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 Jetty9

Jetty is a Java-based web server and servlet engine. Prior to versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1, Jetty accepted the + character that followed the content-length value in an HTTP/1 header field. This was more permissive than what is allowed by the RFC, and other servers routinely...

Astra Linux – Vulnerability in Apache2

Inconsistent interpretation of HTTP requests: The “HTTP Request Smuggling” vulnerability in modproxyajp of the Apache HTTP Server allows an attacker to secretly send requests to the AJP server to which the server forwards requests. This issue affects the Apache HTTP Server version 2.4.53 and...

Astra Linux – Vulnerability in Tomcat9

Apache Tomcat versions 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46, and 8.5.0 to 8.5.66 failed to properly parse the HTTP transfer-encoding request header under certain circumstances, which could lead to requests for data smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly...

Astra Linux – Vulnerability in JRuby

A vulnerability was discovered in Ruby versions 2.5.8, 2.6.x up to 2.6.6, and 2.7.x up to 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, did not rigorously check the transfer-encoding header value. An attacker could potentially exploit this vulnerability to bypass a reverse proxy which...

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 Netty

Netty is an asynchronous, event-driven network application framework for developing maintainable, high-performance protocol servers and clients. In versions 4.1.124.Final and 4.2.0.Alpha3 through 4.2.4.Final, Netty incorrectly accepts standalone newline characters LF as a chunk-size line...

Astra Linux – Vulnerability in Waitress

Waitress, in version 1.3.1, implemented a “MAY” clause from RFC7230. This clause states: “Although the line terminator for the start-line and header fields is the sequence CRLF, a recipient MAY recognize a single LF as a line terminator and ignore any preceding CR.” Unfortunately, if a front-end...

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 HAPProxy

Before version 2.7.3, HAProxy might allow a bypass of access control mechanisms, as HTTP/1 headers were inadvertently lost in certain situations, also known as “request smuggling.” The HTTP header parsers in HAProxy might accept empty header field names, which could be used to omit the list of HT...

Astra Linux – Vulnerability in Tomcat9

There is a vulnerability related to improper input validation in Apache Tomcat. In versions of Tomcat from 11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through 10.1.15, from 9.0.0-M1 through 9.0.82, and from 8.5.0 through 8.5.95, HTTP trailer headers were not parsed correctly. A trailer header th...

Astra Linux – Vulnerability in Waitress

In Waitress version 1.4.0, if a proxy server is used in front of Waitress, an attacker may send an invalid request that bypasses the front-end and is parsed differently by Waitress. This could lead to HTTP request smuggling. Specifically, requests containing special whitespace characters in the...

Astra Linux – Vulnerability in Netty

Netty is an asynchronous, event-driven network application framework designed for rapid development of maintainable, high-performance protocol servers and clients. In versions prior to 4.1.71.Final, Netty would skip control characters when they appeared at the beginning or end of a header name...

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

HTTP request smuggling in Node.js versions 10, 12, and 13 causes the delivery of malicious payloads when transfer-encoding is malformed...

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 versions before 0.04 for Perl allow HTTP request smuggling via a percent-decoded PATH_INFO written unencoded to the upstream request line

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...

EUVD-2026-64662

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...
