| The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly parse and validate Transfer-Encoding headers and can lead to HTTP Request Smuggling (HRS). | ||||
| CVE-2022-32214 | 5 Debian, Llhttp, Nodejs and 2 more | 7 Debian Linux, Llhttp, Node.js and 4 more | 2025-04-30 | 6.5 Medium |
| The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS). | ||||
| CVE-2022-32215 | 7 Debian, Fedoraproject, Llhttp and 4 more | 9 Debian Linux, Fedora, Llhttp and 6 more | 2025-04-30 | 6.5 Medium |
| The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly handle multi-line Transfer-Encoding headers. This can lead to HTTP Request Smuggling (HRS). | ||||
| CVE-2021-22960 | 4 Debian, Llhttp, Oracle and 1 more | 7 Debian Linux, Llhttp, Graalvm and 4 more | 2025-04-30 | 6.5 Medium |
| The parse function in llhttp < 2.1.4 and < 6.0.6. ignores chunk extensions when parsing the body of chunked requests. This leads to HTTP Request Smuggling (HRS) under certain conditions. | ||||
| 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 |
| HTTP request smuggling in Node.js 10, 12, and 13 causes malicious payload delivery when transfer-encoding is malformed | ||||
| CVE-2024-53868 | 1 Apache | 1 Traffic Server | 2025-04-29 | 7.5 High |
| Apache Traffic Server allows request smuggling if chunked messages are malformed. This issue affects Apache Traffic Server: from 9.2.0 through 9.2.9, from 10.0.0 through 10.0.4. Users are recommended to upgrade to version 9.2.10 or 10.0.5, which fixes the issue. | ||||
| CVE-2025-43859 | 2025-04-29 | 9.1 Critical | ||
| h11 is a Python implementation of HTTP/1.1. Prior to version 0.16.0, a leniency in h11's parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions. This issue has been patched in version 0.16.0. Since exploitation requires the combination of buggy h11 with a buggy (reverse) proxy, fixing either component is sufficient to mitigate this issue. | ||||
| CVE-2024-35538 | 1 Typecho | 1 Typecho | 2025-04-28 | 5.3 Medium |
| Typecho v1.3.0 was discovered to contain a Client IP Spoofing vulnerability, which allows attackers to falsify their IP addresses by specifying an arbitrary IP as value of X-Forwarded-For or Client-Ip headers while performing HTTP requests. | ||||
| CVE-2022-38114 | 1 Solarwinds | 1 Security Event Manager | 2025-04-25 | 6.1 Medium |
| This vulnerability occurs when a web server fails to correctly process the Content-Length of POST requests. This can lead to HTTP request smuggling or XSS. | ||||
| CVE-2022-24761 | 3 Agendaless, Debian, Redhat | 3 Waitress, Debian Linux, Openstack | 2025-04-23 | 7.5 High |
| Waitress is a Web Server Gateway Interface server for Python 2 and 3. When using Waitress versions 2.1.0 and prior behind a proxy that does not properly validate the incoming HTTP request matches the RFC7230 standard, Waitress and the frontend proxy may disagree on where one request starts and where it ends. This would allow requests to be smuggled via the front-end proxy to waitress and later behavior. There are two classes of vulnerability that may lead to request smuggling that are addressed by this advisory: The use of Python's `int()` to parse strings into integers, leading to `+10` to be parsed as `10`, or `0x01` to be parsed as `1`, where as the standard specifies that the string should contain only digits or hex digits; and Waitress does not support chunk extensions, however it was discarding them without validating that they did not contain illegal characters. This vulnerability has been patched in Waitress 2.1.1. A workaround is available. When deploying a proxy in front of waitress, turning on any and all functionality to make sure that the request matches the RFC7230 standard. Certain proxy servers may not have this functionality though and users are encouraged to upgrade to the latest version of waitress instead. | ||||
| CVE-2022-24766 | 1 Mitmproxy | 1 Mitmproxy | 2025-04-23 | 9.8 Critical |
| mitmproxy is an interactive, SSL/TLS-capable intercepting proxy. In mitmproxy 7.0.4 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 mitmproxy would only see one request, the target server would see multiple requests. A smuggled request is still captured as part of another request's body, but 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 mitmproxy is used to protect an HTTP/1 service, no action is required. The vulnerability has been fixed in mitmproxy 8.0.0 and above. There are currently no known workarounds. | ||||
| CVE-2022-24790 | 4 Debian, Fedoraproject, Puma and 1 more | 5 Debian Linux, Fedora, Puma and 2 more | 2025-04-23 | 9.1 Critical |
| Puma is a simple, fast, multi-threaded, parallel HTTP 1.1 server for Ruby/Rack applications. When using Puma behind a proxy that does not properly validate that the incoming HTTP request matches the RFC7230 standard, Puma and the frontend proxy may disagree on where a request starts and ends. This would allow requests to be smuggled via the front-end proxy to Puma. The vulnerability has been fixed in 5.6.4 and 4.3.12. Users are advised to upgrade as soon as possible. Workaround: when deploying a proxy in front of Puma, turning on any and all functionality to make sure that the request matches the RFC7230 standard. | ||||
| CVE-2022-24801 | 5 Debian, Fedoraproject, Oracle and 2 more | 6 Debian Linux, Fedora, Zfs Storage Appliance Kit and 3 more | 2025-04-23 | 8.1 High |
| Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the `twisted.web.http` module, parsed several HTTP request constructs more leniently than permitted by RFC 7230. This non-conformant parsing can lead to desync if requests pass through multiple HTTP parsers, potentially resulting in HTTP request smuggling. Users who may be affected use Twisted Web's HTTP 1.1 server and/or proxy and also pass requests through a different HTTP server and/or proxy. The Twisted Web client is not affected. The HTTP 2.0 server uses a different parser, so it is not affected. The issue has been addressed in Twisted 22.4.0rc1. Two workarounds are available: Ensure any vulnerabilities in upstream proxies have been addressed, such as by upgrading them; or filter malformed requests by other means, such as configuration of an upstream proxy. | ||||
| CVE-2022-31109 | 1 Getlaminas | 1 Laminas-diactoros | 2025-04-23 | 7.2 High |
| laminas-diactoros is a PHP package containing implementations of the PSR-7 HTTP message interfaces and PSR-17 HTTP message factory interfaces. Applications that use Diactoros, and are either not behind a proxy, or can be accessed via untrusted proxies, can potentially have the host, protocol, and/or port of a `Laminas\Diactoros\Uri` instance associated with the incoming server request modified to reflect values from `X-Forwarded-*` headers. Such changes can potentially lead to XSS attacks (if a fully-qualified URL is used in links) and/or URL poisoning. Since the `X-Forwarded-*` headers do have valid use cases, particularly in clustered environments using a load balancer, the library offers mitigation measures only in the v2 releases, as doing otherwise would break these use cases immediately. Users of v2 releases from 2.11.1 can provide an additional argument to `Laminas\Diactoros\ServerRequestFactory::fromGlobals()` in the form of a `Laminas\Diactoros\RequestFilter\RequestFilterInterface` instance, including the shipped `Laminas\Diactoros\RequestFilter\NoOpRequestFilter` implementation which ignores the `X-Forwarded-*` headers. Starting in version 3.0, the library will reverse behavior to use the `NoOpRequestFilter` by default, and require users to opt-in to `X-Forwarded-*` header usage via a configured `Laminas\Diactoros\RequestFilter\LegacyXForwardedHeaderFilter` instance. Users are advised to upgrade to version 2.11.1 or later to resolve this issue. Users unable to upgrade may configure web servers to reject `X-Forwarded-*` headers at the web server level. | ||||
| CVE-2024-33452 | 2025-04-23 | 7.7 High | ||
| An issue in OpenResty lua-nginx-module v.0.10.26 and before allows a remote attacker to conduct HTTP request smuggling via a crafted HEAD request. | ||||
