CVE-2026-46633

Twig is a template language for PHP. Prior to 3.26.0, Compiler::string() does not escape single quotes when a template name from a {% use %} tag is placed inside a PHP single-quoted string literal, allowing a crafted template name to terminate the string and inject arbitrary PHP expressions into the compiled cache file. This issue is fixed in version 3.26.0.

Summary		(es) Twig es un lenguaje de plantillas para PHP. Antes de la versión 3.26.0, Compiler::string() no escapa las comillas simples cuando un nombre de plantilla de una etiqueta {% use %} se coloca dentro de un literal de cadena de PHP entre comillas simples, lo que permite que un nombre de plantilla manipulado termine la cadena e inyecte expresiones PHP arbitrarias en el archivo de caché compilado. Este problema está corregido en la versión 3.26.0.
