Name of the Vulnerable Software and Affected Versions
go-chi chi versions 5.2.1 through 5.2.9
Description
The RealIP middleware blindly trusts the first (leftmost) value of the
X-Forwarded-For HTTP header. This allows a remote attacker to supply a spoofed IP address in the X-Forwarded-For header to bypass rate-limiting mechanisms and IP-based access control lists, as well as to forge log entries.Recommendations
Update go-chi chi to version 5.3.0.
