CVE-2021-22959 4 Debian, Llhttp, Oracle and 1 more 7 Debian Linux, Llhttp, Graalvm and 4 more 2025-04-30 6.5 Medium
The parser in accepts requests with a space (SP) right after the header name before the colon. This can lead to HTTP Request Smuggling (HRS) in llhttp < v2.1.4 and < v6.0.6.
CVE-2020-8287 6 Debian, Fedoraproject, Nodejs and 3 more 7 Debian Linux, Fedora, Node.js and 4 more 2025-04-30 6.5 Medium
Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 allow 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-2020-8201 4 Fedoraproject, Nodejs, Opensuse and 1 more 6 Fedora, Node.js, Leap and 3 more 2025-04-30 7.4 High
Node.js < 12.18.4 and < 14.11 can be exploited to perform HTTP desync attacks and deliver malicious payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the underlying system. The attack was possible due to a bug in processing of carrier-return symbols in the HTTP header names.
CVE-2019-15605 6 Debian, Fedoraproject, Nodejs and 3 more 16 Debian Linux, Fedora, Node.js and 13 more 2025-04-30 9.8 Critical

CVE-2017-7561 1 Redhat 1 Jboss Enterprise Application Platform 2025-04-20 N/A
Red Hat JBoss EAP version 3.0.7 through before 4.0.0.Beta1 is vulnerable to a server-side cache poisoning or CORS requests in the JAX-RS component resulting in a moderate impact.
CVE-2015-5740 3 Fedoraproject, Golang, Redhat 7 Fedora, Go, Enterprise Linux and 4 more 2025-04-20 N/A
The net/http library in net/http/transfer.go in Go before 1.4.3 does not properly parse HTTP headers, which allows remote attackers to conduct HTTP request smuggling attacks via a request with two Content-length headers.
CVE-2015-5739 3 Fedoraproject, Golang, Redhat 7 Fedora, Go, Enterprise Linux and 4 more 2025-04-20 N/A
The net/http library in net/textproto/reader.go in Go before 1.4.3 does not properly parse HTTP header keys, which allows remote attackers to conduct HTTP request smuggling attacks via a space instead of a hyphen, as demonstrated by "Content Length" instead of "Content-Length."
CVE-2017-12158 2 Keycloak, Redhat 5 Keycloak, Enterprise Linux Server, Jboss Single Sign On and 2 more 2025-04-20 N/A
It was found that Keycloak would accept a HOST header URL in the admin console and use it to determine web resource locations. An attacker could use this flaw against an authenticated user to attain reflected XSS via a malicious server.
CVE-2017-8894 1 Aeroadmin 1 Aeroadmin 2025-04-20 N/A
AeroAdmin 4.1 uses an insecure protocol (HTTP) to perform software updates. An attacker can hijack an update via man-in-the-middle in order to execute code in the machine.
CVE-2017-15643 1 Ikarussecurity 1 Ikarus Antivirus 2025-04-20 N/A
An active network attacker (MiTM) can achieve remote code execution on a machine that runs IKARUS Anti Virus 2.16.7. IKARUS AV for Windows uses cleartext HTTP for updates along with a CRC32 checksum and an update value for verification of the downloaded files. The attacker first forces the client to initiate an update transaction by modifying an update field within an HTTP 200 response, so that it refers to a nonexistent update. The attacker then modifies the HTTP 404 response so that it specifies a successfully found update, with a Trojan horse executable file (e.g., guardxup.exe) and the correct CRC32 checksum for that file.
CVE-2016-6816 2 Apache, Redhat 4 Tomcat, Enterprise Linux, Jboss Enterprise Application Platform and 1 more 2025-04-20 N/A
The code in Apache Tomcat 9.0.0.M1 to 9.0.0.M11, 8.5.0 to 8.5.6, 8.0.0.RC1 to 8.0.38, 7.0.0 to 7.0.72, and 6.0.0 to 6.0.47 that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other then their own.
CVE-2016-2086 2 Fedoraproject, Nodejs 2 Fedora, Node.js 2025-04-12 N/A
Node.js 0.10.x before 0.10.42, 0.12.x before 0.12.10, 4.x before 4.3.0, and 5.x before 5.6.0 allow remote attackers to conduct HTTP request smuggling attacks via a crafted Content-Length HTTP header.
CVE-2023-27491 2 Envoyproxy, Redhat 2 Envoy, Service Mesh 2025-02-11 5.4 Medium
Envoy is an open source edge and service proxy designed for cloud-native applications. Compliant HTTP/1 service should reject malformed request lines. Prior to versions 1.26.0, 1.25.3, 1.24.4, 1.23.6, and 1.22.9, There is a possibility that non compliant HTTP/1 service may allow malformed requests, potentially leading to a bypass of security policies. This issue is fixed in versions 1.26.0, 1.25.3, 1.24.4, 1.23.6, and 1.22.9.
CVE-2020-10109 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2024-11-25 9.8 Critical
In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request.
CVE-2020-10108 6 Canonical, Debian, Fedoraproject and 3 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-25 9.8 Critical
In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request.
CVE-2021-46825 1 Broadcom 2 Advanced Secure Gateway, Proxysg 2024-11-21 9.1 Critical
Symantec Advanced Secure Gateway (ASG) and ProxySG are susceptible to an HTTP desync vulnerability. When a remote unauthenticated attacker and other web clients communicate through the proxy with the same web server, the attacker can send crafted HTTP requests and cause the proxy to forward web server responses to unintended clients. Severity/CVSSv3: High / 8.1 AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N
