CVE-2024-7318 1 Redhat 2 Build Keycloak, Build Of Keycloak 2025-05-02 4.8 Medium
A vulnerability was found in Keycloak. Expired OTP codes are still usable when using FreeOTP when the OTP token period is set to 30 seconds (default). Instead of expiring and deemed unusable around 30 seconds in, the tokens are valid for an additional 30 seconds totaling 1 minute. A one time passcode that is valid longer than its expiration time increases the attack window for malicious actors to abuse the system and compromise accounts. Additionally, it increases the attack surface because at any given time, two OTPs are valid.
CVE-2024-8883 1 Redhat 10 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 7 more 2025-05-02 6.1 Medium
A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking.
CVE-2024-7260 1 Redhat 3 Build Keycloak, Build Of Keycloak, Keycloak 2025-05-02 6.1 Medium
An open redirect vulnerability was found in Keycloak. A specially crafted URL can be constructed where the referrer and referrer_uri parameters are made to trick a user to visit a malicious webpage. A trusted URL can trick users and automation into believing that the URL is safe, when, in fact, it redirects to a malicious server. This issue can result in a victim inadvertently trusting the destination of the redirect, potentially leading to a successful phishing attack or other types of attacks. Once a crafted URL is made, it can be sent to a Keycloak admin via email for example. This will trigger this vulnerability when the user visits the page and clicks the link. A malicious actor can use this to target users they know are Keycloak admins for further attacks. It may also be possible to bypass other domain-related security checks, such as supplying this as a OAuth redirect uri. The malicious actor can further obfuscate the redirect_uri using URL encoding, to hide the text of the actual malicious website domain.
CVE-2024-12397 1 Redhat 13 Amq Streams, Build Keycloak, Camel Quarkus and 10 more 2025-05-02 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-2025-3501 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-05-02 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-2025-3910 1 Redhat 1 Build Keycloak 2025-05-02 5.4 Medium
A flaw was found in Keycloak. The org.keycloak.authorization package may be vulnerable to circumventing required actions, allowing users to circumvent requirements such as setting up two-factor authentication.
CVE-2024-1249 1 Redhat 15 Amq Broker, Amq Streams, Build Keycloak and 12 more 2025-05-02 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-2025-0604 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-05-01 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-2025-2559 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-04-30 4.9 Medium
A flaw was found in Keycloak. When the configuration uses JWT tokens for authentication, the tokens are cached until expiration. If a client uses JWT tokens with an excessively long expiration time, for example, 24 or 48 hours, the cache can grow indefinitely, leading to an OutOfMemoryError. This issue could result in a denial of service condition, preventing legitimate users from accessing the system.
CVE-2025-23368 1 Redhat 8 Build Keycloak, Integration, Jboss Data Grid and 5 more 2025-04-28 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-2024-1635 1 Redhat 18 Amq Streams, Apache Camel Spring Boot, Build Keycloak and 15 more 2025-04-28 7.5 High
A vulnerability was found in Undertow. This vulnerability impacts a server that supports the wildfly-http-client protocol. Whenever a malicious user opens and closes a connection with the HTTP port of the server and then closes the connection immediately, the server will end with both memory and open file limits exhausted at some point, depending on the amount of memory available. At HTTP upgrade to remoting, the WriteTimeoutStreamSinkConduit leaks connections if RemotingConnection is closed by Remoting ServerConnectionOpenListener. Because the remoting connection originates in Undertow as part of the HTTP upgrade, there is an external layer to the remoting connection. This connection is unaware of the outermost layer when closing the connection during the connection opening procedure. Hence, the Undertow WriteTimeoutStreamSinkConduit is not notified of the closed connection in this scenario. Because WriteTimeoutStreamSinkConduit creates a timeout task, the whole dependency tree leaks via that task, which is added to XNIO WorkerThread. So, the workerThread points to the Undertow conduit, which contains the connections and causes the leak.
CVE-2025-23367 1 Redhat 7 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 4 more 2025-04-26 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-2024-12369 1 Redhat 2 Build Keycloak, Jboss Enterprise Application Platform 2025-04-17 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-2023-5685 1 Redhat 12 Apache-camel-spring-boot, Build Keycloak, Camel Spring Boot and 9 more 2025-04-16 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-2024-4028 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-04-07 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-2023-6291 1 Redhat 18 Build Keycloak, Enterprise Linux, Jboss Data Grid and 15 more 2025-04-04 7.1 High
A flaw was found in the redirect_uri validation logic in Keycloak. This issue may allow a bypass of otherwise explicitly allowed hosts. A successful attack may lead to an access token being stolen, making it possible for the attacker to impersonate other users.
CVE-2024-6162 1 Redhat 11 Apache Camel Spring Boot, Build Keycloak, Camel Spring Boot and 8 more 2025-03-25 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-2024-11736 1 Redhat 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp 2025-03-19 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-2024-11734 1 Redhat 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp 2025-03-19 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-2025-1391 1 Redhat 1 Build Keycloak 2025-03-15 5.4 Medium
A flaw was found in the Keycloak organization feature, which allows the incorrect assignment of an organization to a user if their username or email matches the organization’s domain pattern. This issue occurs at the mapper level, leading to misrepresentation in tokens. If an application relies on these claims for authorization, it may incorrectly assume a user belongs to an organization they are not a member of, potentially granting unauthorized access or privileges.
