CVE-2022-23614: Debian Linux

Critical severity, CVSS 9.8. EPSS: 8.2% chance of exploitation in the next 30 days.

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 Debian Linux: version 11.0 only
• Fedoraproject Fedora: version 34 only; version 35 only
• Symfony Twig: from 2.0.0, before 2.14.11 (fixed in 2.14.11); from 3.0.0, before 3.3.8 (fixed in 3.3.8)
