| CVE-2026-18206 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-08-02 | 3.7 Low |
| A flaw was found in the keycloak-services component of Keycloak, which provides identity and access management services. The issue occurs when a realm administrator uses a wildcard domain (like *.example.com) to restrict which hosts can register or update clients. Due to improper validation, the system accepts any hostname that ends with the specified domain suffix, even if it is not a legitimate subdomain. An attacker who can control the reverse DNS of their connection can bypass these host-based restrictions, potentially allowing unauthorized client modifications. | ||||
| CVE-2026-18211 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-08-02 | 4.2 Medium |
| A flaw was found in the secure-client-uris client policy executor within Keycloak core services. This component is responsible for enforcing security requirements on client configurations, such as requiring encrypted connections for redirect URIs. Due to an improper check that only looks at the start of a web address rather than properly verifying the host, an attacker can bypass these security restrictions by using a specially crafted domain name. This could allow an attacker to intercept sensitive authentication codes over unencrypted connections. | ||||
| CVE-2026-18207 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-07-30 | 6.5 Medium |
| A flaw was found in the client policy enforcement mechanism of Keycloak. The issue occurs when the system checks group membership by name instead of a unique identifier. An attacker with client management privileges could bypass security policies by joining a group with a matching name in a different part of the group hierarchy, potentially allowing them to register or update clients without following required security hardening profiles. | ||||
| CVE-2026-14781 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-07-29 | 4.8 Medium |
| A flaw exists in the org.keycloak.broker.oidc package where the OIDC broker incorrectly synchronizes the email_verified claim. When an OIDC identity provider is configured with trustEmail=true and the userinfo endpoint is enabled, Keycloak retrieves the email address from the userinfo response but retrieves the email_verified status exclusively from the id_token. The root cause is a lack of validation ensuring that the email_verified claim in the id_token actually refers to the email address returned by the userinfo endpoint. If these two sources return different email addresses, the id_token's email_verified=true claim is blindly applied to the userinfo email. Exploitation Conditions: The OIDC identity provider must have trustEmail set to true (non-default). The userinfo endpoint must be enabled (default). The attacker must control or have compromised the upstream OIDC provider. Concrete Impact: Mark arbitrary email addresses as verified in the Keycloak database. Bypass email-based security controls or verification workflows. Potential account takeover if the application relies solely on the email_verified flag from the IdP to link accounts. | ||||
| CVE-2025-23368 | 1 Redhat | 11 Build Keycloak, Data Grid, Integration and 8 more | 2026-06-30 | 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-2026-11800 | 1 Redhat | 7 Build Keycloak, Build Of Keycloak, Data Grid and 4 more | 2026-06-26 | 8.1 High |
| A flaw was found in Keycloak. This JWT algorithm confusion vulnerability in the JWT Authorization Grant flow allows an attacker with valid client credentials to bypass signature verification. By forging an assertion, the attacker can create unauthorized access tokens. This enables the attacker to impersonate any federated user linked to the affected Identity Provider, leading to unauthorized access and potential privilege escalation. | ||||
| CVE-2024-4029 | 1 Redhat | 7 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 4 more | 2026-06-26 | 4.1 Medium |
| A vulnerability was found in Wildfly’s management interface. Due to the lack of limitation of sockets for the management interface, it may be possible to cause a denial of service hitting the nofile limit as there is no possibility to configure or set a maximum number of connections. | ||||
| CVE-2024-6875 | 1 Redhat | 1 Jboss Data Grid | 2026-06-26 | 6.5 Medium |

| CVE-2026-28369 | 1 Redhat | 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more | 2026-06-10 | 8.7 High |
| A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted information, or manipulate web caches, potentially leading to unauthorized actions or data exposure. | ||||
| CVE-2026-28368 | 1 Redhat | 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more | 2026-06-10 | 8.7 High |
| A flaw was found in Undertow. This vulnerability allows a remote attacker to construct specially crafted requests where header names are parsed differently by Undertow compared to upstream proxies. This discrepancy in header interpretation can be exploited to launch request smuggling attacks, potentially bypassing security controls and accessing unauthorized resources. | ||||
| CVE-2026-28367 | 1 Redhat | 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more | 2026-06-10 | 8.7 High |
| A flaw was found in Undertow. A remote attacker can exploit this vulnerability by sending `\r\r\r` as a header block terminator. This can be used for request smuggling with certain proxy servers, such as older versions of Apache Traffic Server and Google Cloud Classic Application Load Balancer, potentially leading to unauthorized access or manipulation of web requests. | ||||
| CVE-2021-44832 | 6 Apache, Cisco, Debian and 3 more | 31 Log4j, Cloudcenter, Debian Linux and 28 more | 2026-05-29 | 6.6 Medium |
| Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. | ||||

| JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. | ||||
| CVE-2019-17571 | 7 Apache, Canonical, Debian and 4 more | 26 Bookkeeper, Log4j, Ubuntu Linux and 23 more | 2026-05-28 | 9.8 Critical |
| Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17. | ||||
| CVE-2022-23302 | 6 Apache, Broadcom, Netapp and 3 more | 44 Log4j, Brocade Sannav, Snapmanager and 41 more | 2026-05-22 | 8.8 High |
| JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to. The attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-4104. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. | ||||
| CVE-2022-23305 | 6 Apache, Broadcom, Netapp and 3 more | 46 Log4j, Brocade Sannav, Snapmanager and 43 more | 2026-05-22 | 9.8 Critical |
| By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default. Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized SQL queries and further customization over the columns written to in logs. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. | ||||

| CVE-2024-3653 | 1 Redhat | 17 Amq Streams, Apache Camel Hawtio, Build Keycloak and 14 more | 2026-04-15 | 5.3 Medium |
| A vulnerability was found in Undertow. This issue requires enabling the learning-push handler in the server's config, which is disabled by default, leaving the maxAge config in the handler unconfigured. The default is -1, which makes the handler vulnerable. If someone overwrites that config, the server is not subject to the attack. The attacker needs to be able to reach the server with a normal HTTP request. | ||||
