on-headers is a node.js middleware for listening to when a response writes headers. 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()
. Users should upgrade to version 1.1.0 to receive a patch. Uses are strongly 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.
