CVE-2024-4028 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2026-04-15 3.8 Low
A vulnerability was found in Keycloak. This issue may allow a privileged attacker to use a malicious payload as the permission while creating items (Resource and Permissions) from the admin console, leading to a stored cross-site scripting (XSS) attack.
CVE-2024-3653 1 Redhat 17 Amq Streams, Apache Camel Hawtio, Build Keycloak and 14 more 2026-04-15 5.3 Medium
A vulnerability was found in Undertow. This issue requires enabling the learning-push handler in the server's config, which is disabled by default, leaving the maxAge config in the handler unconfigured. The default is -1, which makes the handler vulnerable. If someone overwrites that config, the server is not subject to the attack. The attacker needs to be able to reach the server with a normal HTTP request.
CVE-2023-6544 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2026-04-15 5.4 Medium
A flaw was found in the Keycloak package. This issue occurs due to a permissive regular expression hardcoded for filtering which allows hosts to register a dynamic client. A malicious user with enough information about the environment could jeopardize an environment with this specific Dynamic Client Registration and TrustedDomain configuration previously unauthorized.
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-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-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-2023-3597 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2026-04-15 5 Medium
A flaw was found in Keycloak, where it does not correctly validate its client step-up authentication in org.keycloak.authentication. This flaw allows a remote user authenticated with a password to register a false second authentication factor along with an existing one and bypass authentication.
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-2025-9162 1 Redhat 1 Build Keycloak 2026-04-15 4.9 Medium
A flaw was found in org.keycloak/keycloak-model-storage-service. The KeycloakRealmImport custom resource substitutes placeholders within imported realm documents, potentially referencing environment variables. This substitution process allows for injection attacks when crafted realm documents are processed. An attacker can leverage this to inject malicious content during the realm import procedure. This can lead to unintended consequences within the Keycloak environment.
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-2024-10973 1 Redhat 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp 2026-04-15 5.7 Medium
A vulnerability was found in Keycloak. The environment option `KC_CACHE_EMBEDDED_MTLS_ENABLED` does not work and the JGroups replication configuration is always used in plain text which can allow an attacker that has access to adjacent networks related to JGroups to read sensitive information.
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-2024-1249 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-2023-6717 1 Redhat 15 Amq Broker, Build Keycloak, Jboss Data Grid and 12 more 2026-04-15 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-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-2025-11538 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-2024-7341 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.
