| CVE-2023-6484 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Rhosemc | 2026-03-02 | 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-2026-0871 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more | 2026-02-27 | 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-2025-12150 | 1 Redhat | 1 Build Keycloak | 2026-02-27 | 3.1 Low |
| A flaw was found in Keycloak’s WebAuthn registration component. This vulnerability allows an attacker to bypass the configured attestation policy and register untrusted or forged authenticators via submission of an attestation object with fmt: "none", even when the realm is configured to require direct attestation. This can lead to weakened authentication integrity and unauthorized authenticator registration. | ||||
| CVE-2026-1190 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more | 2026-02-26 | 3.1 Low |
| A flaw was found in Keycloak's SAML brokering functionality. When Keycloak is configured as a client in a Security Assertion Markup Language (SAML) setup, it fails to validate the `NotOnOrAfter` timestamp within the `SubjectConfirmationData`. This allows an attacker to delay the expiration of SAML responses, potentially extending the time a response is considered valid and leading to unexpected session durations or resource consumption. | ||||
| CVE-2024-6162 | 1 Redhat | 11 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 8 more | 2026-02-25 | 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 | 2026-02-25 | 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-2024-1300 | 1 Redhat | 20 A Mq Clients, Amq Broker, Amq Streams and 17 more | 2026-02-25 | 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-2024-1132 | 1 Redhat | 23 Amq Broker, Build Keycloak, Build Of Keycloak and 20 more | 2026-02-25 | 8.1 High |
| A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. This issue could allow an attacker to construct a malicious request to bypass validation and access other URLs and sensitive information within the domain or conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field, and requires user interaction within the malicious URL. | ||||
| CVE-2023-6134 | 1 Redhat | 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more | 2026-02-25 | 4.6 Medium |
| A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748. | ||||
| CVE-2026-2733 | 1 Redhat | 7 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 4 more | 2026-02-23 | 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-2024-1249 | 1 Redhat | 15 Amq Broker, Amq Streams, Build Keycloak and 12 more | 2026-02-20 | 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 | 2026-02-19 | 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-2026-1529 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-02-16 | 8.1 High |
| A flaw was found in Keycloak. An attacker can exploit this vulnerability by modifying the organization ID and target email within a legitimate invitation token's JSON Web Token (JWT) payload. This lack of cryptographic signature verification allows the attacker to successfully self-register into an unauthorized organization, leading to unauthorized access. | ||||
| CVE-2025-23368 | 1 Redhat | 10 Build Keycloak, Data Grid, Integration and 7 more | 2026-02-16 | 8.1 High |
| A flaw was found in Wildfly Elytron integration. The component does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks via CLI. | ||||
| CVE-2026-1486 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-02-10 | 8.8 High |
| A flaw was found in Keycloak. A vulnerability exists in the jwt-authorization-grant flow where the server fails to verify if an Identity Provider (IdP) is enabled before issuing tokens. The issuer lookup mechanism (lookupIdentityProviderFromIssuer) retrieves the IdP configuration but does not filter for isEnabled=false. If an administrator disables an IdP (e.g., due to a compromise or offboarding), an entity possessing that IdP's signing key can still generate valid JWT assertions that Keycloak accepts, resulting in the issuance of valid access tokens. | ||||
| CVE-2025-14778 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-02-10 | 5.4 Medium |
| A flaw was found in Keycloak. A significant Broken Access Control vulnerability exists in the UserManagedPermissionService (UMA Protection API). When updating or deleting a UMA policy associated with multiple resources, the authorization check only verifies the caller's ownership against the first resource in the policy's list. This allows a user (Owner A) who owns one resource (RA) to update a shared policy and modify authorization rules for other resources (e.g., RB) in that same policy, even if those other resources are owned by a different user (Owner B). This constitutes a horizontal privilege escalation. | ||||
| CVE-2025-11537 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-02-10 | 5 Medium |
| A flaw was found in Keycloak. When the logging format is configured to a verbose, user-supplied pattern (such as the pre-defined 'long' pattern), sensitive headers including Authorization and Cookie are disclosed to the logs in cleartext. An attacker with read access to the log files can extract these credentials (e.g., bearer tokens, session cookies) and use them to impersonate users, leading to a full account compromise. | ||||
| CVE-2025-23367 | 1 Redhat | 8 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 5 more | 2026-02-10 | 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. | ||||
| CVE-2025-14559 | 1 Redhat | 1 Build Keycloak | 2026-02-10 | 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-2025-13881 | 1 Redhat | 1 Build Keycloak | 2026-02-10 | 2.7 Low |
| A flaw was found in Keycloak Admin API. This vulnerability allows an administrator with limited privileges to retrieve sensitive custom attributes via the /unmanagedAttributes endpoint, bypassing User Profile visibility settings. | ||||
