The netty incubator codec.bhttp is a java language binary http parser. Prior to version 0.0.22.FInal, the codec-ohttp implementation of draft-ietf-ohai-chunked-ohttp does not verify that a cryptographically-signed final chunk was received before the outer HTTP body terminates. An on-path adversar...

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 DoS via chunked request trailers in Bandit HTTP/1 decoder

Summary A worker-pinning denial of service in Bandit's HTTP/1 chunked transfer decoder. Any unauthenticated client that sends a Transfer-Encoding: chunked request whose body ends with a trailer field RFC 9112 §7.1.2 explicitly permits this causes the connection's worker process to spin forever in...

GHSA-9Q9Q-324X-93R2 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...

CVE-2026-39803

CVE-2026-39803 – Bandit (Elixir) memory exhaustion via chunked HTTP/1 bodies. The issue occurs in the chunked path of Elixir.Bandit.HTTP1.Socket.read_data/2 where the caller-supplied length is ignored; every received chunk is buffered into an iolist and the entire body is materialized as a single...

CVE-2026-45185

A flaw was found in Exim. An unauthenticated remote attacker could exploit a use-after-free vulnerability in the BDAT body parsing path when a client sends a TLS closenotify mid-body during a CHUNKING transfer, followed by a final cleartext byte on the same TCP connection. This can lead to heap...
