CVE-2024-1635 2 Netapp, Redhat 26 Active Iq Unified Manager, Oncommand Workflow Automation, Amq Streams and 23 more 2025-08-14 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-2024-7885 1 Redhat 20 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 17 more 2025-08-14 7.5 High
A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.
CVE-2023-5685 1 Redhat 12 Apache-camel-spring-boot, Apache Camel Hawtio, Build Keycloak and 9 more 2025-08-14 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-2025-5416 1 Redhat 2 Build Keycloak, Keycloak 2025-08-13 2.7 Low
A vulnerability has been identified in Keycloak that could lead to unauthorized information disclosure. While it requires an already authenticated user, the /admin/serverinfo endpoint can inadvertently provide sensitive environment information.
CVE-2024-1300 1 Redhat 20 A Mq Clients, Amq Broker, Amq Streams and 17 more 2025-08-12 5.4 Medium
A vulnerability in the Eclipse Vert.x toolkit causes a memory leak in TCP servers configured with TLS and SNI support. When processing an unknown SNI server name assigned the default certificate instead of a mapped certificate, the SSL context is erroneously cached in the server name map, leading to memory exhaustion. This flaw allows attackers to send TLS client hello messages with fake server names, triggering a JVM out-of-memory error.
CVE-2024-1023 1 Redhat 20 A Mq Clients, Amq Broker, Amq Streams and 17 more 2025-08-12 6.5 Medium
A vulnerability in the Eclipse Vert.x toolkit results in a memory leak due to using Netty FastThreadLocal data structures. Specifically, when the Vert.x HTTP client establishes connections to different hosts, triggering the memory leak. The leak can be accelerated with intimate runtime knowledge, allowing an attacker to exploit this vulnerability. For instance, a server accepting arbitrary internet addresses could serve as an attack vector by connecting to these addresses, thereby accelerating the memory leak.
CVE-2025-23368 1 Redhat 8 Build Keycloak, Integration, Jboss Data Grid and 5 more 2025-08-12 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-2025-7784 1 Redhat 5 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 2 more 2025-08-11 6.5 Medium
A flaw was found in the Keycloak identity and access management system when Fine-Grained Admin Permissions(FGAPv2) are enabled. An administrative user with the manage-users role can escalate their privileges to realm-admin due to improper privilege enforcement. This vulnerability allows unauthorized elevation of access rights, compromising the intended separation of administrative duties and posing a security risk to the realm.
CVE-2025-3501 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-08-07 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-2024-1249 1 Redhat 15 Amq Broker, Amq Streams, Build Keycloak and 12 more 2025-08-07 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-2024-1132 1 Redhat 23 Amq Broker, Build Keycloak, Build Of Keycloak and 20 more 2025-08-07 8.1 High
A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. This issue could allow an attacker to construct a malicious request to bypass validation and access other URLs and sensitive information within the domain or conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field, and requires user interaction within the malicious URL.
CVE-2024-4028 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2025-08-07 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-2024-1722 1 Redhat 3 Build Keycloak, Keycloak, Red Hat Single Sign On 2025-08-07 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-2023-6787 1 Redhat 4 Build Keycloak, Build Of Keycloak, Keycloak and 1 more 2025-08-07 6.5 Medium
A flaw was found in Keycloak that occurs from an error in the re-authentication mechanism within org.keycloak.authentication. This flaw allows hijacking an active Keycloak session by triggering a new authentication process with the query parameter "prompt=login," prompting the user to re-enter their credentials. If the user cancels this re-authentication by selecting "Restart login," an account takeover may occur, as the new session, with a different SUB, will possess the same SID as the previous session.
CVE-2023-6544 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2025-08-07 5.4 Medium
A flaw was found in the Keycloak package. This issue occurs due to a permissive regular expression hardcoded for filtering which allows hosts to register a dynamic client. A malicious user with enough information about the environment could jeopardize an environment with this specific Dynamic Client Registration and TrustedDomain configuration previously unauthorized.
CVE-2023-6563 1 Redhat 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more 2025-08-07 7.7 High
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
CVE-2024-3653 1 Redhat 17 Amq Streams, Apache Camel Hawtio, Build Keycloak and 14 more 2025-08-06 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.
CVE-2024-12397 1 Redhat 13 Amq Streams, Apache Camel Hawtio, Build Keycloak and 10 more 2025-08-04 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-2024-1597 4 Fedoraproject, Pgjdbc, Postgresql and 1 more 14 Fedora, Pgjdbc, Postgresql Jdbc Driver and 11 more 2025-06-12 10 Critical
pgjdbc, the PostgreSQL JDBC Driver, allows attacker to inject SQL if using PreferQueryMode=SIMPLE. Note this is not the default. In the default mode there is no vulnerability. A placeholder for a numeric value must be immediately preceded by a minus. There must be a second placeholder for a string value after the first placeholder; both must be on the same line. By constructing a matching string payload, the attacker can inject SQL to alter the query,bypassing the protections that parameterized queries bring against SQL Injection attacks. Versions before 42.7.2, 42.6.1, 42.5.5, 42.4.4, 42.3.9, and 42.2.28 are affected.
CVE-2024-10039 1 Redhat 1 Build Keycloak 2024-11-21 7.1 High
A vulnerability was found in Keycloak. Deployments of Keycloak with a reverse proxy not using pass-through termination of TLS, with mTLS enabled, are affected. This issue may allow an attacker on the local network to authenticate as any user or client that leverages mTLS as the authentication mechanism.
