aiohttp: AIOHTTP: HTTP Request Smuggling via WebSocket Upgrade

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework. This vulnerability allows a remote attacker to perform HTTP request smuggling due to an edge case in the WebSocket upgrade procedure. When a WebSocket upgrade request includes a body, the parser may switch protocols before...

Astra Linux – Vulnerability in Netty

Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.129.Final and 4.2.8.Final, the io.netty.handler.codec.http.HttpRequestEncoder had a CRLF injection in the request URI during request construction. This led to request smuggling when HttpRequestEncoder w...

Astra Linux – Vulnerability in Twisted

In Twisted Web version 19.10.0, there was an HTTP request splitting vulnerability. When two content-length headers were provided, the system ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request...

Astra Linux – Vulnerability in Gunicorn

Gunicorn fails to properly validate Transfer-Encoding headers, resulting in HTTP Request Smuggling HRS vulnerabilities. By creating requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue arises due to Gunicorn’s...

Astra Linux – Vulnerability in Puma

Puma is a Ruby/Rack web server designed for parallelism. Prior to versions 6.3.1 and 5.6.7, Puma exhibited incorrect behavior when parsing chunked transfer encoding bodies and zero-length Content-Length headers, which could allow HTTP request smuggling. The severity of this issue depends heavily ...

Astra Linux – Vulnerability in Puma

Puma is an HTTP 1.1 server for Ruby/Rack applications. Prior to versions 5.5.1 and 4.3.9, using “puma” with a proxy that forwards HTTP header values containing the LF character could lead to HTTP request smuggling. A client could secretly send a request through a proxy, causing the proxy to send ...

Astra Linux – Vulnerability in http-parser

Node.js versions before 10.23.1, 12.20.1, 14.15.4, and 15.5.1 allow for two copies of a header field in an HTTP request for example, two Transfer-Encoding header fields. In this case, Node.js identifies the first header field and ignores the second. This can lead to HTTP Request Smuggling...

CVE-2026-78169

A vulnerability was detected in UTT HiPER 1250GW up to 3.2.7-210907-180535. This impacts the function strcpy of the file /goform/aspRemoteApConfTempSend of the component HTTP Request Handler. Performing a manipulation of the argument Profile results in stack-based buffer overflow. The attack is...

CVE-2026-78169

A stack-based buffer overflow in the UTT HiPER 1250GW (up to 3.2.7-210907-180535 ) affects the strcpy function within the file /goform/aspRemoteApConfTempSend of the HTTP Request Handler component. Manipulation of the Profile argument triggers the overflow, allowing a remote attack. CVSS 4.0 rate...

Name of the Vulnerable Software and Affected Versions UTT HiPER 1250GW versions prior to 3.2.7-210907-180535 Description An issue exists in the HTTP Request Handler component where a stack-based buffer overflow occurs. This happens when the strcpy function in the '/goform/aspRemoteApConfTempSend'...

CVE-2026-75922

Reverse::Proxy versions before 0.04 for Perl allow HTTP request smuggling via a percent-decoded PATHINFO written unencoded to the upstream request line. PSGI hands PATHINFO to an application percent-decoded, so a %XX sequence in the client URL has become a raw byte by the time the proxy sees it...

CVE-2026-75922

Reverse::Proxy (CPAN module by LNATION) versions before 0.04 for Perl are vulnerable to HTTP request smuggling via a percent-decoded PATH_INFO written unencoded into the upstream request line. Because PSGI delivers PATH_INFO already decoded, a client-controlled %0d%0a in the URL becomes a raw CRL...

SUSE CVE-2026-63382

Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, the libevent evhttp parser in http.c inconsistently handles duplicate Transfer-Encoding headers, comma-separated Transfer-Encoding values, and bare line feeds in chunked framing. evhttpfindheader can select only the first...
