Astra Linux – Vulnerability in Python 3.11

When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially leading to Out-of-Memory errors or other types of...

Astra Linux – Vulnerability in Erlang

Inconsistent interpretation of HTTP requests: The “HTTP Request Smuggling” vulnerability in Erlang OTP inets httpd module allows for HTTP requests to be disguised. This vulnerability is associated with the program file lib/inets/src/httpserver/httpdrequest.erl and the routine...

Astra Linux – Vulnerability in libsoup3

There is a vulnerability related to request smuggling in LibSoup’s HTTP/1 header parsing logic. The soupmessageheaders.AppendCommon function in libsoup/soup-message-headers.c appends each header value unconditionally, without checking for duplicates or conflicting Content-Length fields. This allo...

nghttp2: nghttp2: HTTP Request/Response Smuggling and Response-Queue Poisoning via ambiguous HTTP/1.1 Upgrade requests

A flaw in nghttp2's nghttpx proxy allows a remote attacker to perform HTTP request smuggling and cross-client response-queue poisoning. This occurs because the proxy ambiguously forwards HTTP/1.1 Upgrade requests that contain a Content-Length header to reusable keep-alive backend connections...

AI-Assisted HTTP Terminator Finds Novel HTTP Desync Techniques and Apache Zero-Day

PortSwigger says HTTP Terminator, an artificial intelligence AI-assisted research system built by James Kettle , generated and proved new HTTP desynchronization techniques after exploring 30,000 candidate desync vectors. PortSwigger said a separate human-guided discovery cascade also exposed a...

HTTP Response Desynchronization

undici is vulnerable to HTTP Response Desynchronization. The vulnerability is due to improper Content-Length handling after retrying or resuming partial responses, where a stale length can be retained for a differently sized response body, potentially causing downstream response desynchronization...

Linux Distros Unpatched Vulnerability : CVE-2026-45103

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - OpenSIPS is a Session Initiation Protocol SIP server implementation. In versions prior to 3.6.6 and 4.0.0-rc1, the TCP message framing layer parses the...

CVE-2026-9190

An HTTP request smuggling vulnerability in the HTTP App Server of Progress MarkLogic Server before 11.3.6 and 12.0.3 allows a remote attacker to bypass authentication and authorization checks, hijack a legitimate user's session, or capture credentials. The vulnerability occurs when a crafted HTTP...

CVE-2026-9190

Progress MarkLogic Server versions before 11.3.6 and 12.0.3 contain an HTTP request smuggling flaw in the HTTP App Server. A crafted request with both Content-Length and Transfer-Encoding headers can cause the reverse proxy and MarkLogic Server to misinterpret request boundaries, enabling an atta...

CVE-2026-9190 HTTP request smuggling in Progress MarkLogic Server

An HTTP request smuggling vulnerability in the HTTP App Server of Progress MarkLogic Server before 11.3.6 and 12.0.3 allows a remote attacker to bypass authentication and authorization checks, hijack a legitimate user's session, or capture credentials. The vulnerability occurs when a crafted HTTP...

axios: axios: Denial of Service via maxBodyLength bypass with ReadableStream

A flaw was found in axios. This vulnerability allows a remote attacker to bypass configured upload size limits by supplying unknown-length stream data when using WHATWG ReadableStream request bodies in the fetch adapter, specifically when the Content-Length cannot be determined. This can lead to...

CVE-2026-45103

OpenSIPS is a Session Initiation Protocol SIP server implementation. In versions prior to 3.6.6 and 4.0.0-rc1, the TCP message framing layer parses the Content-Length header using unsigned int arithmetic with no overflow check. When an attacker sends a Content-Length value that overflows unsigned...

CVE-2026-16728

A flaw was found in undici. A malicious or faulty upstream server could send a partial response with incorrect length information. When undici's retry interceptor processes this, it may create a response body with a length that does not match the original Content-Length header. This can lead to...

HTTP Request Smuggling

Overview Affected versions of this package are vulnerable to HTTP Request Smuggling in the HTTP client when forwarding proxies rebuild outbound headers from the visible IncomingMessage headers while piping the original body to a reused backend connection. An attacker can manipulate HTTP request...

ALPINE-CVE-2026-58044

A flaw in Node.js HTTP client can cause a request desynchronization for Node.js-based forwarding proxies that rebuild outbound headers from the visible IncomingMessage headers while piping the original body to a reused backend connection. Node.js can omit headers beyond maxHeadersCount /...
