CVE-2024-8925 1 Php 1 Php 2025-08-19 N/A 5.3 MEDIUM
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-2025-6442 1 Ruby-lang 1 Webrick 2025-08-18 N/A 5.9 MEDIUM
Ruby WEBrick read_header HTTP Request Smuggling Vulnerability. This vulnerability allows remote attackers to smuggle arbitrary HTTP requests on affected installations of Ruby WEBrick. This issue is exploitable when the product is deployed behind an HTTP proxy that fulfills specific conditions. The specific flaw exists within the read_headers method. The issue results from the inconsistent parsing of terminators of HTTP headers. An attacker can leverage this vulnerability to smuggle arbitrary HTTP requests. Was ZDI-CAN-21876.
CVE-2025-53643 1 Aiohttp 1 Aiohttp 2025-08-14 N/A 7.5 HIGH
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. 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 3.12.14 contains a patch for this issue.
CVE-2023-46589 1 Apache 1 Tomcat 2025-08-07 N/A 7.5 HIGH
Improper Input Validation vulnerability in Apache Tomcat.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 did not correctly parse HTTP trailer headers. A trailer header that exceeded the header size limit could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. Older, EOL versions may also be affected. Users are recommended to upgrade to version 11.0.0-M11 onwards, 10.1.16 onwards, 9.0.83 onwards or 8.5.96 onwards, which fix the issue.
CVE-2025-32094 2025-08-07 N/A N/A
An issue was discovered in Akamai Ghost, as used for the Akamai CDN platform before 2025-03-26. Under certain circumstances, a client making an HTTP/1.x OPTIONS request with an "Expect: 100-continue" header, and using obsolete line folding, can lead to a discrepancy in how two in-path Akamai servers interpret the request, allowing an attacker to smuggle a second request in the original request body.
CVE-2025-53628 1 Yhirose 1 Cpp-httplib 2025-08-06 N/A 8.8 HIGH
cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.20.1, cpp-httplib does not have a limit for a unique line, permitting an attacker to explore this to allocate memory arbitrarily. This vulnerability is fixed in 0.20.1. NOTE: This vulnerability is related to CVE-2025-53629.
CVE-2025-52892 2025-08-05 N/A N/A
EspoCRM is a web application with a frontend designed as a single-page application and a REST API backend written in PHP. In versions 9.1.6 and below, if a user loads Espo in the browser with double slashes (e.g https://domain//#Admin) and the webserver does not strip the double slash, it can cause a corrupted Slim router's cache. This will make the instance unusable until there is a completed rebuild. This is fixed in version 9.1.7.
CVE-2024-10264 1 Youdao 1 Qanything 2025-08-01 N/A 9.8 CRITICAL
HTTP Request Smuggling vulnerability in netease-youdao/qanything version 1.4.1 allows attackers to exploit inconsistencies in the interpretation of HTTP requests between a proxy and a server. This can lead to unauthorized access, bypassing security controls, session hijacking, data leakage, and potentially arbitrary code execution.
CVE-2019-16869 4 Canonical, Debian, Netty and 1 more 5 Ubuntu Linux, Debian Linux, Netty and 2 more 2025-07-07 5.0 MEDIUM 7.5 HIGH
Netty before 4.1.42.Final mishandles whitespace before the colon in HTTP headers (such as a "Transfer-Encoding : chunked" line), which leads to HTTP request smuggling.
CVE-2022-39163 2 Ibm, Microsoft 3 Cognos Controller, Controller, Windows 2025-07-03 N/A 4.7 MEDIUM
IBM Cognos Controller 11.0.0 through 11.1.0 is vulnerable to a Client-Side Desync (CSD) attack where an attacker could exploit a desynchronized browser connection that could lead to further cross-site scripting (XSS) attacks.
CVE-2019-20444 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2025-07-01 6.4 MEDIUM 9.1 CRITICAL
HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an "invalid fold."
CVE-2023-52354 1 Blitiri 1 Chasquid 2025-06-17 N/A 7.5 HIGH
chasquid before 1.13 allows SMTP smuggling because LF-terminated lines are accepted.
CVE-2022-42252 1 Apache 1 Tomcat 2025-05-06 N/A 7.5 HIGH
If Apache Tomcat 8.5.0 to 8.5.82, 9.0.0-M1 to 9.0.67, 10.0.0-M1 to 10.0.26 or 10.1.0-M1 to 10.1.0 was configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (the default for 8.5.x only), Tomcat did not reject a request containing an invalid Content-Length header making a request smuggling attack possible if Tomcat was located behind a reverse proxy that also failed to reject the request with the invalid header.
CVE-2020-11993 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2025-05-01 4.3 MEDIUM 7.5 HIGH
Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.
CVE-2022-26377 3 Apache, Fedoraproject, Netapp 3 Http Server, Fedora, Clustered Data Ontap 2025-05-01 5.0 MEDIUM 7.5 HIGH
Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.
CVE-2023-27522 3 Apache, Debian, Unbit 3 Http Server, Debian Linux, Uwsgi 2025-05-01 N/A 7.5 HIGH
HTTP Response Smuggling vulnerability in Apache HTTP Server via mod_proxy_uwsgi. This issue affects Apache HTTP Server: from 2.4.30 through 2.4.55. Special characters in the origin response header can truncate/split the response forwarded to the client.
CVE-2022-45059 2 Fedoraproject, Varnish Cache Project 2 Fedora, Varnish Cache 2025-05-01 N/A 7.5 HIGH
An issue was discovered in Varnish Cache 7.x before 7.1.2 and 7.2.x before 7.2.1. A request smuggling attack can be performed on Varnish Cache servers by requesting that certain headers are made hop-by-hop, preventing the Varnish Cache servers from forwarding critical headers to the backend.
CVE-2025-43859 2025-04-24 N/A N/A
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-2022-35256 4 Debian, Llhttp, Nodejs and 1 more 4 Debian Linux, Llhttp, Node.js and 1 more 2025-04-24 N/A 6.5 MEDIUM
The llhttp parser in the http module in Node v18.7.0 does not correctly handle header fields that are not terminated with CLRF. This may result in HTTP Request Smuggling.
CVE-2022-36760 1 Apache 1 Http Server 2025-04-04 N/A 9.0 CRITICAL
Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.
