| CVE-2025-12110 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 5.4 Medium |
| A flaw was found in Keycloak. An offline session continues to be valid when the offline_access scope is removed from the client. The refresh token is accepted and you can continue to request new tokens for the session. As it can lead to a situation where an administrator removes the scope, and assumes that offline sessions are no longer available, but they are. | ||||
| CVE-2024-2419 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 7.1 High |
| A flaw was found in Keycloak's redirect_uri validation logic. This issue may allow a bypass of otherwise explicitly allowed hosts. A successful attack may lead to the theft of an access token, making it possible for the attacker to impersonate other users. It is very similar to CVE-2023-6291. | ||||
| 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-2024-4029 | 1 Redhat | 7 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 4 more | 2026-04-15 | 4.1 Medium |
| 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-2025-14778 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-15 | 5.4 Medium |
| A flaw was found in Keycloak. A significant Broken Access Control vulnerability exists in the UserManagedPermissionService (UMA Protection API). When updating or deleting a UMA policy associated with multiple resources, the authorization check only verifies the caller's ownership against the first resource in the policy's list. This allows a user (Owner A) who owns one resource (RA) to update a shared policy and modify authorization rules for other resources (e.g., RB) in that same policy, even if those other resources are owned by a different user (Owner B). This constitutes a horizontal privilege escalation. | ||||
| CVE-2024-47072 | 2 Redhat, X-stream | 4 Build Keycloak, Jboss Data Grid, Ocp Tools and 1 more | 2026-04-15 | 7.5 High |
| XStream is a simple library to serialize objects to XML and back again. This vulnerability may allow a remote attacker to terminate the application with a stack overflow error resulting in a denial of service only by manipulating the processed input stream when XStream is configured to use the BinaryStreamDriver. XStream 1.4.21 has been patched to detect the manipulation in the binary input stream causing the the stack overflow and raises an InputManipulationException instead. Users are advised to upgrade. Users unable to upgrade may catch the StackOverflowError in the client code calling XStream if XStream is configured to use the BinaryStreamDriver. | ||||
| CVE-2023-5685 | 1 Redhat | 12 Apache-camel-spring-boot, Apache Camel Hawtio, Build Keycloak and 9 more | 2026-04-15 | 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-2024-5971 | 1 Redhat | 12 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 9 more | 2026-04-15 | 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-2025-14777 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 6 Medium |
| A flaw was found in Keycloak. An IDOR (Broken Access Control) vulnerability exists in the admin API endpoints for authorization resource management, specifically in ResourceSetService and PermissionTicketService. The system checks authorization against the resourceServer (client) ID provided in the API request, but the backend database lookup and modification operations (findById, delete) only use the resourceId. This mismatch allows an authenticated attacker with fine-grained admin permissions for one client (e.g., Client A) to delete or update resources belonging to another client (Client B) within the same realm by supplying a valid resource ID. | ||||
| CVE-2024-1023 | 1 Redhat | 20 A Mq Clients, Amq Broker, Amq Streams and 17 more | 2026-04-15 | 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-2024-8698 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On and 1 more | 2026-04-15 | 7.7 High |
| A flaw exists in the SAML signature validation method within the Keycloak XMLSignatureUtil class. The method incorrectly determines whether a SAML signature is for the full document or only for specific assertions based on the position of the signature in the XML document, rather than the Reference element used to specify the signed element. This flaw allows attackers to create crafted responses that can bypass the validation, potentially leading to privilege escalation or impersonation attacks. | ||||
| CVE-2024-1249 | 1 Redhat | 15 Amq Broker, Amq Streams, Build Keycloak and 12 more | 2026-04-15 | 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-2026-4628 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 5 more | 2026-04-02 | 4.3 Medium |
| A flaw was found in Keycloak. An improper Access Control vulnerability in Keycloak’s User-Managed Access (UMA) resource_set endpoint allows attackers with valid credentials to bypass the allowRemoteResourceManagement=false restriction. This occurs due to incomplete enforcement of access control checks on PUT operations to the resource_set endpoint. This issue enables unauthorized modification of protected resources, impacting data integrity. | ||||
| CVE-2026-4633 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-02 | 3.7 Low |
| A flaw was found in Keycloak. A remote attacker can exploit differential error messages during the identity-first login flow when Organizations are enabled. This vulnerability allows an attacker to determine the existence of users, leading to information disclosure through user enumeration. | ||||
| CVE-2025-23367 | 1 Redhat | 8 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 5 more | 2026-04-01 | 6.5 Medium |
| A flaw was found in the Wildfly Server Role Based Access Control (RBAC) provider. When authorization to control management operations is secured using the Role Based Access Control provider, a user without the required privileges can suspend or resume the server. A user with a Monitor or Auditor role is supposed to have only read access permissions and should not be able to suspend the server. The vulnerability is caused by the Suspend and Resume handlers not performing authorization checks to validate whether the current user has the required permissions to proceed with the action. | ||||
| CVE-2024-7341 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Enterprise Linux and 5 more | 2026-04-01 | 7.1 High |
| A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation. | ||||
| CVE-2024-8883 | 1 Redhat | 10 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 7 more | 2026-04-01 | 6.1 Medium |
| A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking. | ||||
| CVE-2024-4629 | 1 Redhat | 12 Build Keycloak, Build Of Keycloak, Enterprise Linux and 9 more | 2026-03-26 | 6.5 Medium |
| A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems. | ||||
| CVE-2024-1132 | 1 Redhat | 23 Amq Broker, Build Keycloak, Build Of Keycloak and 20 more | 2026-03-17 | 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-2024-1635 | 2 Netapp, Redhat | 26 Active Iq Unified Manager, Oncommand Workflow Automation, Amq Streams and 23 more | 2026-03-17 | 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. | ||||
