  "description": "on-headers is a node.js middleware for listening to when a response writes headers. A bug in on-headers versions \u0060\u003C1.1.0\u0060 may result in response headers being inadvertently modified when an array is passed to \u0060response.writeHead()\u0060.\u00A0Users should upgrade to version 1.1.0 to receive a patch.\u00A0Uses are strongly encouraged to upgrade to \u00601.1.0\u0060, but this issue can be worked around by passing an object to \u0060response.writeHead()\u0060 rather than an array.",
