| 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-2024-8698 | 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-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-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-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-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-2024-1300 | 1 Redhat | 20 A Mq Clients, Amq Broker, Amq Streams and 17 more | 2026-04-15 | 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-2024-2700 | 1 Redhat | 11 Amq Streams, Apache Camel Hawtio, Apicurio Registry and 8 more | 2026-04-15 | 7 High |
| A vulnerability was found in the quarkus-core component. Quarkus captures local environment variables from the Quarkus namespace during the application's build, therefore, running the resulting application inherits the values captured at build time. Some local environment variables may have been set by the developer or CI environment for testing purposes, such as dropping the database during application startup or trusting all TLS certificates to accept self-signed certificates. If these properties are configured using environment variables or the .env facility, they are captured into the built application, which can lead to dangerous behavior if the application does not override these values. This behavior only happens for configuration properties from the `quarkus.*` namespace. Application-specific properties are not captured. | ||||
| CVE-2024-3656 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On | 2026-04-15 | 8.1 High |
| A flaw was found in Keycloak. Certain endpoints in Keycloak's admin REST API allow low-privilege users to access administrative functionalities. This flaw allows users to perform actions reserved for administrators, potentially leading to data breaches or system compromise. | ||||
| 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-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-2024-4540 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Rhosemc | 2026-04-15 | 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. | ||||
| CVE-2025-3501 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-04-15 | 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-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-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-2024-9666 | 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-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. | ||||
