  "details": "Twig is affected by path traversal vulnerability when used with Twig_Loader_Filesystem for loading Twig templates but only if the application is using non-trusted template names (names provided by a end-user for instance).\n\nWhen affected, it is possible to go up one directory for the paths configured in the application\u0027s loader.\n\nFor instance, if the filesystem loader is configured with /path/to/templates as a path to look for templates, an attacker can force Twig to include a file stored in /path/to by prepending the path with /../ like in {% include \"/../somefile_in_path_to\" %}\n\nNote that using anything else (like ../somefile, /../../somefile, or ../../somefile) won\u2019t work and the application will return a proper exception.\n",
