    Medium [CVE-2026-72815] go-chi chi: IP spoofing via X-Forwarded-For header allows bypass of access controls

    CVE-2026-72815Source published Source updated

    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. When parsing incoming HTTP requests, the middleware blindly trusts the leftmost IP address in the X-Forwarded-For header without verifying proxy chain trust. Remote unauthenticated attackers can supply arbitrary client IP addresses to bypass IP-based access control lists (ACLs), evade rate-limiting rules, or forge audit trail logs, posing a Low impact to confidentiality and integrity.

    Mitigation guidance
    • Do not rely on the `RealIP` middleware when accepting connections from untrusted networks. Instead, configure an upstream reverse proxy (such as NGINX or HAProxy) to overwrite or sanitize client-supplied `X-Forwarded-For` headers before forwarding traffic to the application.
