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...

The CVE-2026-55602 issue affects http-proxy-middleware (Node.js) versions 0.16.0 through 2.0.10, 3.0.6, and 4.1.0. The host+path router uses unanchored substring matching on attacker-controlled request metadata, enabling a crafted Host header that is a superstring match for a configured key to ro...
CRLF Injection
Overview Affected versions of this package are vulnerable to CRLF Injection via the fixRequestBody function. An attacker can inject or override multipart form fields, potentially bypassing gateway-side validation or access controls, by supplying crafted input containing carriage return and line...
