Subject: CVE-2022-31813: Apache HTTP Server: mod_proxy X-Forwarded-For
 dropped by hop-by-hop mechanism 

Severity: low


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.


The Apache HTTP Server project would like to thank Gaetan Ferry (Synacktiv) for reporting this issue
