CVE-2024-1722 1 Redhat 3 Build Keycloak, Keycloak, Red Hat Single Sign On 2025-11-21 3.7 Low
A flaw was found in Keycloak. In certain conditions, this issue may allow a remote unauthenticated attacker to block other accounts from logging in.
CVE-2023-6484 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2025-11-21 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-2025-2559 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-11-20 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-2024-7260 1 Redhat 3 Build Keycloak, Build Of Keycloak, Keycloak 2025-11-20 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-2025-3910 1 Redhat 2 Build Keycloak, Build Of Keycloak 2025-11-20 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-2025-0604 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-11-20 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-2025-1391 1 Redhat 1 Build Keycloak 2025-11-20 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.
CVE-2024-11736 1 Redhat 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp 2025-11-20 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 2025-11-20 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-2024-10973 1 Redhat 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp 2025-11-20 5.7 Medium
A vulnerability was found in Keycloak. The environment option `KC_CACHE_EMBEDDED_MTLS_ENABLED` does not work and the JGroups replication configuration is always used in plain text which can allow an attacker that has access to adjacent networks related to JGroups to read sensitive information.
CVE-2023-6717 1 Redhat 15 Amq Broker, Build Keycloak, Jboss Data Grid and 12 more 2025-11-20 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-2025-23368 1 Redhat 10 Build Keycloak, Data Grid, Integration and 7 more 2025-11-20 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-2024-8698 1 Redhat 4 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On and 1 more 2025-11-20 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-2025-3501 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-11-20 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-2024-3656 1 Redhat 3 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On 2025-11-20 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-2024-1249 1 Redhat 15 Amq Broker, Amq Streams, Build Keycloak and 12 more 2025-11-20 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-2024-7341 1 Redhat 8 Build Keycloak, Build Of Keycloak, Enterprise Linux and 5 more 2025-11-13 7.1 High
A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation.
CVE-2024-9666 1 Redhat 2 Build Keycloak, Jboss Enterprise Application Platform 2025-11-11 4.7 Medium
A vulnerability was found in the Keycloak Server. The Keycloak Server is vulnerable to a denial of service (DoS) attack due to improper handling of proxy headers. When Keycloak is configured to accept incoming proxy headers, it may accept non-IP values, such as obfuscated identifiers, without proper validation. This issue can lead to costly DNS resolution operations, which an attacker could exploit to tie up IO threads and potentially cause a denial of service. The attacker must have access to send requests to a Keycloak instance that is configured to accept proxy headers, specifically when reverse proxies do not overwrite incoming headers, and Keycloak is configured to trust these headers.
CVE-2024-10492 1 Redhat 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more 2025-11-11 N/A
A vulnerability was found in Keycloak. A user with high privileges could read sensitive information from a Vault file that is not within the expected context. This attacker must have previous high access to the Keycloak server in order to perform resource creation, for example, an LDAP provider configuration and set up a Vault read file, which will only inform whether that file exists or not.
CVE-2023-6134 1 Redhat 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more 2025-11-11 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.
