CVE-2026-19608 1 Redhat 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more 2026-08-21 5.3 Medium
A flaw was found in the group policy provider of Keycloak authorization services, which is used to manage fine-grained access control to resources. The issue occurs when the system evaluates group-based policies using tokens that only contain group names rather than full paths. If two groups in different parts of the organization share the same name, a user in the unauthorized group can be mistaken for a member of the authorized group. This can allow a user to gain unauthorized access to protected resources they should not be able to reach.
CVE-2026-18963 1 Redhat 6 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform Expansion Pack and 3 more 2026-08-21 9.1 Critical
A flaw was found in the reset-credentials flow of the keycloak-services component, which is the core engine for identity and access management in Red Hat Build of Keycloak. The issue allows an unauthenticated attacker to force the password reset process for any user without needing to click the required email verification link. This can result in the attacker gaining full control over target user accounts by directly setting new credentials.
CVE-2026-15571 1 Redhat 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more 2026-08-21 7.3 High
A flaw was found in the legacy client-initiated account-linking endpoint of Keycloak, a widely used open-source identity and access management solution. The mechanism used to protect the account-linking process from unauthorized requests relies on a hash that can be predicted by a malicious OIDC client. By tricking a user into authenticating, an attacker-controlled client can forge a valid linking URL to connect the victim's account to an attacker's external identity. This results in a full account takeover, allowing the attacker to log in as the victim.
CVE-2026-76166 1 Redhat 7 Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack, Jboss Enterprise Web Server and 4 more 2026-08-21 4.3 Medium
A flaw was found in mod_cluster's AdvertiseListenerImpl (org.jboss.modcluster core module). A single crafted UDP multicast datagram with a valid HTTP status line and a "Server:" header but without the "Date:", "Digest:", and "Sequence:" headers triggers a NullPointerException in verifyDigest() that is not caught by the worker thread's exception handler. This causes the advertise listener thread to terminate permanently. The failure is silent (isListening() continues to return true) and persists until the node is restarted. The crash occurs before the AdvertiseSecurityKey comparison, so deployments with a configured security key are still affected.
CVE-2026-19611 1 Redhat 14 Build Keycloak, Build Of Apache Camel For Quarkus, Build Of Debezium 3 and 11 more 2026-08-21 7.4 High
A flaw was found in WildFly Elytron. Password hashing and verification normalize input with Unicode NFKC, which can collapse fullwidth characters to ASCII equivalents. A remote attacker can more easily guess affected passwords by using an ASCII-only dictionary against accounts whose passwords were intended to include those non-ASCII characters, leading to unauthorized access.
CVE-2025-23367 1 Redhat 8 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 5 more 2026-08-21 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-2026-0603 1 Redhat 13 Amq Broker, Jboss Data Grid, Jboss Enterprise Application Platform and 10 more 2026-08-19 8.3 High
A flaw was found in Hibernate. A remote attacker with low privileges could exploit a second-order SQL injection vulnerability by providing specially crafted, unsanitized non-alphanumeric characters in the ID column when the InlineIdsOrClauseBuilder is used. This could lead to sensitive information disclosure, such as reading system files, and allow for data manipulation or deletion within the application's database, resulting in an application level denial of service.
CVE-2026-16102 1 Redhat 10 Build Keycloak, Build Of Keycloak, Data Grid and 7 more 2026-08-11 8.1 High
A flaw was found in the Dynamic Client Registration (DCR) component of Keycloak, an identity and access management solution. The default DCR policy fails to properly validate the claim path for User Property mappers, allowing them to write values to sensitive internal claim locations. An attacker with a standard user account and a limited Initial Access Token can exploit this to forge administrative roles in their access token. This allows the attacker to take over other clients, steal confidential secrets, and potentially gain full administrative control over the realm.
CVE-2024-11831 1 Redhat 34 Acm, Advanced Cluster Security, Ansible Automation Platform and 31 more 2026-06-29 5.4 Medium
A flaw was found in npm-serialize-javascript. The vulnerability occurs because the serialize-javascript module does not properly sanitize certain inputs, such as regex or other JavaScript object types, allowing an attacker to inject malicious code. This code could be executed when deserialized by a web browser, causing Cross-site scripting (XSS) attacks. This issue is critical in environments where serialized data is sent to web clients, potentially compromising the security of the website or web application using this package.
CVE-2025-2559 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2026-05-06 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-2024-4028 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2026-04-15 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-2022-2232 1 Redhat 1 Red Hat Single Sign On 2026-04-15 7.5 High
A flaw was found in the Keycloak package. This flaw allows an attacker to utilize an LDAP injection to bypass the username lookup or potentially perform other malicious actions.
CVE-2025-23368 1 Redhat 10 Build Keycloak, Data Grid, Integration and 7 more 2026-02-13 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-2024-1249 1 Redhat 15 Amq Broker, Amq Streams, Build Keycloak and 12 more 2026-02-09 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 2026-02-09 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-2025-12543 1 Redhat 9 Apache Camel Hawtio, Camel Spring Boot, Enterprise Linux and 6 more 2026-02-09 9.6 Critical
A flaw was found in the Undertow HTTP server core, which is used in WildFly, JBoss EAP, and other Java applications. The Undertow library fails to properly validate the Host header in incoming HTTP requests.As a result, requests containing malformed or malicious Host headers are processed without rejection, enabling attackers to poison caches, perform internal network scans, or hijack user sessions.
CVE-2024-4027 1 Redhat 17 Amq Streams, Apache Camel Hawtio, Build Keycloak and 14 more 2026-02-04 7.5 High
A flaw was found in Undertow. Servlets using a method that calls HttpServletRequestImpl.getParameterNames() can cause an OutOfMemoryError when the client sends a request with large parameter names. This issue can be exploited by an unauthorized user to cause a remote denial-of-service (DoS) attack.
CVE-2025-0604 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2026-01-29 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-2026-1190 1 Redhat 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more 2026-01-27 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-2024-3884 1 Redhat 17 Amq Streams, Apache Camel Hawtio, Build Keycloak and 14 more 2026-01-26 7.5 High
A flaw was found in Undertow that can cause remote denial of service attacks. When the server uses the FormEncodedDataDefinition.doParse(StreamSourceChannel) method to parse large form data encoding with application/x-www-form-urlencoded, the method will cause an OutOfMemory issue. This flaw allows unauthorized users to cause a remote denial of service (DoS) attack.
