### Description

** DISPUTED ** Reflected Cross-site scripting (XSS) vulnerability in the web profiler in SensioLabs Symfony 3.3.6 allows remote attackers to inject arbitrary web script or HTML via the "file" parameter, aka an _profiler/open?file= URI.  NOTE: The vendor states "The XSS ... is in the web profiler, a tool that should never be deployed in production (so, we don't handle those issues as security issues)."
