      "value": "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."

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."
