• Weakness: CWE-693

Description

Twig is a template language for PHP. Prior to 3.27.0, deprecated internal wrappers in src/Resources/core.php do not forward the current sandbox state to CoreExtension::checkArrow(), arraySome(), and arrayEvery(), allowing legacy calls such as twig_array_some(), twig_array_every(), and twig_check_arrow_in_sandbox() to bypass sandbox callable restrictions. This issue is fixed in version 3.27.0.

Affected products

• twigphp Twig: before 3.27.0 — fixed in 3.27.0

How to fix

Upgrade to a fixed version: twigphp Twig 3.27.0. Check the vendor advisory for mitigations.
