Summary
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.

Un error en las versiones de on-headers anteriores a la 1.1.0 puede provocar que los encabezados de respuesta se modifiquen accidentalmente al pasar una matriz a `response.writeHead()`. Los usuarios deben actualizar a la versi\u00f3n 1.1.0 para recibir una correcci\u00f3n. Se recomienda encarecidamente actualizar a la versi\u00f3n 1.1.0, pero este problema se puede solucionar pasando un objeto a `response.writeHead()` en lugar de una matriz."
