CVE-2026-49753

Summary of the vulnerability : CVE-2026-49753 affects the Elixir Mint HTTP/1 client. The root cause is a lenient Content-Length parser in Mint.HTTP1.Parse.content_length_header/1, which accepts a leading + sign (e.g., +0, +123) despite RFC 7230 requiring unsigned digits only. When the same Mint c...

The iss...

curl: Proxy CONNECT response poisoning via authentication retry in cf-h1-proxy.c (libcurl)

Summary: When an HTTP/1.x proxy returns a 407 with no Content-Length and no chunked transfer-encoding, lib/cf-h1-proxy.c singleheader sets ts-keepon = KEEPONDONE but never sets ts-closeconnection = TRUE. Because ts-closeconnection and conn-bits.close both stay false, the CONNECT tunnel state...

CVE-2026-42581

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] Fedora 44 Update: nginx-mod-headers-more-0.39-10.fc44

This module allows adding, setting, or clearing specified input/output header s. This is an enhanced version of the standard headers module because it provides more utilities like resetting or clearing "builtin headers" like Content-Type, Content-Length, and Server...

An attacker can bypass body-inspection mechanisms and evade detection by manipulating HTTP request headers to omit or alter the Content-Length value, causing the...

CrowdSec AppSec silently drops request body for chunked / HTTP-2 requests

Summary The CrowdSec AppSec component fails to read the HTTP request body for any request whose Content-Length is not positive — most notably HTTP/1.1 requests using Transfer-Encoding: chunked and HTTP/2 requests sent without a content-length header. Coraza is then evaluated against an empty body...
