CVE-2026-118651

Echo is a Go web framework. From 4.0.0 until 5.4.0, the Proxy middleware can preserve an attacker-supplied X-Real-IP header and forward it to an upstream service when Echo.IPExtractor is not configured. A remote client can therefore make upstream services receive a spoofed client address,...

CVE-2026-118653

Echo is a Go web framework. From 4.0.0 until 5.1.0, Context.RealIP falls back to client-supplied X-Forwarded-For or X-Real-IP values when Echo.IPExtractor is unset, and the default RateLimiter uses that result as its client identifier. A remote attacker can rotate arbitrary forwarded-address valu...

GHSA-99JH-6H7P-PP36 Echo: Reverse Proxy Forwards Attacker-Supplied X-Real-IP to Upstream by Default

Summary The Echo proxy middleware middleware/proxy.go preserves an incoming X-Real-IP header verbatim and forwards it to the upstream service when EchoIPExtractor is not configured — which is the default. Because any HTTP client can supply an arbitrary X-Real-IP value, an attacker can cause Echo ...

CVE-2026-118651

The Echo Go web framework (versions 4.0.0 through 5.4.0 ) contains a vulnerability where the Proxy middleware forwards an attacker-supplied X-Real-IP header to upstream services by default. This occurs when Echo.IPExtractor is not configured, allowing a remote client to spoof their client address...

CVE-2026-118265

Echo is a Go web framework. From 5.0.0 until 5.4.1, Echo v5's ExtractIPFromRealIPHeader validates whether the client-supplied X-Real-IP value belongs to a trusted range instead of validating the direct network peer. A client reaching Echo directly, or through a proxy that preserves the header, ca...

CVE-2026-118265

The Echo Go web framework (versions v5.0.0 through v5.4.0 ) contains a vulnerability in the ExtractIPFromRealIPHeader component. The root cause is that the framework validates whether the X-Real-IP header value belongs to a trusted range rather than verifying the direct network peer. This allows ...
