| CVE-2025-31137 | 2026-04-15 | N/A | 7.5 HIGH | ||
| React Router is a multi-strategy router for React bridging the gap from React 18 to React 19. There is a vulnerability in Remix/React Router that affects all Remix 2 and React Router 7 consumers using the Express adapter. Basically, this vulnerability allows anyone to spoof the URL used in an incoming Request by putting a URL pathname in the port section of a URL that is part of a Host or X-Forwarded-Host header sent to a Remix/React Router request handler. This issue has been patched and released in Remix 2.16.3 and React Router 7.4.1. | |||||
| CVE-2024-27982 | 2026-04-15 | N/A | 6.5 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-2023-53878 | 2026-04-15 | N/A | N/A | ||
| Member Login Script 3.3 contains a client-side desynchronization vulnerability that allows attackers to manipulate HTTP request handling by exploiting Content-Length header parsing. Attackers can send crafted POST requests with smuggled secondary requests to potentially bypass server-side request processing controls. | |||||
| CVE-2025-41235 | 2026-04-15 | N/A | 8.6 HIGH | ||
| Spring Cloud Gateway Server forwards the X-Forwarded-For and Forwarded headers from untrusted proxies. | |||||
| CVE-2024-9622 | 2026-04-15 | N/A | 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-2025-14523 | 2026-04-15 | N/A | 8.2 HIGH | ||
| A flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend interprets it as destined for another host. This discrepancy enables request-smuggling style attacks, cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers. | |||||
| CVE-2026-26365 | 2026-04-15 | N/A | 4.0 MEDIUM | ||
| Akamai Ghost on Akamai CDN edge servers before 2026-02-06 mishandles processing of custom hop-by-hop HTTP headers, where an incoming request containing the header "Connection: Transfer-Encoding" could result in a forward request with invalid message framing, depending on the Akamai processing path. This could result in the origin server parsing the request body incorrectly, leading to HTTP request smuggling. | |||||
| CVE-2026-24880 | 1 Apache | 1 Tomcat | 2026-04-14 | N/A | 7.5 HIGH |
| Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in Apache Tomcat via invalid chunk extension. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.18, from 10.1.0-M1 through 10.1.52, from 9.0.0.M1 through 9.0.115, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109.

| CVE-2024-44775 | 1 Davidepianca98 | 1 Kmqtt | 2026-04-03 | N/A | 7.5 HIGH |
| kmqtt v0.2.7 is vulnerable to Denial of Service (DoS) due to a Null Pointer Exception. A remote attacker can cause the broker to crash by sending a specially crafted MQTT CONNECT packet that triggers an unhandled null reference, leading to an immediate process termination. | |||||
| CVE-2026-34441 | 1 Yhirose | 1 Cpp-httplib | 2026-04-01 | N/A | 4.8 MEDIUM |
| cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to version 0.40.0, cpp-httplib is vulnerable to HTTP Request Smuggling. The server's static file handler serves GET responses without consuming the request body. On HTTP/1.1 keep-alive connections, the unread body bytes remain on the TCP stream and are interpreted as the start of a new HTTP request. An attacker can embed an arbitrary HTTP request inside the body of a GET request, which the server processes as a separate request. This issue has been patched in version 0.40.0. | |||||
| CVE-2026-28368 | 1 Redhat | 10 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Data Grid and 7 more | 2026-03-31 | N/A | 8.7 HIGH |
| A flaw was found in Undertow. This vulnerability allows a remote attacker to construct specially crafted requests where header names are parsed differently by Undertow compared to upstream proxies. This discrepancy in header interpretation can be exploited to launch request smuggling attacks, potentially bypassing security controls and accessing unauthorized resources. | |||||
| CVE-2026-28369 | 1 Redhat | 10 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Data Grid and 7 more | 2026-03-31 | N/A | 8.7 HIGH |
| A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted information, or manipulate web caches, potentially leading to unauthorized actions or data exposure. | |||||
| CVE-2026-33870 | 1 Netty | 1 Netty | 2026-03-30 | N/A | 7.5 HIGH |
| Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.132.Final and 4.2.10.Final, Netty incorrectly parses quoted strings in HTTP/1.1 chunked transfer encoding extension values, enabling request smuggling attacks. Versions 4.1.132.Final and 4.2.10.Final fix the issue. | |||||
| CVE-2026-1801 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-03-26 | N/A | 5.3 MEDIUM |
| A flaw was found in libsoup, an HTTP client/server library. This HTTP Request Smuggling vulnerability arises from non-RFC-compliant parsing in the soup_filter_input_stream_read_line() logic, where libsoup accepts malformed chunk headers, such as lone line feed (LF) characters instead of the required carriage return and line feed (CRLF). A remote attacker can exploit this without authentication or user interaction by sending specially crafted chunked requests. This allows libsoup to parse and process multiple HTTP requests from a single network message, potentially leading to information disclosure. | |||||
| CVE-2026-1525 | 1 Nodejs | 1 Undici | 2026-03-19 | N/A | 6.5 MEDIUM |
| Undici allows duplicate HTTP Content-Length headers when they are provided in an array with case-variant names (e.g., Content-Length and content-length). This produces malformed HTTP/1.1 requests with multiple conflicting Content-Length values on the wire. Who is impacted: * Applications using undici.request(), undici.Client, or similar low-level APIs with headers passed as flat arrays * Applications that accept user-controlled header names without case-normalization Potential consequences: * Denial of Service: Strict HTTP parsers (proxies, servers) will reject requests with duplicate Content-Length headers (400 Bad Request) * HTTP Request Smuggling: In deployments where an intermediary and backend interpret duplicate headers inconsistently (e.g., one uses the first value, the other uses the last), this can enable request smuggling attacks leading to ACL bypass, cache poisoning, or credential hijacking | |||||
