CVE-2024-1135 2 Benoitc, Redhat 7 Gunicorn, Ansible Automation Platform, Openshift and 4 more 2026-04-15 N/A
Gunicorn fails to properly validate Transfer-Encoding headers, leading to HTTP Request Smuggling (HRS) vulnerabilities. By crafting requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue is due to Gunicorn's handling of Transfer-Encoding headers, where it incorrectly processes requests with multiple, conflicting Transfer-Encoding headers, treating them as chunked regardless of the final encoding specified. This vulnerability allows for a range of attacks including cache poisoning, session manipulation, and data exposure.
CVE-2024-41671 1 Twisted 1 Twisted 2026-04-15 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-2025-32094 1 Akamai 1 Ghost 2026-04-15 4 Medium
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-2023-4639 1 Redhat 14 Camel Quarkus, Camel Spring Boot, Integration and 11 more 2026-04-15 7.4 High
A flaw was found in Undertow, 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-2025-41235 2026-04-15 8.6 High
Spring Cloud Gateway Server forwards the X-Forwarded-For and Forwarded headers from untrusted proxies.
CVE-2025-12811 1 Delinea 1 Cloud Suite And Privileged Access Service 2026-04-15 N/A
Improper Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') in Delinea Inc. Cloud Suite and Privileged Access Service. If you're not using the latest Server Suite agents, this fix requires that you upgrade to Server Suite 2023.1 (agent 6.0.1) or later. * If you cannot upgrade to Release 2023.1 (agent version 6.0.1) or later, you can choose one of the following versions: * Server Suite release 2023.0.5 (agent version 6.0.0-158) * Server Suite release 2022.1.10 (agent version 5.9.1-337)
CVE-2025-14523 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-04-15 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-2024-38494 1 Broadcom 1 Symantec Privileged Access Management 2026-04-15 N/A
This vulnerability allows a high-privileged authenticated PAM user to achieve remote command execution on the affected PAM system by sending a specially crafted HTTP request.
CVE-2023-53878 1 Phpjabbers 1 Member Login Script 2026-04-15 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-2025-23167 1 Redhat 1 Enterprise Linux 2026-04-15 N/A
A flaw in Node.js 20's HTTP parser allows improper termination of HTTP/1 headers using `\r\n\rX` instead of the required `\r\n\r\n`. This inconsistency enables request smuggling, allowing attackers to bypass proxy-based access controls and submit unauthorized requests. The issue was resolved by upgrading `llhttp` to version 9, which enforces correct header termination. Impact: * This vulnerability affects only Node.js 20.x users prior to the `llhttp` v9 upgrade.
CVE-2025-6999 1 Watchguard 1 Fireware 2026-04-15 N/A
An HTTP Request Smuggling [CWE-444] vulnerability in the Authentication portal of WatchGuard Fireware OS allows a remote attacker to evade request parameter sanitation and perform a reflected self-Cross-Site Scripting (XSS) attack.This issue affects Fireware OS: from 12.0 through 12.11.2.
CVE-2024-9666 1 Redhat 2 Build Keycloak, Jboss Enterprise Application Platform 2026-04-15 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-2025-31137 2026-04-15 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-2025-11915 2 Google, Google Cloud 2 Cloud Platform, Vertex Ai 2026-04-15 N/A
Connection desynchronization between an HTTP proxy and the model backend. The fixes were rolled out for all proxies in front of impacted models by 2025-09-28. Users do not need to take any action.
CVE-2024-53008 1 Haproxy 1 Haproxy 2026-04-15 5.3 Medium
Inconsistent interpretation of HTTP requests ('HTTP Request/Response Smuggling') issue exists in HAProxy. If this vulnerability is exploited, a remote attacker may access a path that is restricted by ACL (Access Control List) set on the product. As a result, the attacker may obtain sensitive information.
CVE-2024-56908 2026-04-15 6.8 Medium
In Perfex Crm < 3.2.1, an authenticated attacker can send a crafted HTTP POST request to the affected upload_sales_file endpoint. By providing malicious input in the rel_id parameter, combined with improper input validation, the attacker can bypass restrictions and upload arbitrary files to directories of their choice, potentially leading to remote code execution or server compromise.
CVE-2024-9622 1 Redhat 3 Jboss Data Grid, Jboss Enterprise Application Platform, Jbosseapxp 2026-04-15 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-2024-41110 2 Docker, Redhat 2 Moby, Cert Manager 2026-04-15 10 Critical
Moby is an open-source project created by Docker for software containerization. A security vulnerability has been detected in certain versions of Docker Engine, which could allow an attacker to bypass authorization plugins (AuthZ) under specific circumstances. The base likelihood of this being exploited is low. Using a specially-crafted API request, an Engine API client could make the daemon forward the request or response to an authorization plugin without the body. In certain circumstances, the authorization plugin may allow a request which it would have otherwise denied if the body had been forwarded to it. A security issue was discovered In 2018, where an attacker could bypass AuthZ plugins using a specially crafted API request. This could lead to unauthorized actions, including privilege escalation. Although this issue was fixed in Docker Engine v18.09.1 in January 2019, the fix was not carried forward to later major versions, resulting in a regression. Anyone who depends on authorization plugins that introspect the request and/or response body to make access control decisions is potentially impacted. Docker EE v19.03.x and all versions of Mirantis Container Runtime are not vulnerable. docker-ce v27.1.1 containes patches to fix the vulnerability. Patches have also been merged into the master, 19.03, 20.0, 23.0, 24.0, 25.0, 26.0, and 26.1 release branches. If one is unable to upgrade immediately, avoid using AuthZ plugins and/or restrict access to the Docker API to trusted parties, following the principle of least privilege.
CVE-2025-22871 1 Redhat 13 Acm, Ansible Automation Platform, Cryostat and 10 more 2026-04-15 9.1 Critical
The net/http package improperly accepts a bare LF as a line terminator in chunked data chunk-size lines. This can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext.
CVE-2025-41082 1 Altitude 1 Communication Server 2026-04-15 N/A
Illegal HTTP request traffic vulnerability (CL.0) in Altitude Communication Server, caused by inconsistent analysis of multiple HTTP requests over a single Keep-Alive connection using Content-Length headers. This can cause a desynchronization of requests between frontend and backend servers, which could allow request hiding, cache poisoning or security bypass.
