| Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in Quest Coexistence Manager for Notes (Free/Busy Connector modules) allows HTTP Request Smuggling via the Content-Length-Transfer-Encoding (CL.TE) attack vector. This could allow an attacker to bypass access controls, poison web caches, hijack sessions, or trigger unintended internal requests. This issue affects Coexistence Manager for Notes 3.8.2045. Other versions may also be affected. |
| 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. |
| 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. |
| 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. |
| Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') vulnerability in ithewei libhv allows HTTP Response Smuggling.This issue affects libhv: through 1.3.3. |
| 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. |
| HTTP request desynchronization in Ping Identity PingAccess, all versions prior to 8.0.1 affected allows an attacker to send specially crafted http header requests to create a request smuggling condition for proxied requests. |
| 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. |
| 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. |
| A vulnerability classified as critical was found in mhuertos phpLDAPadmin up to 665dbc2690ebeb5392d38f1fece0a654225a0b38. Affected by this vulnerability is the function makeHttpRequest of the file htdocs/js/ajax_functions.js. The manipulation leads to http request smuggling. The attack can be launched remotely. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The patch is named dd6e9583a2eb2ca085583765e8a63df5904cb036. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-270523. |
| 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) |
| Spring Cloud Gateway Server forwards the X-Forwarded-For and Forwarded headers from untrusted proxies. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
