curl: HTTP/1.1 Response Desynchronization via conflicting CL/TE headers in Proxy CONNECT

Summary: curl fails to prioritize the Transfer-Encoding: chunked header over Content-Length in HTTP/1.1 proxy responses specifically 407/401 auth challenges, violating RFC 9112 Section 6.1. I have identified the root cause in cf-h1-proxy.c. In the response-handling loop around line 466, the code...

CVE-2026-32881 ewe has an Overly Permissive List of Allowed Inputs

ewe is a Gleam web server. ewe is a Gleam web server. Versions 0.6.0 through 3.0.4 are vulnerable to authentication bypass or spoofed proxy-trust headers. Chunked transfer encoding trailer handling merges declared trailer fields into req.headers after body parsing, but the denylist only blocks 9...

CVE-2026-29057

A request smuggling flaw has been discovered in Next.js. when Next.js rewrites proxy traffic to an external backend, a crafted DELETE/OPTIONS request using Transfer-Encoding: chunked could trigger request boundary disagreement between the proxy and backend. This could allow request smuggling...

GHSA-GGV3-7P47-PFV8 Next.js: HTTP request smuggling in rewrites

Summary When Next.js rewrites proxy traffic to an external backend, a crafted DELETE/OPTIONS request using Transfer-Encoding: chunked could trigger request boundary disagreement between the proxy and backend. This could allow request smuggling through rewritten routes. Impact An attacker could...

GHSA-4W98-XF39-23GP Loop with Unreachable Exit Condition ('Infinite Loop') in ewe

Summary ewe's handletrailers function contains a bug where rejected trailer headers forbidden or undeclared cause an infinite loop. The function recurses with the original unparsed buffer instead of advancing past the rejected header, re-parsing the same header forever. Each malicious request...

SUSE CVE-2026-32240

Cap'n Proto is a data interchange format and capability-based RPC system. Prior to 1.4.0, when using Transfer-Encoding: chunked, if a chunk's size parsed to a value of 2^64 or larger, it would be truncated to a 64-bit integer. In theory, this bug could enable HTTP request/response smuggling. This...

netty-codec-http: Netty is vulnerable to request smuggling due to incorrect parsing of chunk extensions

A flaw in Netty’s HTTP/1.1 chunked encoding parser allows newline LF characters in chunk extensions to be incorrectly treated as the end of the chunk-size line instead of requiring the proper CRLF sequence. This discrepancy can be exploited in rare cases where a reverse proxy interprets the same...
