CVE-2026-73812
A flaw was found in the inets httpd server, part of Erlang/OTP. The server incorrectly processes HTTP requests that contain both Transfer-Encoding: chunked and Content-Length headers, failing to reject them or close the connection as required by RFC 9112 §6.1. When inets is deployed behind a...
CVE-2026-66752-HTTP-Request-Smuggling-via-Unparsed-Transfer-Encoding-Values-tiny_http-
安全公告:通过未解析的 Transfer-Encoding 值实现 HTTP 请求走私(tinyhttp) 分配的 CVE ID: CVE-2026-66752 摘要 tinyhttp 只检查是否存在 Transfer-Encoding 请求头,从不检查其值。任何值(包括不是 chunked 的编码,以及最终元素不是 chunked 的编码列表)都会导致请求体被按 chunked 解码,同时 Content-Length 会被丢弃。 正确解析传输编码的前端会以与 tinyhttp 不同的方式界定此类请求的边界。同一连接上两个参与者使用两种不同的边界界定方式,是请求走私的前提条件。发送带有...
Apache2 - Transfer-Encoding Chunked XSS
Apache2 PHP before 5.6.38, 7.0.x before 7.0.32, 7.1.x before 7.1.22, and 7.2.x before 7.2.10 contain a reflected cross-site scripting vulnerability caused by mishandling of chunked transfer-encoding requests in sapi/apache2handler/sapiapache2.c. Attackers can execute malicious scripts via crafted...

Here are some tests that can be performed against these services to observe different behavior on GET/POST routes between the patched and unpatched versions of Kestrel. GET against unpatched sends 200 and socket remains open root@kitploit: printf 'GET / HTTP/1.1\r\nHost:...
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...
CVE-2026-84380 HTTPX2: Conflicting Content-Length and Transfer-Encoding headers can be auto-generated
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
HTTPX2 , a next-generation HTTP client for Python, contains a request-smuggling vulnerability prior to version 2.11.0 . The flaw resides in Request._prepare() in _models.py, where its setdefault() logic checks Content-Length and Transfer-Encoding headers independently instead of treating them as ...

CVE-2026-73812
Erlang/OTP inets (HTTP server module) is vulnerable to HTTP Request Smuggling (CL.TE desync) when deployed behind a Content-Length-preferring front-end proxy. The root cause is in httpd:check_header/3 , which rejects duplicate Content-Length headers but never validates the simultaneous presence o...

CVE-2026-67181-HTTP-Request-Smuggling-via-Transfer-Encoding-Desynchronization-rouille-
安全公告:通过 Transfer-Encoding 去同步实现的 HTTP 请求走私(rouille) 分配的 CVE ID: CVE-2026-67181 摘要 rouille::proxy::proxy 将客户端的 Transfer-Encoding 头原样转发给后端,但写入的请求体却是 tinyhttp 已经去分块后的内容。它从不自行生成 Content-Length。后端被告知请求体是分块(chunked)的,收到的却是未分块的字节,因此决定后端认为请求体在哪里结束的是客户端,而不是 rouille。 受影响版本 仓库...
