CVE-2024-4629 | 1 Redhat | 12 Build Keycloak, Build Of Keycloak, Enterprise Linux and 9 more | 2025-09-12 | 6.5 Medium |
A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems. | ||||
CVE-2024-4540 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Rhosemc | 2025-09-12 | 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-2024-5967 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Rhosemc | 2025-09-12 | 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-2023-6484 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Rhosemc | 2025-09-12 | 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-2024-8883 | 1 Redhat | 10 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 7 more | 2025-09-12 | 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-2024-7341 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Enterprise Linux and 5 more | 2025-09-12 | 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-2024-10234 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Jboss Data Grid and 5 more | 2025-09-12 | 6.1 Medium |
A vulnerability was found in Wildfly, where a user may perform Cross-site scripting in the Wildfly deployment system. This flaw allows an attacker or insider to execute a deployment with a malicious payload, which could trigger undesired behavior against the server. | ||||
CVE-2023-6927 | 1 Redhat | 5 Build Keycloak, Keycloak, Red Hat Single Sign On and 2 more | 2025-09-12 | 4.6 Medium |
A flaw was found in Keycloak. This issue may allow an attacker to steal authorization codes or tokens from clients using a wildcard in the JARM response mode "form_post.jwt" which could be used to bypass the security patch implemented to address CVE-2023-6134. | ||||
CVE-2023-6134 | 1 Redhat | 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more | 2025-09-12 | 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-2024-8698 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On and 1 more | 2025-09-12 | 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-2024-3656 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On | 2025-09-12 | 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-2023-6291 | 1 Redhat | 18 Build Keycloak, Enterprise Linux, Jboss Data Grid and 15 more | 2025-09-12 | 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-2025-9784 | 1 Redhat | 15 Apache Camel Hawtio, Build Of Apache Camel For Spring Boot, Camel Spring Boot and 12 more | 2025-09-12 | 7.5 High |
A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS). | ||||
CVE-2024-10492 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more | 2025-09-02 | 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-2024-5971 | 1 Redhat | 12 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 9 more | 2025-09-01 | 7.5 High |
A vulnerability was found in Undertow, where the chunked response hangs after the body was flushed. The response headers and body were sent but the client would continue waiting as Undertow does not send the expected 0\r\n termination of the chunked response. This results in uncontrolled resource consumption, leaving the server side to a denial of service attack. This happens only with Java 17 TLSv1.3 scenarios. | ||||
CVE-2025-23367 | 1 Redhat | 7 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 4 more | 2025-08-30 | 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-2025-2559 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2025-08-30 | 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-2025-0604 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2025-08-30 | 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-2024-10451 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On | 2025-08-30 | 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-2024-10270 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more | 2025-08-30 | 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. |
