CVE-2026-46639

Twig is a template language for PHP. From 3.24.0 until 3.26.0, object-destructuring assignment compiles CoreExtension::getAttribute() with the sandbox argument hardcoded to false, disabling property and method policy checks and allowing an attacker with write access to a sandboxed Twig template to read public properties or invoke public getters on objects passed to the template engine. This issue is fixed in version 3.26.0.
