Descriptions

The debug handler in Symfony before v2.7.33, 2.8.x before v2.8.26, 3.x before v3.2.13, and 3.3.x before v3.3.6 has XSS via an array key during exception pretty printing in ExceptionHandler.php, as demonstrated by a /_debugbar/open?op=get URI. NOTE: the vendor's position is that this is not a vulnerability because the debug tools are not intended for production use. NOTE: the Symfony Debug component is used by Laravel Debugbar

** EN DISPUTA ** El manipulador de depuración en Symfony, en versiones anteriores a la v2.7.33, versiones 2.8.x anteriores a la v2.8.26, versiones 3.x anteriores a la v3.2.13 y versiones 3.3.x anteriores a la v3.3.6, tiene Cross-Site Scripting (XSS) mediante una clave de array durante la impresión de excepciones pretty en ExceptionHandler.php, tal y como queda demostrado con un URI /_debugbar/open?op=get. NOTA: el fabricante sostiene que esta no es una vulnerabilidad debido a que las herramientas de depuración no están diseñadas para ser empleadas en producción. NOTA: el componente Symfony Debug es empleado por Laravel Debugbar.
