    Summary: on-headers is vulnerable to http response header manipulation

    Details: ### Impact A bug in on-headers versions `< 1.1.0` may result in response headers being inadvertently modified when an array is passed to `response.writeHead()` ### Patches Users should upgrade to `1.1.0` ### Workarounds Uses are encouraged to upgrade to `1.1.0`, but this issue can be worked around by passing an object to `response.writeHead()` rather than an array.
