CVE-2022-0552 1 Redhat 1 Origin-aggregated-logging 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
A flaw was found in the original fix for the netty-codec-http CVE-2021-21409, where the OpenShift Logging openshift-logging/elasticsearch6-rhel8 container was incomplete. The vulnerable netty-codec-http maven package was not removed from the image content. This flaw affects origin-aggregated-logging versions 3.11.
CVE-2021-46825 1 Broadcom 2 Advanced Secure Gateway, Proxysg 2026-06-17 6.4 MEDIUM 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
CVE-2021-45468 1 Imperva 1 Web Application Firewall 2026-06-17 7.5 HIGH 9.8 CRITICAL
Imperva Web Application Firewall (WAF) before 2021-12-23 allows remote unauthenticated attackers to use "Content-Encoding: gzip" to evade WAF security controls and send malicious HTTP POST requests to web servers behind the WAF.
CVE-2021-43797 5 Debian, Netapp, Netty and 2 more 18 Debian Linux, Oncommand Workflow Automation, Snapcenter and 15 more 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Netty prior to version 4.1.71.Final skips control chars when they are present at the beginning / end of the header name. It should instead fail fast as these are not allowed by the spec and could lead to HTTP request smuggling. Failing to do the validation might cause netty to "sanitize" header names before it forward these to another remote system when used as proxy. This remote system can't see the invalid usage anymore, and therefore does not do the validation itself. Users should upgrade to version 4.1.71.Final.
CVE-2021-43669 1 Linuxfoundation 1 Fabric 2026-06-17 5.0 MEDIUM 7.5 HIGH
A vulnerability has been detected in HyperLedger Fabric v1.4.0, v2.0.0, v2.0.1, v2.3.0. It can easily break down as many orderers as the attacker wants. This bug can be leveraged by constructing a message whose header is invalid to the interface Order. This bug has been admitted and fixed by the developers of Fabric.
CVE-2021-43610 1 Linphone 1 Belle-sip 2026-06-17 5.0 MEDIUM 7.5 HIGH
Belledonne Belle-sip before 5.0.20 can crash applications such as Linphone via an invalid From header (request URI without a parameter) in an unauthenticated SIP message, a different issue than CVE-2021-33056.
CVE-2021-42791 1 Veridiumid 1 Veridiumad 2026-06-17 4.9 MEDIUM 7.3 HIGH
An issue was discovered in VeridiumID VeridiumAD 2.5.3.0. The HTTP request to trigger push notifications for VeridiumAD enrolled users does not enforce proper access control. A user can trigger push notifications for any other user. The text contained in the push notification can also be modified. If a user who receives the notification accepts it, then the user who triggered the notification can obtain the accepting user's login certificate.
CVE-2021-41732 1 Zeek 1 Zeek 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue was discovered in zeek version 4.1.0. There is a HTTP request splitting vulnerability that will invalidate any ZEEK HTTP based security analysis. NOTE: the vendor's position is that the observed behavior is intended
CVE-2021-41267 1 Sensiolabs 1 Symfony 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
Symfony/Http-Kernel is the HTTP kernel component for Symfony, a PHP framework for web and console applications and a set of reusable PHP components. Headers that are not part of the "trusted_headers" allowed list are ignored and protect users from "Cache poisoning" attacks. In Symfony 5.2, maintainers added support for the `X-Forwarded-Prefix` headers, but this header was accessible in SubRequest, even if it was not part of the "trusted_headers" allowed list. An attacker could leverage this opportunity to forge requests containing a `X-Forwarded-Prefix` header, leading to a web cache poisoning issue. Versions 5.3.12 and later have a patch to ensure that the `X-Forwarded-Prefix` header is not forwarded to subrequests when it is not trusted.
CVE-2021-41136 2 Debian, Puma 2 Debian Linux, Puma 2026-06-17 3.6 LOW 3.7 LOW
Puma is a HTTP 1.1 server for Ruby/Rack applications. Prior to versions 5.5.1 and 4.3.9, using `puma` with a proxy which forwards HTTP header values which contain the LF character could allow HTTP request smugggling. A client could smuggle a request through a proxy, causing the proxy to send a response back to another unknown client. The only proxy which has this behavior, as far as the Puma team is aware of, is Apache Traffic Server. If the proxy uses persistent connections and the client adds another request in via HTTP pipelining, the proxy may mistake it as the first request's body. Puma, however, would see it as two requests, and when processing the second request, send back a response that the proxy does not expect. If the proxy has reused the persistent connection to Puma to send another request for a different client, the second response from the first client will be sent to the second client. This vulnerability was patched in Puma 5.5.1 and 4.3.9. As a workaround, do not use Apache Traffic Server with `puma`.
CVE-2021-39214 1 Mitmproxy 1 Mitmproxy 2026-06-17 7.5 HIGH 8.1 HIGH
mitmproxy is an interactive, SSL/TLS-capable intercepting proxy. In mitmproxy 7.0.2 and below, a malicious client or server is able to perform HTTP request smuggling attacks through mitmproxy. This means that a malicious client/server could smuggle a request/response through mitmproxy as part of another request/response's HTTP message body. While a smuggled request is still captured as part of another request's body, it does not appear in the request list and does not go through the usual mitmproxy event hooks, where users may have implemented custom access control checks or input sanitization. Unless one uses mitmproxy to protect an HTTP/1 service, no action is required. The vulnerability has been fixed in mitmproxy 7.0.3 and above.
CVE-2021-38512 2 Actix, Fedoraproject 2 Actix-http, Fedora 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue was discovered in the actix-http crate before 3.0.0-beta.9 for Rust. HTTP/1 request smuggling (aka HRS) can occur, potentially leading to credential disclosure.
CVE-2021-38162 1 Sap 1 Web Dispatcher 2026-06-17 7.5 HIGH 8.9 HIGH
SAP Web Dispatcher versions - 7.49, 7.53, 7.77, 7.81, KRNL64NUC - 7.22, 7.22EXT, 7.49, KRNL64UC -7.22, 7.22EXT, 7.49, 7.53, KERNEL - 7.22, 7.49, 7.53, 7.77, 7.81, 7.83 processes allow an unauthenticated attacker to submit a malicious crafted request over a network to a front-end server which may, over several attempts, result in a back-end server confusing the boundaries of malicious and legitimate messages. This can result in the back-end server executing a malicious payload which can be used to read or modify any information on the server or consume server resources making it temporarily unavailable.
CVE-2021-37253 1 M-files 1 M-files Web 2026-06-17 7.8 HIGH 7.5 HIGH
M-Files Web before 20.10.9524.1 allows a denial of service via overlapping ranges (in HTTP requests with crafted Range or Request-Range headers). NOTE: this is disputed because the range behavior is the responsibility of the web server, not the responsibility of the individual web application
CVE-2021-37147 2 Apache, Debian 2 Traffic Server, Debian Linux 2026-06-17 5.0 MEDIUM 7.5 HIGH
Improper input validation vulnerability in header parsing of Apache Traffic Server allows an attacker to smuggle requests. This issue affects Apache Traffic Server 8.0.0 to 8.1.2 and 9.0.0 to 9.1.0.
CVE-2021-36740 5 Debian, Fedoraproject, Varnish-cache and 2 more 5 Debian Linux, Fedora, Varnish Cache and 2 more 2026-06-17 6.4 MEDIUM 6.5 MEDIUM
Varnish Cache, with HTTP/2 enabled, allows request smuggling and VCL authorization bypass via a large Content-Length header for a POST request. This affects Varnish Enterprise 6.0.x before 6.0.8r3, and Varnish Cache 5.x and 6.x before 6.5.2, 6.6.x before 6.6.1, and 6.0 LTS before 6.0.8.
CVE-2021-34559 1 Pepperl-fuchs 4 Wha-gw-f2d2-0-as-z2-eth, Wha-gw-f2d2-0-as-z2-eth.eip, Wha-gw-f2d2-0-as-z2-eth.eip Firmware and 1 more 2026-06-17 5.0 MEDIUM 5.4 MEDIUM
In PEPPERL+FUCHS WirelessHART-Gateway <= 3.0.8 a vulnerability may allow remote attackers to rewrite links and URLs in cached pages to arbitrary strings.
CVE-2021-33683 1 Sap 2 Internet Communication Manager, Web Dispatcher 2026-06-17 4.0 MEDIUM 4.3 MEDIUM
SAP Web Dispatcher and Internet Communication Manager (ICM), versions - KRNL32NUC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL32UC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL64NUC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, KRNL64UC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.53, 7.73, WEBDISP 7.53, 7.73, 7.77, 7.81, 7.82, 7.83, KERNEL 7.21, 7.22, 7.49, 7.53, 7.73, 7.77, 7.81, 7.82, 7.83, process invalid HTTP header. The incorrect handling of the invalid Transfer-Encoding header in a particular manner leads to a possibility of HTTP Request Smuggling attack. An attacker could exploit this vulnerability to bypass web application firewall protection, divert sensitive data such as customer requests, session credentials, etc.
CVE-2021-33056 1 Linphone 1 Belle-sip 2026-06-17 5.0 MEDIUM 7.5 HIGH
Belledonne Belle-sip before 4.5.20, as used in Linphone and other products, can crash via an invalid From header in a SIP message.
CVE-2021-33037 4 Apache, Debian, Mcafee and 1 more 22 Tomcat, Tomee, Debian Linux and 19 more 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
