CVE-2022-23614: Code injection in Twig

• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 8.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2022-02-04 · updated 2026-06-17
• Weakness: CWE-74

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.

Affected products

• Debian Linux: 11.0
• Fedoraproject Fedora: 34, 35
• twigphp Twig: from 2.0.0 before 2.14.11; from 3.0.0 before 3.3.8 — fixed in 2.14.11, 3.3.8

How to fix

Upgrade to a fixed version: twigphp Twig 2.14.11, 3.3.8. Check the vendor advisory for mitigations.
