GHSA-XR57-GCX8-52HF AsyncHttpClient sends origin credentials to the proxy on the plaintext CONNECT request

Impact When a request uses an HTTP proxy to reach an HTTPS origin, the client opens the tunnel with a plaintext CONNECT sent to the proxy before any TLS exists. On affected versions the origin's preemptive credentials were added to that CONNECT. A Basic realm sent Authorization: Basic...

DEBIAN-CVE-2026-85720

The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.0.0 until 2.16.1 and 3.0.12, a request using an HTTP proxy to reach an HTTPS origin can expose preemptive origin credentials because NettyRequestFactory and...

CVE-2026-91143 goproxy through 15.3 Authentication Bypass via CONNECT

goproxy through 15.3 fails to apply HTTP proxy basic authentication to CONNECT tunnel requests, allowing unauthenticated clients to bypass credential requirements. Attackers can issue CONNECT requests to establish tunnels through the authenticated proxy without providing credentials, enabling...

netty: io.netty/netty-handler-proxy: Netty: HTTP Header Injection via HttpProxyHandler Disabled Validation

A flaw was found in Netty. The HttpProxyHandler component, which handles HTTP CONNECT requests, does not properly validate user-provided outbound headers. This allows an attacker to inject arbitrary HTTP headers into the CONNECT request sent to the proxy server. This could lead to unexpected...

GHSA-9468-V6MJ-FPPW Centrifugo: Client-forgeable headers emulation lets any client spoof headers forwarded to proxy backends

Vulnerability Details File: internal/client/handler.go OnClientConnecting, internal/proxy/http.go requestHeaders, internal/proxy/grpc.go requestMetadata, internal/unigrpc/grpc.go Consume Line: handler.go:389,548-552 e.Headers - SetEmulatedHeadersToContext, http.go:131-165 requestHeaders,...

Astra Linux – Vulnerability in curl

curl will incorrectly reuse an existing HTTP proxy connection when making a CONNECT request to a server, even if the new request uses different credentials for the HTTP proxy. The correct behavior is to create or use a separate connection...

CVE-2026-71485

Centrifugo (open-source real-time messaging server) prior to 6.9.0 contains a header spoofing vulnerability in its proxy and transport layers. The client-controlled protocol.ConnectRequest.headers map is copied through OnClientConnecting, ConnectEvent.Headers, and SetEmulatedHeadersToContext, and...

curl: curl: Unauthorized access due to improper HTTP proxy connection reuse

A flaw was found in curl. This vulnerability allows curl to wrongly reuse an existing HTTP proxy connection when performing a CONNECT request to a server, even if the new request uses different authentication credentials for the HTTP proxy. This improper connection reuse could lead to an attacker...
