A vulnerability was found in Wildfly’s management interface. Due to the lack of limitation of sockets for the management interface, it may be possible to cause a denial of service hitting the nofile limit as there is no possibility to configure or set a maximum number of connections.
CVE-2024-1102 2 Jberet, Redhat 7 Jberet, Build Keycloak, Jboss Data Grid and 4 more 2025-08-14 6.5 Medium
A vulnerability was found in jberet-core logging. An exception in 'dbProperties' might display user credentials such as the username and password for the database-connection.
CVE-2024-6162 1 Redhat 11 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 8 more 2025-08-14 7.5 High
A vulnerability was found in Undertow, where URL-encoded request paths can be mishandled during concurrent requests on the AJP listener. This issue arises because the same buffer is used to decode the paths for multiple requests simultaneously, leading to incorrect path information being processed. As a result, the server may attempt to access the wrong path, causing errors such as "404 Not Found" or other application failures. This flaw can potentially lead to a denial of service, as legitimate resources become inaccessible due to the path mix-up.
CVE-2024-1635 2 Netapp, Redhat 26 Active Iq Unified Manager, Oncommand Workflow Automation, Amq Streams and 23 more 2025-08-14 7.5 High
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-2024-7885 1 Redhat 20 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 17 more 2025-08-14 7.5 High
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-2024-5971 1 Redhat 12 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 9 more 2025-08-14 7.5 High
A vulnerability was found in Undertow, where the chunked response hangs after the body was flushed. The response headers and body were sent but the client would continue waiting as Undertow does not send the expected 0\r\n termination of the chunked response. This results in uncontrolled resource consumption, leaving the server side to a denial of service attack. This happens only with Java 17 TLSv1.3 scenarios.
CVE-2023-5685 1 Redhat 12 Apache-camel-spring-boot, Apache Camel Hawtio, Build Keycloak and 9 more 2025-08-14 7.5 High
A flaw was found in XNIO. The XNIO NotifierState that can cause a Stack Overflow Exception when the chain of notifier states becomes problematically large can lead to uncontrolled resource management and a possible denial of service (DoS).
CVE-2023-6717 1 Redhat 15 Amq Broker, Build Keycloak, Jboss Data Grid and 12 more 2025-08-14 6 Medium
A flaw was found in the SAML client registration in Keycloak that could allow an administrator to register malicious JavaScript URIs as Assertion Consumer Service POST Binding URLs (ACS), posing a Cross-Site Scripting (XSS) risk. This issue may allow a malicious admin in one realm or a client with registration access to target users in different realms or applications, executing arbitrary JavaScript in their contexts upon form submission. This can enable unauthorized access and harmful actions, compromising the confidentiality, integrity, and availability of the complete KC instance.
CVE-2025-8419 1 Redhat 2 Build Keycloak, Keycloak 2025-08-13 6.5 Medium
A vulnerability was found in Keycloak-services. Special characters used during e-mail registration may perform SMTP Injection and unexpectedly send short unwanted e-mails. The email is limited to 64 characters (limited local part of the email), so the attack is limited to very shorts emails (subject and little data, the example is 60 chars). This flaw's only direct consequence is an unsolicited email being sent from the Keycloak server. However, this action could be a precursor for more sophisticated attacks.
CVE-2025-5416 1 Redhat 2 Build Keycloak, Keycloak 2025-08-13 2.7 Low
A vulnerability has been identified in Keycloak that could lead to unauthorized information disclosure. While it requires an already authenticated user, the /admin/serverinfo endpoint can inadvertently provide sensitive environment information.
CVE-2024-1300 1 Redhat 20 A Mq Clients, Amq Broker, Amq Streams and 17 more 2025-08-12 5.4 Medium
A vulnerability in the Eclipse Vert.x toolkit causes a memory leak in TCP servers configured with TLS and SNI support. When processing an unknown SNI server name assigned the default certificate instead of a mapped certificate, the SSL context is erroneously cached in the server name map, leading to memory exhaustion. This flaw allows attackers to send TLS client hello messages with fake server names, triggering a JVM out-of-memory error.
CVE-2024-1023 1 Redhat 20 A Mq Clients, Amq Broker, Amq Streams and 17 more 2025-08-12 6.5 Medium
A vulnerability in the Eclipse Vert.x toolkit results in a memory leak due to using Netty FastThreadLocal data structures. Specifically, when the Vert.x HTTP client establishes connections to different hosts, triggering the memory leak. The leak can be accelerated with intimate runtime knowledge, allowing an attacker to exploit this vulnerability. For instance, a server accepting arbitrary internet addresses could serve as an attack vector by connecting to these addresses, thereby accelerating the memory leak.
CVE-2025-23368 1 Redhat 8 Build Keycloak, Integration, Jboss Data Grid and 5 more 2025-08-12 8.1 High
A flaw was found in Wildfly Elytron integration. The component does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks via CLI.
CVE-2025-7784 1 Redhat 5 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 2 more 2025-08-11 6.5 Medium
A flaw was found in the Keycloak identity and access management system when Fine-Grained Admin Permissions(FGAPv2) are enabled. An administrative user with the manage-users role can escalate their privileges to realm-admin due to improper privilege enforcement. This vulnerability allows unauthorized elevation of access rights, compromising the intended separation of administrative duties and posing a security risk to the realm.
CVE-2025-3501 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-08-07 8.2 High
A flaw was found in Keycloak. By setting a verification policy to 'ALL', the trust store certificate verification is skipped, which is unintended.
CVE-2023-6484 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2025-08-07 5.3 Medium
A log injection flaw was found in Keycloak. A text string may be injected through the authentication form when using the WebAuthn authentication mode. This issue may have a minor impact to the logs integrity.
CVE-2024-1249 1 Redhat 15 Amq Broker, Amq Streams, Build Keycloak and 12 more 2025-08-07 7.4 High
A flaw was found in Keycloak's OIDC component in the "checkLoginIframe," which allows unvalidated cross-origin messages. This flaw allows attackers to coordinate and send millions of requests in seconds using simple code, significantly impacting the application's availability without proper origin validation for incoming messages.
CVE-2024-1132 1 Redhat 23 Amq Broker, Build Keycloak, Build Of Keycloak and 20 more 2025-08-07 8.1 High
A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. This issue could allow an attacker to construct a malicious request to bypass validation and access other URLs and sensitive information within the domain or conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field, and requires user interaction within the malicious URL.
CVE-2023-6291 1 Redhat 18 Build Keycloak, Enterprise Linux, Jboss Data Grid and 15 more 2025-08-07 7.1 High
A flaw was found in the redirect_uri validation logic in Keycloak. This issue may allow a bypass of otherwise explicitly allowed hosts. A successful attack may lead to an access token being stolen, making it possible for the attacker to impersonate other users.
CVE-2024-4540 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2025-08-07 7.5 High
A flaw was found in Keycloak in OAuth 2.0 Pushed Authorization Requests (PAR). Client-provided parameters were found to be included in plain text in the KC_RESTART cookie returned by the authorization server's HTTP response to a `request_uri` authorization request, possibly leading to an information disclosure vulnerability.
