| 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-2024-10451 | 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-2025-9162 | 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-2024-12369 | 1 Redhat | 2 Build Keycloak, Jboss Enterprise Application Platform | 2026-04-15 | 4.2 Medium |
| A vulnerability was found in OIDC-Client. When using the RH SSO OIDC adapter with EAP 7.x or when using the elytron-oidc-client subsystem with EAP 8.x, authorization code injection attacks can occur, allowing an attacker to inject a stolen authorization code into the attacker's own session with the client with a victim's identity. This is usually done with a Man-in-the-Middle (MitM) or phishing attack. | ||||
| CVE-2024-12397 | 1 Redhat | 13 Amq Streams, Apache Camel Hawtio, Build Keycloak and 10 more | 2026-04-15 | 7.4 High |
| A flaw was found in Quarkus-HTTP, 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-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-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-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-2023-6544 | 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-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-2024-5967 | 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-2024-1023 | 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-2024-10270 | 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-2024-11734 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp | 2026-04-15 | 6.5 Medium |
| A denial of service vulnerability was found in Keycloak that could allow an administrative user with the right to change realm settings to disrupt the service. This action is done by modifying any of the security headers and inserting newlines, which causes the Keycloak server to write to a request that has already been terminated, leading to the failure of said request. | ||||
| CVE-2024-11736 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp | 2026-04-15 | 4.9 Medium |
| A vulnerability was found in Keycloak. Admin users may have to access sensitive server environment variables and system properties through user-configurable URLs. When configuring backchannel logout URLs or admin URLs, admin users can include placeholders like ${env.VARNAME} or ${PROPNAME}. The server replaces these placeholders with the actual values of environment variables or system properties during URL processing. | ||||
| 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-2026-37977 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-07 | 3.7 Low |
| A flaw was found in Keycloak. A remote attacker can exploit a Cross-Origin Resource Sharing (CORS) header injection vulnerability in Keycloak's User-Managed Access (UMA) token endpoint. This flaw occurs because the `azp` claim from a client-supplied JSON Web Token (JWT) is used to set the `Access-Control-Allow-Origin` header before the JWT signature is validated. When a specially crafted JWT with an attacker-controlled `azp` value is processed, this value is reflected as the CORS origin, even if the grant is later rejected. This can lead to the exposure of low-sensitivity information from authorization server error responses, weakening origin isolation, but only when a target client is misconfigured with `webOrigins: ["*"]`. | ||||
| CVE-2026-4325 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-07 | 5.3 Medium |
| A flaw was found in Keycloak. The SingleUseObjectProvider, a global key-value store, lacks proper type and namespace isolation. This vulnerability allows an attacker to delete arbitrary single-use entries, which can enable the replay of consumed action tokens, such as password reset links. This could lead to unauthorized access or account compromise. | ||||
| CVE-2026-3911 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-02 | 2.7 Low |
| A flaw was found in Keycloak. An authenticated user with the view-users role could exploit a vulnerability in the UserResource component. By accessing a specific administrative endpoint, this user could improperly retrieve user attributes that were configured to be hidden. This unauthorized information disclosure could expose sensitive user data. | ||||
| CVE-2026-4366 | 1 Redhat | 7 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 4 more | 2026-04-02 | 5.8 Medium |
| A flaw was identified in Keycloak, an identity and access management solution, where it improperly follows HTTP redirects when processing certain client configuration requests. This behavior allows an attacker to trick the server into making unintended requests to internal or restricted resources. As a result, sensitive internal services such as cloud metadata endpoints could be accessed. This issue may lead to information disclosure and enable attackers to map internal network infrastructure. | ||||
