CyberRota Analysis
AI-GeneratedThe Fiber web framework, prior to versions 3.3.0 and 2.52.14, is vulnerable due to improper handling of the X-Real-IP header in the BalancerForward proxy helper, which allows an attacker to manipulate the IP address forwarded to upstream servers. This can lead to issues with logging, rate limiting, and access control, potentially compromising the integrity of these mechanisms. Organizations using affected versions of Fiber should prioritize updating to the patched versions to mitigate these risks.

Original NVD Description
Fiber is an Express inspired web framework written in Go. Prior to 3.3.0 and 2.52.14, the BalancerForward proxy helper in middleware/proxy/proxy.go uses Header.Add() instead of Header.Set() when injecting X-Real-IP, allowing an attacker-supplied first X-Real-IP value to be forwarded to upstream servers for logging, rate limiting, and access control. This issue is fixed in version 3.3.0 and 2.52.14.
