CVSS 6.5 MEDIUM
A flaw was found in the `go-chi chi` RealIP middleware. This vulnerability allows a remote attacker to spoof their IP address by manipulating the `X-Forwarded-For` HTTP header. By exploiting this, an attacker can bypass IP-based access control lists and rate-limiting mechanisms, and forge log entries, potentially leading to unauthorized access or misattribution of actions.
