Summary
Koa is expressive middleware for Node.js using ES2017 async functions. Prior to versions 0.21.2, 1.7.1, 2.15.4, and 3.0.0-alpha.3, Koa uses an evil regex to parse the `X-Forwarded-Proto` and `X-Forwarded-Host` HTTP headers. This can be exploited to carry out a Denial-of-Service attack. Versions 0.21.2, 1.7.1, 2.15.4, and 3.0.0-alpha.3 fix the issue.

En versiones anteriores a las 0.21.2, 1.7.1, 2.15.4 y 3.0.0-alpha.3, Koa utiliza una expresi\u00f3n regular maliciosa para analizar los encabezados HTTP `X-Forwarded-Proto` y `X-Forwarded-Host`. Esto se puede aprovechar para llevar a cabo un ataque de denegaci\u00f3n de servicio. Las versiones 0.21.2, 1.7.1, 2.15.4 y 3.0.0-alpha.3 solucionan el problema."
