High · 8.8 Public exploit CVE-2022-23614 EUVD-2022-0842GHSA-5mv2-rx3q-4w2v

Code injection in Twig

Published Feb 4, 2022 · Updated Apr 23, 2025 · Assigned by GitHub_M

Vendor: twigphp Product: Twig Package: php-twig Package: php-twig Package: twig/twig Ecosystem: Debian Ecosystem: Packagist Ecosystem: Ubuntu

Description

Twig is an open source template language for PHP. When in a sandbox mode, the `arrow` parameter of the `sort` filter must be a closure to avoid attackers being able to run arbitrary PHP functions. In affected versions this constraint was not properly enforced and could lead to code injection of arbitrary PHP code. Patched versions now disallow calling non Closure in the `sort` filter as is the case for some other filters. Users are advised to upgrade.
