| CVE-2024-1023 | 1 Redhat | 20 A Mq Clients, Amq Broker, Amq Streams and 17 more | 2025-11-07 | 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-2024-1300 | 1 Redhat | 20 A Mq Clients, Amq Broker, Amq Streams and 17 more | 2025-11-07 | 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-2024-47072 | 2 Redhat, X-stream | 4 Build Keycloak, Jboss Data Grid, Ocp Tools and 1 more | 2025-11-03 | 7.5 High |
| XStream is a simple library to serialize objects to XML and back again. This vulnerability may allow a remote attacker to terminate the application with a stack overflow error resulting in a denial of service only by manipulating the processed input stream when XStream is configured to use the BinaryStreamDriver. XStream 1.4.21 has been patched to detect the manipulation in the binary input stream causing the the stack overflow and raises an InputManipulationException instead. Users are advised to upgrade. Users unable to upgrade may catch the StackOverflowError in the client code calling XStream if XStream is configured to use the BinaryStreamDriver. | ||||
| CVE-2024-1597 | 4 Fedoraproject, Pgjdbc, Postgresql and 1 more | 14 Fedora, Pgjdbc, Postgresql Jdbc Driver and 11 more | 2025-11-03 | 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-2025-23368 | 1 Redhat | 10 Build Keycloak, Data Grid, Integration and 7 more | 2025-10-14 | 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-2025-3501 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2025-09-25 | 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-2024-4629 | 1 Redhat | 12 Build Keycloak, Build Of Keycloak, Enterprise Linux and 9 more | 2025-09-23 | 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-2024-3656 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On | 2025-09-23 | 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-2024-4540 | 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-2025-8419 | 1 Redhat | 2 Build Keycloak, Keycloak | 2025-09-04 | 6.5 Medium |
| A vulnerability was found in Keycloak-services. Special characters used during e-mail registration may perform SMTP Injection and unexpectedly send short unwanted e-mails. The email is limited to 64 characters (limited local part of the email), so the attack is limited to very shorts emails (subject and little data, the example is 60 chars). This flaw's only direct consequence is an unsolicited email being sent from the Keycloak server. However, this action could be a precursor for more sophisticated attacks. | ||||
| CVE-2024-7318 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2025-09-02 | 4.8 Medium |
| A vulnerability was found in Keycloak. Expired OTP codes are still usable when using FreeOTP when the OTP token period is set to 30 seconds (default). Instead of expiring and deemed unusable around 30 seconds in, the tokens are valid for an additional 30 seconds totaling 1 minute. A one time passcode that is valid longer than its expiration time increases the attack window for malicious actors to abuse the system and compromise accounts. Additionally, it increases the attack surface because at any given time, two OTPs are valid. | ||||
| CVE-2024-7260 | 1 Redhat | 3 Build Keycloak, Build Of Keycloak, Keycloak | 2025-08-30 | 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-2025-2559 | 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-2025-1391 | 1 Redhat | 1 Build Keycloak | 2025-08-30 | 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-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-2024-11736 | 1 Redhat | 3 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp | 2025-08-30 | 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 | 2025-08-30 | 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 | 2025-08-30 | 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-2025-3910 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2025-08-18 | 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. | ||||
