50:05.157935596Z","published":"2024-01-03T21:41:14Z","database_specific":{"nvd_published_at":"2024-01-02T21:15:10Z","cwe_ids":["CWE-20","CWE-79"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-01-03T21:41:14Z"},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/PrestaShop/PrestaShop/commit/0ed1af8de500538490f88e9e794e2e8113fb8df7"},{"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/commit/f799dcff564cd1b7ead932ffc3343b675107dbce"},{"type":"PACKAGE","url":"https://github.com/PrestaShop/PrestaShop"}],"affected":[{"package":{"name":"prestashop/prestashop","ecosystem":"Packagist","purl":"pkg:composer/prestashop/prestashop"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"8.0.0-beta.1"},{"fixed":"8.1.3"}]}],"versions":["8.0.0","8.0.0-beta.1","8.0.0-rc.1","8.0.1","8.0.2","8.0.3","8.0.4","8.0.5","8.1.0","8.1.0-beta.1","8.1.0-rc.1","8.1.1","8.1.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-xgpm-q3mq-46rq/GHSA-xgpm-q3mq-46rq.json"}},{"package":{"name":"prestashop/prestashop","ecosystem":"Packagist","purl":"pkg:composer/prestashop/prestashop"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.7.8.11"}]}],"versions":["1.7.0.0","1.7.0.0-beta.1.0","1.7.0.0-beta.2.0","1.7.0.0-beta.3.0","1.7.0.0-beta.4.0","1.7.0.0-rc.0.0","1.7.0.0-rc.1.0","1.7.0.0-rc.2.0","1.7.0.1","1.7.0.2","1.7.0.3","1.7.0.4","1.7.0.5","1.7.0.6","1.7.1.0","1.7.1.1","1.7.1.2","1.7.2.0","1.7.2.0-rc.1.0","1.7.2.1","1.7.2.2","1.7.2.3","1.7.2.4","1.7.2.5","1.7.3.0","1.7.3.1","1.7.3.2","1.7.3.3","1.7.3.4","1.7.4.0","1.7.4.0-beta.1","1.7.4.1","1.7.4.2","1.7.4.3","1.7.4.4","1.7.5.0","1.7.5.0-beta.1","1.7.5.0-rc.1","1.7.5.1","1.7.5.2","1.7.6.0","1.7.6.0-beta.1","1.7.6.0-rc.1","1.7.6.0-rc.2","1.7.6.1","1.7.6.2","1.7.6.3","1.7.6.4","1.7.6.5","1.7.6.6","1.7.6.7","1.7.6.8","1.7.6.9","1.7.7.0","1.7.7.0-beta.1","1.7.7.0-beta.2","1.7.7.0-rc.1","1.7.7.1","1.7.7.2","1.7.7.3","1.7.7.4","1.7.7.5","1.7.7.6","1.7.7.7","1.7.7.8","1.7.8.0","1.7.8.0-beta.1","1.7.8.0-rc.1","1.7.8.1","1.7.8.10","1.7.8.2","1.7.8.3","1.7.8.4","1.7.8.5","1.7.8.6","1.7.8.7","1.7.8.8","1.7.8.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-xgpm-q3mq-46rq/GHSA-xgpm-q3mq-46rq.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:N"}]}
