| CVE-2025-0604 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-04-15 | 5.4 Medium |
| A flaw was found in Keycloak. When an Active Directory user resets their password, the system updates it without performing an LDAP bind to validate the new credentials against AD. This vulnerability allows users whose AD accounts are expired or disabled to regain access in Keycloak, bypassing AD restrictions. The issue enables authentication bypass and could allow unauthorized access under certain conditions. | ||||
| CVE-2024-5967 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Rhosemc | 2026-04-15 | 2.7 Low |
| A vulnerability was found in Keycloak. The LDAP testing endpoint allows changing the Connection URL independently without re-entering the currently configured LDAP bind credentials. This flaw allows an attacker with admin access (permission manage-realm) to change the LDAP host URL ("Connection URL") to a machine they control. The Keycloak server will connect to the attacker's host and try to authenticate with the configured credentials, thus leaking them to the attacker. As a consequence, an attacker who has compromised the admin console or compromised a user with sufficient privileges can leak domain credentials and attack the domain. | ||||
| CVE-2024-6162 | 1 Redhat | 11 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 8 more | 2026-04-15 | 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-2025-11429 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 5.4 Medium |
| A flaw was found in Keycloak. Keycloak does not immediately enforce the disabling of the "Remember Me" realm setting on existing user sessions. Sessions created while "Remember Me" was active retain their extended session lifetime until they expire, overriding the administrator's recent security configuration change. This is a logic flaw in session management increases the potential window for successful session hijacking or unauthorized long-term access persistence. The flaw lies in the session expiration logic relying on the session-local "remember-me" flag without validating the current realm-level configuration. | ||||
| 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-2025-12390 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 6 Medium |
| A flaw was found in Keycloak. In Keycloak where a user can accidentally get access to another user's session if both use the same device and browser. This happens because Keycloak sometimes reuses session identifiers and doesn’t clean up properly during logout when browser cookies are missing. As a result, one user may receive tokens that belong to another user. | ||||
| CVE-2025-11538 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 6.8 Medium |
| A vulnerability exists in Keycloak's server distribution where enabling debug mode (--debug <port>) insecurely defaults to binding the Java Debug Wire Protocol (JDWP) port to all network interfaces (0.0.0.0). This exposes the debug port to the local network, allowing an attacker on the same network segment to attach a remote debugger and achieve remote code execution within the Keycloak Java virtual machine. | ||||
| 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-2023-0657 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-04-15 | 3.4 Low |
| A flaw was found in Keycloak. This issue occurs due to improperly enforcing token types when validating signatures locally. This could allow an authenticated attacker to exchange a logout token for an access token and possibly gain access to data outside of enforced permissions. | ||||
| CVE-2025-13881 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 2.7 Low |
| A flaw was found in Keycloak Admin API. This vulnerability allows an administrator with limited privileges to retrieve sensitive custom attributes via the /unmanagedAttributes endpoint, bypassing User Profile visibility settings. | ||||
| CVE-2024-10451 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On | 2026-04-15 | 5.9 Medium |
| A flaw was found in Keycloak. This issue occurs because sensitive runtime values, such as passwords, may be captured during the Keycloak build process and embedded as default values in bytecode, leading to unintended information disclosure. In Keycloak 26, sensitive data specified directly in environment variables during the build process is also stored as a default values, making it accessible during runtime. Indirect usage of environment variables for SPI options and Quarkus properties is also vulnerable due to unconditional expansion by PropertyMapper logic, capturing sensitive data as default values in all Keycloak versions up to 26.0.2. | ||||
| 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-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. | ||||
| CVE-2025-12150 | 1 Redhat | 3 Build Keycloak, Build Of Keycloak, Keycloak | 2026-03-06 | 3.1 Low |
| A flaw was found in Keycloak’s WebAuthn registration component. This vulnerability allows an attacker to bypass the configured attestation policy and register untrusted or forged authenticators via submission of an attestation object with fmt: "none", even when the realm is configured to require direct attestation. This can lead to weakened authentication integrity and unauthorized authenticator registration. | ||||
| CVE-2023-6134 | 1 Redhat | 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more | 2026-02-25 | 4.6 Medium |
| A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748. | ||||
