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-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-2024-4540 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).

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-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-2024-1249 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-2024-4028 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-2024-4027 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-2024-8698 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-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-2023-4639 1 Redhat 14 Camel Quarkus, Camel Spring Boot, Integration and 11 more 2026-04-15 7.4 High
A flaw was found in Undertow, which incorrectly parses cookies with certain value-delimiting characters in incoming requests. This issue could allow an attacker to construct a cookie value to exfiltrate HttpOnly cookie values or spoof arbitrary additional cookie values, leading to unauthorized data access or modification. The main threat from this flaw impacts data confidentiality and integrity.
CVE-2024-10270 1 Redhat 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more 2026-04-15 6.5 Medium
A vulnerability was found in the Keycloak-services package. If untrusted data is passed to the SearchQueryUtils method, it could lead to a denial of service (DoS) scenario by exhausting system resources due to a Regex complexity.
CVE-2023-6484 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2026-04-15 5.3 Medium
A log injection flaw was found in Keycloak. A text string may be injected through the authentication form when using the WebAuthn authentication mode. This issue may have a minor impact to the logs integrity.
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-2025-12789 1 Redhat 1 Red Hat Single Sign On 2026-04-15 6.1 Medium
A flaw was found in Red Hat Single Sign-On. This issue is an Open Redirect vulnerability that occurs during the logout process. The redirect_uri parameter associated with the openid-connect logout protocol does not properly validate the provided URL.
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-2020-11022 9 Debian, Drupal, Fedoraproject and 6 more 88 Debian Linux, Drupal, Fedora and 85 more 2026-04-13 6.9 Medium
In jQuery starting with 1.12.0 and before 3.5.0, passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
CVE-2026-28367 1 Redhat 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more 2026-04-13 8.7 High
A flaw was found in Undertow. A remote attacker can exploit this vulnerability by sending `\r\r\r` as a header block terminator. This can be used for request smuggling with certain proxy servers, such as older versions of Apache Traffic Server and Google Cloud Classic Application Load Balancer, potentially leading to unauthorized access or manipulation of web requests.
CVE-2026-3260 1 Redhat 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more 2026-04-09 5.9 Medium
A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending an HTTP GET request containing multipart/form-data content. If the underlying application processes parameters using methods like `getParameterMap()`, the server prematurely parses and stores this content to disk. This could lead to resource exhaustion, potentially resulting in a Denial of Service (DoS).
