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.

Summary		(es) Twig es un lenguaje de plantillas para PHP. Desde la versión 3.24.0 hasta la 3.26.0, la asignación de desestructuración de objetos compila CoreExtension::getAttribute() con el argumento sandbox codificado a false, deshabilitando las comprobaciones de políticas de propiedades y métodos y permitiendo a un atacante con acceso de escritura a una plantilla Twig en un sandbox leer propiedades públicas o invocar captadores públicos en objetos pasados al motor de plantillas. Este problema está solucionado en la versión 3.26.0.
