Description Guilherme de Almeida Suckevicz 2022-06-08 19:51:34 UTC 
Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on the origin server/application.
