CVE-2026-46639 (opens in a new tab)How to fix?
Upgrade twig/twig to version 3.26.0 or higher.
Overview
twig/twig is a flexible, fast, and secure template language for PHP.
Affected versions of this package are vulnerable to Incorrect Authorization via object-destructuring assignment handling in ObjectDestructuringSetBinary::compile(). An attacker can bypass Twig sandbox property and method restrictions because destructuring expressions invoke CoreExtension::getAttribute() with the $sandboxed argument hardcoded to false, disabling SecurityPolicy enforcement for attribute access. This allows access to arbitrary public properties and getters on objects exposed to sandboxed templates.
