go-chi/chi versions 0.9.0 before 5.3.0 contains an IP spoofing vulnerability in the RealIP middleware, which resolves the request source IP Request.RemoteAddr using the first IP in the X-Forwarded-For header without validating trusted proxies. A malicious client can prepend a forged IP as the fir...

CVE-2026-72817

The CVE affects go-chi/chi up to version 0.9.0 before 5.3.0, where the RealIP middleware resolves the source IP (Request.RemoteAddr) from the first IP in X-Forwarded-For without validating trusted proxies. An attacker can insert a forged value as the first IP, enabling IP spoofing that may bypass...

CVE-2026-72815

The CVE-2026-72815 affects go-chi chi v5.2.1 up to, but not including, v5.3.0. The RealIP middleware blindly trusts the leftmost value of X-Forwarded-For, enabling an attacker to bypass IP-based ACLs and rate limits and forge log entries by spoofing the IP address. The issue is fixed in v5.3.0. R...

github.com/go-chi/chi/middleware: go-chi chi: IP spoofing via X-Forwarded-For header allows bypass of access controls

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...

github.com/go-chi/chi/middleware: go-chi/chi: IP spoofing via X-Forwarded-For header manipulation

A flaw was found in the go-chi/chi component. The RealIP middleware, responsible for resolving the request source IP, does not properly validate trusted proxies when processing the X-Forwarded-For header. A remote attacker can exploit this by prepending a forged IP address to the X-Forwarded-For...

CodeIgniter: Spoofable forwarded HTTPS headers in IncomingRequest::isSecure()

Impact IncomingRequest::isSecure trusted the X-Forwarded-Proto and Front-End-Https headers from any incoming request. In affected deployments, an attacker could spoof these headers and cause the application to incorrectly treat an HTTP request as secure. This may impact applications that rely on...
