Linux Distros Unpatched Vulnerability : CVE-2026-118653

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

Origin Validation Error

Overview github.com/labstack/echo/v4/middleware is a middleware package for echo. Affected versions of this package are vulnerable to Origin Validation Error via the ToMiddleware function in the Echo proxy middleware. When EchoIPExtractor is unset, an attacker can bypass upstream IP-based access...

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-2026-118653 Echo: Rate Limiter Bypass via Spoofed X-Forwarded-For Header in Default Configuration

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...

CVE-2026-118651 Echo: Reverse Proxy Forwards Attacker-Supplied X-Real-IP to Upstream by Default

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-2026-118651

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...

LabStack Echo authorization issue vulnerability

In versions 4.0.0 through 5.1.0 of LabStack Echo, there is an authorization issue vulnerability. This occurs because when Echo.IPExtractor is not configured, Context.RealIP falls back to the X-Forwarded-For or X-Real-IP values provided by the client. By default, the RateLimiter uses these values ...

LabStack Echo input validation error vulnerability

In LabStack Echo versions 4.0.0 through 5.4.0, there is an input validation error vulnerability. This occurs because when Echo.IPExtractor is not configured, the Proxy middleware retains the X-Real-IP header provided by attackers and forwards it to upstream services. As a result, these services m...

CVE-2026-118653: Authentication Bypass by Spoofing

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.

GHSA-H53F-RM2W-W7RG Echo: X-Real-IP extractor trusts the header value instead of the sending peer

Impact In Echo v5, ExtractIPFromRealIPHeader checked whether the address supplied in X-Real-IP belonged to a trusted range instead of checking the address of the direct network peer. An untrusted client could therefore supply a loopback or private address and have it returned by c.RealIP with the...

CVE-2026-100390: Authentication Bypass by Spoofing

Zoraxy versions 3.2.3 through 3.3.4 fail to properly parse IPv6 addresses in the RemoteAddr field when setting forwarded headers. Unauthenticated attackers connecting over IPv6 can supply arbitrary X-Forwarded-For values to spoof their source IP and bypass authorization provider IP-based access...
