| 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-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-2024-3656 | 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-2024-4027 | 1 Redhat | 17 Amq Streams, Apache Camel Hawtio, Build Keycloak and 14 more | 2026-04-15 | 7.5 High |
| A flaw was found in Undertow. Servlets using a method that calls HttpServletRequestImpl.getParameterNames() can cause an OutOfMemoryError when the client sends a request with large parameter names. This issue can be exploited by an unauthorized user to cause a remote denial-of-service (DoS) attack. | ||||
| 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-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-2024-5971 | 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-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-2025-10044 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 4.3 Medium |
| A flaw was found in Keycloak. Keycloak’s account console and other pages accept arbitrary text in the error_description query parameter. This text is directly rendered in error pages without validation or sanitization. While HTML encoding prevents XSS, an attacker can craft URLs with misleading messages (e.g., fake support phone numbers or URLs), which are displayed within the trusted Keycloak UI. This creates a phishing vector, potentially tricking users into contacting malicious actors. | ||||
| CVE-2025-10939 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 3.7 Low |
| A flaw was found in Keycloak. The Keycloak guides recommend to not expose /admin path to the outside in case the installation is using a proxy. The issue occurs at least via ha-proxy, as it can be tricked to using relative/non-normalized paths to access the /admin application path relative to /realms which is expected to be exposed. | ||||
| 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-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-2024-3884 | 1 Redhat | 19 Amq Streams, Apache Camel Hawtio, Build Keycloak and 16 more | 2026-04-15 | 7.5 High |
| A flaw was found in Undertow that can cause remote denial of service attacks. When the server uses the FormEncodedDataDefinition.doParse(StreamSourceChannel) method to parse large form data encoding with application/x-www-form-urlencoded, the method will cause an OutOfMemory issue. This flaw allows unauthorized users to cause a remote denial of service (DoS) attack. | ||||
| 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-2024-10451 | 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-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-2024-5967 | 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-2025-3501 | 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-2025-14559 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 6.5 Medium |
| A flaw was found in the keycloak-services component of Keycloak. This vulnerability allows the issuance of access and refresh tokens for disabled users, leading to unauthorized use of previously revoked privileges, via a business logic vulnerability in the Token Exchange implementation when a privileged client invokes the token exchange flow. | ||||
| CVE-2024-10492 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more | 2026-04-15 | N/A |
| A vulnerability was found in Keycloak. A user with high privileges could read sensitive information from a Vault file that is not within the expected context. This attacker must have previous high access to the Keycloak server in order to perform resource creation, for example, an LDAP provider configuration and set up a Vault read file, which will only inform whether that file exists or not. | ||||
