{"id":"CVE-2021-29454","details":"Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. Prior to versions 3.1.42 and 4.0.2, template authors could run arbitrary PHP code by crafting a malicious math string. If a math string was passed through as user provided data to the math function, external users could run arbitrary PHP code by crafting a malicious math string. Users should upgrade to version 3.1.42 or 4.0.2 to receive a patch.","aliases":["GHSA-29gp-2c3m-3j6m"],"modified":"2026-05-18T05:54:57.884147794Z","published":"2022-01-10T20:15:08Z","database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:11.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD","vendor_product":"debian:debian_linux","extracted_events":[{"last_affected":"9.0"},{"last_affected":"10.0"},{"last_affected":"11.0"}]},{"cpes":["cpe:2.3:o:fedoraproject:fedora:36:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:37:*:*:*:*:*:*:*"],"source":"CPE_FIELD","vendor_product":"fedoraproject:fedora","extracted_events":[{"last_affected":"36"},{"last_affected":"37"}]}]},"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BRAJVDRGCIY5UZ2PQHKDTT7RMKG6WJQQ/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L777JIBIWJV34HS7LXPIDWASG7TT4LNI/"},{"type":"ADVISORY","url":"https://github.com/smarty-php/smarty/releases/tag/v3.1.42"},{"type":"ADVISORY","url":"https://github.com/smarty-php/smarty/releases/tag/v4.0.2"},{"type":"ADVISORY","url":"https://github.com/smarty-php/smarty/security/advisories/GHSA-29gp-2c3m-3j6m"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2022/05/msg00005.html"},{"type":"ADVISORY","url":"https://packagist.org/packages/smarty/smarty"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202209-09"},{"type":"ADVISORY","url":"https://www.debian.org/security/2022/dsa-5151"},{"type":"ADVISORY","url":"https://www.smarty.net/docs/en/language.function.math.tpl"},{"type":"FIX","url":"https://github.com/smarty-php/smarty/commit/215d81a9fa3cd63d82fb3ab56ecaf97cf1e7db71"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/smarty-php/smarty","events":[{"introduced":"0"},{"fixed":"b674cba13d4ae61f063aec20f84a3ec40c006124"},{"introduced":"baebd59bb4da9fca89da382811b38c8313949c49"},{"fixed":"6f4f06db7ebbad6ae7bc98027d9385e60a016906"},{"fixed":"215d81a9fa3cd63d82fb3ab56ecaf97cf1e7db71"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.1.42"},{"introduced":"4.0.0"},{"fixed":"4.0.2"}],"source":["CPE_FIELD","REFERENCES"],"cpe":"cpe:2.3:a:smarty:smarty:*:*:*:*:*:*:*:*"}}],"versions":["v3.1.41","v4.0.1","v4.0.0","v3.1.40","v3.1.39","v3.1.38","v3.1.37.1","v3.1.37","v3.1.36","v3.1.35","v3.1.34","v3.1.33","v3.1.32","v3.1.31","v3.1.30","v3.1.29","v3.1.28","v2.6.28","v3.1.27","v3.1.26","v3.1.25","v3.1.24","v3.1.23","v3.1.21","v3.1.20","v3.1.19","v3.1.18","v3.1.17","v3.1.16","v3.1.15","v3.1.14","v3.1.13","v3.1.12","v3.1.11","v2.6.27","v2.6.26","v2.6.25","v2.6.24"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-29454.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
