| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| CVE-2026-41731 | High | 2026-06-10 | No exploit published | No public exploit | JsonKafkaHeaderMapper and the deprecated DefaultKafkaHeaderMapper matched type headers against trusted packages using a prefix check, meaning that trusting any package implicitly trusted all of its subpackages. Combined with Jackson's default bean deserialization, a producer could supply crafted header values that caused the consumer to deserialize arbitrary JDK types. Affected versions: Spring for Apache Kafka 4.0.0 through 4.0.5; 3.3.0 through 3.3.15; 3.2.0 through 3.2.13; 2.9.0 through 2.9.13; 2.8.0 through 2.8.11. |
| CVE-2025-9784 | High | 2025-09-02 | No exploit published | No public exploit | A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS). |
| CVE-2024-7885 | High | 2024-08-21 | No exploit published | No public exploit | A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments. |
| CVE-2024-1635 | High | 2024-02-19 | No exploit published | No public exploit | A vulnerability was found in Undertow. This vulnerability impacts a server that supports the wildfly-http-client protocol. Whenever a malicious user opens and closes a connection with the HTTP port of the server and then closes the connection immediately, the server will end with both memory and open file limits exhausted at some point, depending on the amount of memory available. At HTTP upgrade to remoting, the WriteTimeoutStreamSinkConduit leaks connections if RemotingConnection is closed by Remoting ServerConnectionOpenListener. Because the remoting connection originates in Undertow as part of the HTTP upgrade, there is an external layer to the remoting connection. This connection is unaware of the outermost layer when closing the connection during the connection opening procedure. Hence, the Undertow WriteTimeoutStreamSinkConduit is not notified of the closed connection in this scenario. Because WriteTimeoutStreamSinkConduit creates a timeout task, the whole dependency tree leaks via that task, which is added to XNIO WorkerThread. So, the workerThread points to the Undertow conduit, which contains the connections and causes the leak. |
| CVE-2023-1108 | High | 2023-09-14 | No exploit published | No public exploit | A flaw was found in undertow. This issue makes achieving a denial of service possible due to an unexpected handshake status updated in SslConduit, where the loop never terminates. |
| CVE-2022-4492 | High | 2023-02-23 | No exploit published | No public exploit | The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol. |
| CVE-2021-3690 | High | 2022-08-23 | No exploit published | No public exploit | A flaw was found in Undertow. A buffer leak on the incoming WebSocket PONG message may lead to memory exhaustion. This flaw allows an attacker to cause a denial of service. The highest threat from this vulnerability is availability. |
| CVE-2022-2053 | High | 2022-08-05 | No exploit published | No public exploit | When a POST request comes through AJP and the request exceeds the max-post-size limit (maxEntitySize), Undertow's AjpServerRequestConduit implementation closes a connection without sending any response to the client/proxy. This behavior results in that a front-end proxy marking the backend worker (application server) as an error state and not forward requests to the worker for a while. In mod_cluster, this continues until the next STATUS request (10 seconds intervals) from the application server updates the server state. So, in the worst case, it can result in "All workers are in error state" and mod_cluster responds "503 Service Unavailable" for a while (up to 10 seconds). In mod_proxy_balancer, it does not forward requests to the worker until the "retry" timeout passes. However, luckily, mod_proxy_balancer has "forcerecovery" setting (On by default; this parameter can force the immediate recovery of all workers without considering the retry parameter of the workers if all workers of a balancer are in error state.). So, unlike mod_cluster, mod_proxy_balancer does not result in responding "503 Service Unavailable". An attacker could use this behavior to send a malicious request and trigger server errors, resulting in DoS (denial of service). This flaw was fixed in Undertow 2.2.19.Final, Undertow 2.3.0.Alpha2. |
| CVE-2020-27782 | High | 2021-02-23 | No exploit published | No public exploit | A flaw was found in the Undertow AJP connector. Malicious requests and abrupt connection closes could be triggered by an attacker using query strings with non-RFC compliant characters resulting in a denial of service. The highest threat from this vulnerability is to system availability. This affects Undertow 2.1.5.SP1, 2.0.33.SP2, and 2.2.3.SP1. |
| CVE-2020-10714 | High | 2020-09-23 | No exploit published | No public exploit | A flaw was found in WildFly Elytron version 1.11.3.Final and before. When using WildFly Elytron FORM authentication with a session ID in the URL, an attacker could perform a session fixation attack. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. |
| CVE-2020-10718 | High | 2020-09-16 | No exploit published | No public exploit | A flaw was found in Wildfly before wildfly-embedded-13.0.0.Final, where the embedded managed process API has an exposed setting of the Thread Context Classloader (TCCL). This setting is exposed as a public method, which can bypass the security manager. The highest threat from this vulnerability is to confidentiality. |
| CVE-2020-1718 | High | 2020-05-12 | No exploit published | No public exploit | A flaw was found in the reset credential flow in all Keycloak versions before 8.0.0. This flaw allows an attacker to gain unauthorized access to the application. |
| CVE-2020-1757 | High | 2020-04-21 | No exploit published | No public exploit | A flaw was found in all undertow-2.x.x SP1 versions prior to undertow-2.0.30.SP1, all undertow-1.x.x and undertow-2.x.x versions prior to undertow-2.1.0.Final, where the Servlet container causes servletPath to normalize incorrectly by truncating the path after semicolon which may lead to an application mapping resulting in the security bypass. |
| CVE-2019-14888 | High | 2020-01-23 | No exploit published | No public exploit | A vulnerability was found in the Undertow HTTP server in versions before 2.0.28.SP1 when listening on HTTPS. An attacker can target the HTTPS port to carry out a Denial Of Service (DOS) to make the service unavailable on SSL. |
| CVE-2018-1258 | High | 2018-05-11 | No exploit published | No public exploit | Spring Framework version 5.0.5 when used in combination with any versions of Spring Security contains an authorization bypass when using method security. An unauthorized malicious user can gain unauthorized access to methods that should be restricted. |
| CVE-2014-0120 | High | 2017-12-29 | No exploit published | No public exploit | Cross-site request forgery (CSRF) vulnerability in the admin terminal in Hawt.io allows remote attackers to hijack the authentication of arbitrary users for requests that run commands on the Karaf server, as demonstrated by running "shutdown -f." |
| CVE-2017-7957 | High | 2017-04-29 | No exploit published | No public exploit | XStream through 1.4.9, when a certain denyTypes workaround is not used, mishandles attempts to create an instance of the primitive type 'void' during unmarshalling, leading to a remote application crash, as demonstrated by an xstream.fromXML("<void/>") call. |
