{"id":"CVE-2022-29221","aliases":["GHSA-634x-pc3q-cf4c"],"url":"https://o3.security/vulnerability/CVE-2022-29221","summary":"PHP Code Injection by malicious block or filename in Smarty","details":"Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. Prior to versions 3.1.45 and 4.1.1, template authors could inject php code by choosing a malicious {block} name or {include} file name. Sites that cannot fully trust template authors should upgrade to versions 3.1.45 or 4.1.1 to receive a patch for this issue. There are currently no known workarounds.","published":"2022-05-24T00:00:00Z","modified":"2026-07-15T01:49:09.243820342Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":2,"affectedPackages":[{"ecosystem":"Packagist","name":"smarty/smarty","fixedVersion":"3.1.45"},{"ecosystem":"Packagist","name":"smarty/smarty","fixedVersion":"4.1.1"}],"fix":{"url":"https://github.com/smarty-php/smarty/commit/64ad6442ca1da31cefdab5c9874262b702cccddd","label":"smarty-php/smarty@64ad644"},"references":[{"type":"WEB","url":"https://github.com/smarty-php/smarty/releases/tag/v3.1.45"},{"type":"WEB","url":"https://github.com/smarty-php/smarty/releases/tag/v4.1.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/29xxx/CVE-2022-29221.json"},{"type":"ADVISORY","url":"https://github.com/smarty-php/smarty/security/advisories/GHSA-634x-pc3q-cf4c"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BRAJVDRGCIY5UZ2PQHKDTT7RMKG6WJQQ/"},{"type":"ADVISORY","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L777JIBIWJV34HS7LXPIDWASG7TT4LNI/"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-29221"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202209-09"},{"type":"ADVISORY","url":"https://www.debian.org/security/2022/dsa-5151"},{"type":"FIX","url":"https://github.com/smarty-php/smarty/commit/64ad6442ca1da31cefdab5c9874262b702cccddd"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2022/05/msg00044.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:09.243820342Z"}}
