NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-github-go-chi-chi package and not the golang-github-go-chi-chi package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

go-chi chi versions >= 5.2.1 and before 5.3.0 contain an IP spoofing vulnerability in the RealIP middleware, which blindly trusts the first (leftmost) value of the X-Forwarded-For HTTP header. A remote attacker can bypass IP-based access control lists and rate-limiting mechanisms, and forge log entries, by supplying a spoofed IP address in the X-Forwarded-For header. The issue is fixed in version 5.3.0.
