CVE-2026-16117 @fastify/http-proxy vulnerable to prefix escape via URL-encoded characters

Impact: @fastify/http-proxy versions up to and including 11.5.0 fail to rewrite the request prefix when the prefix segment is URL-encoded. Fastify's router URL-decodes paths for route matching, but request.url retains the original encoded form, and the prefix-rewrite step uses a literal string...

CVE-2026-16117

The CVE concerns @fastify/http-proxy (affected: up to 11.5.0) where URL prefix rewriting fails when the prefix segment is URL-encoded. Fastify decodes paths for route matching, but request.url keeps the original encoded form. The prefixRewrite step compares against the decoded prefix using a lite...

EUVD-2026-45375

Impact: @fastify/http-proxy versions from 9.4.0 up to and including 11.5.0 fail to validate the resolved WebSocket destination path against the configured rewrite prefix. The WebSocket routing path in WebSocketProxy.findUpstream resolves the destination via the WHATWG URL constructor, which...

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...

nginx: NGINX: Arbitrary code execution or Denial of Service via heap-based buffer overflow with crafted HTTP/2 headers

A flaw was found in NGINX. When NGINX is configured to proxy HTTP/2 traffic using the ngxhttpproxyv2module or ngxhttpgrpcmodule with specific settings, a remote, unauthenticated attacker can send specially crafted large headers. This can trigger a heap-based buffer overflow, leading to a restart ...

Name of the Vulnerable Software and Affected Versions Contour versions prior to 1.33.5 Description An issue exists when an HTTPProxy is configured with both .spec.virtualhost.tls.enableFallbackCertificate: true and .spec.virtualhost.jwtProviders. In this scenario, the system fails to reject the...

CVE-2026-55603

A flaw was found in http-proxy-middleware. A remote attacker could exploit a vulnerability in the fixRequestBody function, which is used to re-emit a request body. By injecting carriage return and line feed characters \r\n into a request body key or value, an attacker can bypass security policies...

CVE-2026-55602

A flaw was found in http-proxy-middleware before 2.0.10, 3.0.6, and 4.1.0. Router proxy-table host+path matching uses unanchored substring comparison on the Host header, so a crafted Host value that superstring-matches a configured key can route requests to an unintended backend...

CVE-2026-55603

http-proxy-middleware is node.js http-proxy middleware. From 3.0.4 until 3.0.7 and 4.1.1, fixRequestBody is the library's documented helper for re-emitting a request body that was already consumed by a body parser. When the outgoing Content-Type is multipart/form-data, it rebuilds the body with...

CVE-2026-55603

CVE-2026-55603 affects http-proxy-middleware (Node.js). In versions 3.0.4–3.0.7 and 4.1.1, fixRequestBody() rebuilds multipart/form-data by interpolating req.body into the wire format without neutralizing CR/LF. This can let an attacker inject a new multipart part (via unescaped CRLF in keys/valu...
