| CVE-2025-55315 | 2 Microsoft, Redhat | 4 Asp.net Core, Visual Studio, Visual Studio 2022 and 1 more | 2025-11-22 | 9.9 Critical |
| Inconsistent interpretation of http requests ('http request/response smuggling') in ASP.NET Core allows an authorized attacker to bypass a security feature over a network. | ||||
| CVE-2024-9622 | 1 Redhat | 3 Jboss Data Grid, Jboss Enterprise Application Platform, Jbosseapxp | 2025-11-21 | 5.3 Medium |
| A vulnerability was found in the resteasy-netty4 library arising from improper handling of HTTP requests using smuggling techniques. When an HTTP smuggling request with an ASCII control character is sent, it causes the Netty HttpObjectDecoder to transition into a BAD_MESSAGE state. As a result, any subsequent legitimate requests on the same connection are ignored, leading to client timeouts, which may impact systems using load balancers and expose them to risk. | ||||
| CVE-2025-0752 | 1 Redhat | 2 Openshift Service Mesh, Service Mesh | 2025-11-20 | 6.3 Medium |
| A flaw was found in OpenShift Service Mesh 2.6.3 and 2.5.6. Rate-limiter avoidance, access-control bypass, CPU and memory exhaustion, and replay attacks may be possible due to improper HTTP header sanitization in Envoy. | ||||
| CVE-2023-46846 | 2 Redhat, Squid-cache | 13 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 10 more | 2025-11-20 | 9.3 Critical |
| SQUID is vulnerable to HTTP request smuggling, caused by chunked decoder lenience, allows a remote attacker to perform Request/Response smuggling past firewall and frontend security systems. | ||||
| CVE-2025-12642 | 1 Lighttpd | 1 Lighttpd | 2025-11-12 | 9.1 Critical |
| lighttpd1.4.80 incorrectly merged trailer fields into headers after http request parsing. This behavior can be exploited to conduct HTTP Header Smuggling attacks. Successful exploitation may allow an attacker to: * Bypass access control rules * Inject unsafe input into backend logic that trusts request headers * Execute HTTP Request Smuggling attacks under some conditions This issue affects lighttpd1.4.80 | ||||
| CVE-2024-9666 | 1 Redhat | 2 Build Keycloak, Jboss Enterprise Application Platform | 2025-11-11 | 4.7 Medium |
| A vulnerability was found in the Keycloak Server. The Keycloak Server is vulnerable to a denial of service (DoS) attack due to improper handling of proxy headers. When Keycloak is configured to accept incoming proxy headers, it may accept non-IP values, such as obfuscated identifiers, without proper validation. This issue can lead to costly DNS resolution operations, which an attacker could exploit to tie up IO threads and potentially cause a denial of service. The attacker must have access to send requests to a Keycloak instance that is configured to accept proxy headers, specifically when reverse proxies do not overwrite incoming headers, and Keycloak is configured to trust these headers. | ||||
| CVE-2024-12397 | 1 Redhat | 13 Amq Streams, Apache Camel Hawtio, Build Keycloak and 10 more | 2025-11-11 | 7.4 High |
| A flaw was found in Quarkus-HTTP, which incorrectly parses cookies with certain value-delimiting characters in incoming requests. This issue could allow an attacker to construct a cookie value to exfiltrate HttpOnly cookie values or spoof arbitrary additional cookie values, leading to unauthorized data access or modification. The main threat from this flaw impacts data confidentiality and integrity. | ||||
| CVE-2024-27982 | 2 Nodejs, Redhat | 3 Node.js, Enterprise Linux, Rhel Eus | 2025-11-04 | 6.1 Medium |
| The team has identified a critical vulnerability in the http server of the most recent version of Node, where malformed headers can lead to HTTP request smuggling. Specifically, if a space is placed before a content-length header, it is not interpreted correctly, enabling attackers to smuggle in a second request within the body of the first. | ||||
| CVE-2024-8925 | 2 Php, Redhat | 2 Php, Enterprise Linux | 2025-11-03 | 3.1 Low |
| In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, 8.3.* before 8.3.12, erroneous parsing of multipart form data contained in an HTTP POST request could lead to legitimate data not being processed. This could lead to malicious attacker able to control part of the submitted data being able to exclude portion of other data, potentially leading to erroneous application behavior. | ||||
| CVE-2024-52530 | 2 Gnome, Redhat | 7 Libsoup, Enterprise Linux, Rhel Aus and 4 more | 2025-11-03 | 7.5 High |
| GNOME libsoup before 3.6.0 allows HTTP request smuggling in some configurations because '\0' characters at the end of header names are ignored, i.e., a "Transfer-Encoding\0: chunked" header is treated the same as a "Transfer-Encoding: chunked" header. | ||||
| CVE-2024-45614 | 1 Puma | 1 Puma | 2025-11-03 | 5.4 Medium |
| Puma is a Ruby/Rack web server built for parallelism. In affected versions clients could clobber values set by intermediate proxies (such as X-Forwarded-For) by providing a underscore version of the same header (X-Forwarded_For). Any users relying on proxy set variables is affected. v6.4.3/v5.6.9 now discards any headers using underscores if the non-underscore version also exists. Effectively, allowing the proxy defined headers to always win. Users are advised to upgrade. Nginx has a underscores_in_headers configuration variable to discard these headers at the proxy level as a mitigation. Any users that are implicitly trusting the proxy defined headers for security should immediately cease doing so until upgraded to the fixed versions. | ||||
| CVE-2024-41671 | 1 Twisted | 1 Twisted | 2025-11-03 | 8.3 High |
| Twisted is an event-based framework for internet applications, supporting Python 3.6+. The HTTP 1.0 and 1.1 server provided by twisted.web could process pipelined HTTP requests out-of-order, possibly resulting in information disclosure. This vulnerability is fixed in 24.7.0rc1. | ||||
| CVE-2024-35161 | 1 Apache | 1 Traffic Server | 2025-11-03 | 9.1 Critical |
| Apache Traffic Server forwards malformed HTTP chunked trailer section to origin servers. This can be utilized for request smuggling and may also lead cache poisoning if the origin servers are vulnerable. This issue affects Apache Traffic Server: from 8.0.0 through 8.1.10, from 9.0.0 through 9.2.4. Users can set a new setting (proxy.config.http.drop_chunked_trailers) not to forward chunked trailer section. Users are recommended to upgrade to version 8.1.11 or 9.2.5, which fixes the issue. | ||||
| CVE-2024-21647 | 2 Puma, Redhat | 2 Puma, Satellite | 2025-11-03 | 5.9 Medium |
| Puma is a web server for Ruby/Rack applications built for parallelism. Prior to version 6.4.2, puma exhibited incorrect behavior when parsing chunked transfer encoding bodies in a way that allowed HTTP request smuggling. Fixed versions limits the size of chunk extensions. Without this limit, an attacker could cause unbounded resource (CPU, network bandwidth) consumption. This vulnerability has been fixed in versions 6.4.2 and 5.6.8. | ||||
| CVE-2023-46137 | 2 Redhat, Twisted | 3 Ansible Automation Platform, Openstack, Twisted | 2025-11-03 | 5.3 Medium |
| Twisted is an event-based framework for internet applications. Prior to version 23.10.0rc1, when sending multiple HTTP requests in one TCP packet, twisted.web will process the requests asynchronously without guaranteeing the response order. If one of the endpoints is controlled by an attacker, the attacker can delay the response on purpose to manipulate the response of the second request when a victim launched two requests using HTTP pipeline. Version 23.10.0rc1 contains a patch for this issue. | ||||
| CVE-2023-38522 | 1 Apache | 1 Traffic Server | 2025-11-03 | 7.5 High |
| Apache Traffic Server accepts characters that are not allowed for HTTP field names and forwards malformed requests to origin servers. This can be utilized for request smuggling and may also lead cache poisoning if the origin servers are vulnerable. This issue affects Apache Traffic Server: from 8.0.0 through 8.1.10, from 9.0.0 through 9.2.4. Users are recommended to upgrade to version 8.1.11 or 9.2.5, which fixes the issue. | ||||
| CVE-2024-52304 | 3 Aiohttp, Python, Redhat | 5 Aiohttp, Aiohttp, Ansible Automation Platform and 2 more | 2025-11-03 | 7.5 High |
| aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.10.11, the Python parser parses newlines in chunk extensions incorrectly which can lead to request smuggling vulnerabilities under certain conditions. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or `AIOHTTP_NO_EXTENSIONS` is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.10.11 fixes the issue. | ||||
| CVE-2024-23829 | 3 Aiohttp, Fedoraproject, Redhat | 6 Aiohttp, Fedora, Ansible Automation Platform and 3 more | 2025-11-03 | 6.5 Medium |
| aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Security-sensitive parts of the Python HTTP parser retained minor differences in allowable character sets, that must trigger error handling to robustly match frame boundaries of proxies in order to protect against injection of additional requests. Additionally, validation could trigger exceptions that were not handled consistently with processing of other malformed input. Being more lenient than internet standards require could, depending on deployment environment, assist in request smuggling. The unhandled exception could cause excessive resource consumption on the application server and/or its logging facilities. This vulnerability exists due to an incomplete fix for CVE-2023-47627. Version 3.9.2 fixes this vulnerability. | ||||
| CVE-2023-47641 | 1 Aiohttp | 1 Aiohttp | 2025-11-03 | 3.4 Low |
| aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Affected versions of aiohttp have a security vulnerability regarding the inconsistent interpretation of the http protocol. HTTP/1.1 is a persistent protocol, if both Content-Length(CL) and Transfer-Encoding(TE) header values are present it can lead to incorrect interpretation of two entities that parse the HTTP and we can poison other sockets with this incorrect interpretation. A possible Proof-of-Concept (POC) would be a configuration with a reverse proxy(frontend) that accepts both CL and TE headers and aiohttp as backend. As aiohttp parses anything with chunked, we can pass a chunked123 as TE, the frontend entity will ignore this header and will parse Content-Length. The impact of this vulnerability is that it is possible to bypass any proxy rule, poisoning sockets to other users like passing Authentication Headers, also if it is present an Open Redirect an attacker could combine it to redirect random users to another website and log the request. This vulnerability has been addressed in release 3.8.0 of aiohttp. Users are advised to upgrade. There are no known workarounds for this vulnerability. | ||||
| CVE-2023-47627 | 2 Aiohttp, Redhat | 5 Aiohttp, Ansible Automation Platform, Rhui and 2 more | 2025-11-03 | 5.3 Medium |
| aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. The HTTP parser in AIOHTTP has numerous problems with header parsing, which could lead to request smuggling. This parser is only used when AIOHTTP_NO_EXTENSIONS is enabled (or not using a prebuilt wheel). These bugs have been addressed in commit `d5c12ba89` which has been included in release version 3.8.6. Users are advised to upgrade. There are no known workarounds for these issues. | ||||
