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...
curl: Incomplete Suppression of Transfer-Encoding: chunked Header in HTTP/2 After Redirect From HTTP/1.1
When curl send a request with Transfer-Encoding: chunked using HTTP/1.1, and follows a redirect to an HTTP/2 endpoint, the uploadchunky flag is not properly reset. As a result, the Transfer-Encoding: chunked header is sent in the subsequent request even when HTTP/2 is negotiated/used. This violat...
USN-8401-1: Netty vulnerabilities
It was discovered that Netty's HTTP proxy handler did not properly validate headers when constructing CONNECT requests. An attacker could possibly use this issue to inject arbitrary HTTP headers into CONNECT requests. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS,...
SUSE CVE-2026-45352

CVE-2026-45352
The CVE-2026-45352 issue affects cpp-httplib (header-only HTTP/HTTPS library). Before version 0.43.4, the ChunkedDecoder::read_payload routine parses the chunk-size in chunked Transfer-Encoding with std::strtoul(), which can silently accept a minus sign. This allows negative chunk sizes (e.g., "-...

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...

Bandit: Unauthenticated one-shot DoS via `Transfer-Encoding: chunked`
Summary Bandit's HTTP/1 chunked-body reader silently drops the request size cap that the application configures e.g. Plug.Parsers' default 8 MB length: and buffers the entire body in memory before the application sees it. An unauthenticated attacker can crash any Bandit-fronted Phoenix/Plug app...
