| CVE-2026-3872 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-16 | 7.3 High |
| A flaw was found in Keycloak. This issue allows an attacker, who controls another path on the same web server, to bypass the allowed path in redirect Uniform Resource Identifiers (URIs) that use a wildcard. A successful attack may lead to the theft of an access token, resulting in information disclosure. | ||||
| CVE-2026-4282 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-16 | 7.4 High |
| A flaw was found in Keycloak. The SingleUseObjectProvider, a global key-value store, lacks proper type and namespace isolation. This vulnerability allows an unauthenticated attacker to forge authorization codes. Successful exploitation can lead to the creation of admin-capable access tokens, resulting in privilege escalation. | ||||
| CVE-2026-4325 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-16 | 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-2026-4634 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-16 | 7.5 High |
| A flaw was found in Keycloak. An unauthenticated attacker can exploit this vulnerability by sending a specially crafted POST request with an excessively long scope parameter to the OpenID Connect (OIDC) token endpoint. This leads to high resource consumption and prolonged processing times, ultimately resulting in a Denial of Service (DoS) for the Keycloak server. | ||||
| CVE-2026-4636 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-04-16 | 8.1 High |
| A flaw was found in Keycloak. An authenticated user with the uma_protection role can bypass User-Managed Access (UMA) policy validation. This allows the attacker to include resource identifiers owned by other users in a policy creation request, even if the URL path specifies an attacker-owned resource. Consequently, the attacker gains unauthorized permissions to victim-owned resources, enabling them to obtain a Requesting Party Token (RPT) and access sensitive information or perform unauthorized actions. | ||||
| CVE-2026-2733 | 1 Redhat | 7 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 4 more | 2026-04-16 | 3.8 Low |
| A flaw was identified in the Docker v2 authentication endpoint of Keycloak, where tokens continue to be issued even after a Docker registry client has been administratively disabled. This means that turning the client “Enabled” setting to OFF does not fully prevent access. As a result, previously valid credentials can still be used to obtain authentication tokens. This weakens administrative controls and could allow unintended access to container registry resources. | ||||
| CVE-2026-0871 | 1 Redhat | 7 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 4 more | 2026-04-16 | 4.9 Medium |
| A flaw was found in Keycloak. An administrator with `manage-users` permission can bypass the "Only administrators can view" setting for unmanaged attributes, allowing them to modify these attributes. This improper access control can lead to unauthorized changes to user profiles, even when the system is configured to restrict such modifications. | ||||
| CVE-2026-3009 | 1 Redhat | 7 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 4 more | 2026-04-16 | 8.1 High |
| A security flaw in the IdentityBrokerService.performLogin endpoint of Keycloak allows authentication to proceed using an Identity Provider (IdP) even after it has been disabled by an administrator. An attacker who knows the IdP alias can reuse a previously generated login request to bypass the administrative restriction. This undermines access control enforcement and may allow unauthorized authentication through a disabled external provider. | ||||
| CVE-2026-1035 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more | 2026-04-16 | 3.1 Low |
| A flaw was found in the Keycloak server during refresh token processing, specifically in the TokenManager class responsible for enforcing refresh token reuse policies. When strict refresh token rotation is enabled, the validation and update of refresh token usage are not performed atomically. This allows concurrent refresh requests to bypass single-use enforcement and issue multiple access tokens from the same refresh token. As a result, Keycloak’s refresh token rotation hardening can be undermined. | ||||
| CVE-2026-3121 | 2 Keycloak, Redhat | 8 Keycloak, Build Keycloak, Build Of Keycloak and 5 more | 2026-04-15 | 6.5 Medium |
| A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level. | ||||
| CVE-2026-1180 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more | 2026-04-15 | 5.8 Medium |
| A flaw was identified in Keycloak’s OpenID Connect Dynamic Client Registration feature when clients authenticate using private_key_jwt. The issue allows a client to specify an arbitrary jwks_uri, which Keycloak then retrieves without validating the destination. This enables attackers to coerce the Keycloak server into making HTTP requests to internal or restricted network resources. As a result, attackers can probe internal services and cloud metadata endpoints, creating an information disclosure and reconnaissance risk. | ||||
| CVE-2026-3190 | 2 Keycloak, Redhat | 3 Keycloak, Build Keycloak, Build Of Keycloak | 2026-04-15 | 4.3 Medium |
| A flaw was found in Keycloak. The User-Managed Access (UMA) 2.0 Protection API endpoint for permission tickets fails to enforce the `uma_protection` role check. This allows any authenticated user with a token issued for a resource server client, even without the `uma_protection` role, to enumerate all permission tickets in the system. This vulnerability partial leads to information disclosure. | ||||
| 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-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-2025-13467 | 1 Redhat | 1 Build Keycloak | 2026-04-15 | 5.5 Medium |
| A flaw was found in the Keycloak LDAP User Federation provider. This vulnerability allows an authenticated realm administrator to trigger deserialization of untrusted Java objects via a malicious LDAP server configuration. | ||||
| 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-2024-12397 | 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-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-2025-11538 | 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-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. | ||||
