SUSE CVE-2024-14029

Tornado before 6.4.1 ignores duplicate Transfer-Encoding: chunked headers, treating requests as having no message body and parsing the chunked body as a subsequent request. Attackers can exploit this inconsistency when Tornado is deployed behind proxies to perform HTTP request smuggling, enabling...

CVE-2026-56866

When http.Transport sends an HTTP/1 CONNECT request with a non-empty Request.Body, it writes the body directly to the connection without framing after the request headers. If the server rejects the CONNECT request with a non-2xx keep-alive response, Transport returns the connection to the idle...

CVE-2026-94439 HTTP/1 server connection desynchronization after 2xx CONNECT response in net/http

When an HTTP server handler sends a 2xx response to an HTTP/1 CONNECT request and returns without hijacking the connection, the server improperly continues to read and serve requests from the connection. Since a 2xx response to an HTTP/1 CONNECT converts the connection into a tunnel, the server...

CVE-2026-94439

An HTTP server handler is vulnerable to request smuggling because it improperly handles HTTP/1 CONNECT requests. When the handler sends a 2xx response without hijacking the connection, it fails to stop treating the connection as HTTP, even though it has been converted into a tunnel. This discrepa...

CVE-2026-94439 HTTP/1 server connection desynchronization after 2xx CONNECT response in net/http

CVE-2026-56866 HTTP/1 client connection desynchronization after CONNECT rejection in net/http

When http.Transport sends an HTTP/1 CONNECT request with a non-empty Request.Body, it writes the body directly to the connection without framing after the request headers. If the server rejects the CONNECT request with a non-2xx keep-alive response, Transport returns the connection to the idle...

GO-2026-6605 HTTP/1 client connection desynchronization after CONNECT rejection in net/http

When http.Transport sends an HTTP/1 CONNECT request with a non-empty Request.Body, it writes the body directly to the connection without framing after the request headers. If the server rejects the CONNECT request with a non-2xx keep-alive response, Transport returns the connection to the idle...

CVE-2024-14029

A vulnerability was discovered in Tornado where it improperly handles HTTP requests containing duplicate Transfer-Encoding: chunked headers. When duplicate Transfer-Encoding headers are present in an incoming request, Tornado ignores them and treats the request as body-less, leaving the chunked...

CVE-2026-69204

CVE-2026-69204 affects Http4s , a Scala HTTP library, specifically the Ember HTTP/1.1 implementation. The root cause is that Ember does not reject messages containing both Transfer-Encoding and Content-Length headers, allowing an intermediary and Ember to select different body framing rules. This...

CVE-2024-14029

Tornado before 6.4.1 ignores duplicate Transfer-Encoding: chunked headers, causing the server to treat a request as having no message body and parse the chunked body as a subsequent request. When Tornado is deployed behind a proxy, this inconsistency enables HTTP request smuggling , which can lea...

UBUNTU-CVE-2026-90678

An issue was discovered in HAProxy 3.3.0 through 3.4.4 and in 3.5-dev1 through 3.5-dev5. Exploitation requires an HTTP/3 frontend: HAProxy must be built with QUIC support and configured with a QUIC bind listener, and the affected traffic must reach a backend over HTTP/1.1 using chunked transfer...

HTTPX2: Conflicting Content-Length and Transfer-Encoding headers can be auto-generated...

SUSE CVE-2026-84380

HTTPX2 is a next generation HTTP client for Python. Prior to 2.11.0, Request.prepare in src/httpx2/httpx2/models.py can add a body-derived Content-Length header to a request that already contains a caller-supplied Transfer-Encoding header because its setdefault processing checks each default head...

CVE-2026-84380

A flaw was found in HTTPX2, a Python HTTP client. The Request.prepare function can incorrectly add a Content-Length header to a request that already includes a Transfer-Encoding header. This conflict in HTTP framing headers can lead to request smuggling or connection desynchronization. This could...
