nghttp2's nghttpx proxy through 1.69.0 forwards an HTTP/1.1 Upgrade request that also carries a Content-Length header and body onto reusable keep-alive backend connections, re-adding the Upgrade and Connection headers while passing Content-Length verbatim. A backend that resolves the resulting...

netty: io.netty/netty-codec-http: Netty: Request smuggling via malformed Transfer-Encoding parsing

A flaw was found in Netty. This vulnerability allows a remote attacker to perform request smuggling attacks due to incorrect parsing of malformed Transfer-Encoding headers. By exploiting this flaw, an attacker can bypass security controls and potentially access sensitive information or manipulate...

netty: io.netty/netty-codec-http: Netty: HTTP Request Smuggling due to improper handling of conflicting HTTP/1.0 headers

A flaw was found in Netty's HttpObjectDecoder. A remote attacker can exploit this by sending a specially crafted HTTP/1.0 request that includes both Transfer-Encoding: chunked and Content-Length headers. While Netty correctly strips the conflicting Content-Length header for HTTP/1.1 messages, thi...

Security Bulletin: IBM Storage Protect Server is affected by a vulnerability in the netty-codec-http library.(CVE-2026-33870).

Summary IBM Storage Protect Server uses the netty-codec-http library in certain components. A vulnerability in netty could allow attacker to exploit the parsing flaw to craft requests that are interpreted differently by intermediaries and backend servers, resulting in HTTP request smuggling and...

CVE-2026-67289

FreeRDP before 3.29.0 affected versions = 3.28.0 does not validate CRLF and control characters in the server-controlled RDP redirection TargetNetAddress field. This value is copied into the client's ServerHostname and, when the client connects through an HTTP proxy, is written directly into the...

Security Bulletin: IBM Storage Protect Server is affected by multiple vulnerability in the netty-codec-http library that could allow an attacker to exploit integer overflow conditions when processing chunked HTTP requests(CVE-2026-42581, CVE-2026-42584).

Summary IBM Storage Protect Server uses the netty-codec-http library in certain components. Netty is vulnerable to multiple vulnerability that could allow an attacker to exploit integer overflow conditions when processing chunked HTTP requests. This may lead to inconsistent request parsing and...

CVE-2026-64785

A flaw was found in SwiftNIO HTTP/2. This vulnerability allows a remote attacker to perform HTTP request smuggling or response splitting. The issue stems from insufficient validation of incoming HTTP/2 HEADERS frames, which are parts of an HTTP/2 request. This allows special control characters,...

undici: undici: HTTP header injection via unvalidated blob-like body type property

A flaw was found in undici. An application that processes a hand-rolled blob-like request body with a type property derived from untrusted input may allow a remote attacker to inject Carriage Return Line Feed CRLF sequences. This vulnerability enables the attacker to append arbitrary HTTP headers...

nodejs: Node.js: Request smuggling via HTTP client header truncation

A flaw was found in Node.js. The Node.js HTTP client can cause a request desynchronization in forwarding proxies, potentially leading to request smuggling. This vulnerability arises when the HTTP client omits certain headers, such as Content-Length, from being visible to the proxy application whi...
