| 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-2023-6841 | 1 Redhat | 7 Jboss Enterprise Bpms Platform, Jboss Fuse, Keycloak and 4 more | 2025-08-07 | 7.5 High |
| A denial of service vulnerability was found in keycloak where the amount of attributes per object is not limited,an attacker by sending repeated HTTP requests could cause a resource exhaustion when the application send back rows with long attribute values. | ||||
| CVE-2023-6717 | 1 Redhat | 15 Amq Broker, Build Keycloak, Jboss Data Grid and 12 more | 2025-08-07 | 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-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-2023-6291 | 1 Redhat | 18 Build Keycloak, Enterprise Linux, Jboss Data Grid and 15 more | 2025-08-07 | 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-2024-4540 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Rhosemc | 2025-08-07 | 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 | 2025-08-07 | 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-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-2023-6927 | 1 Redhat | 5 Build Keycloak, Keycloak, Red Hat Single Sign On and 2 more | 2025-08-07 | 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-2023-6787 | 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-2023-6134 | 1 Redhat | 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more | 2025-08-07 | 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-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-2023-5379 | 1 Redhat | 11 Jboss Data Grid, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Eus and 8 more | 2025-08-04 | 7.5 High |
| A flaw was found in Undertow. When an AJP request is sent that exceeds the max-header-size attribute in ajp-listener, JBoss EAP is marked in an error state by mod_cluster in httpd, causing JBoss EAP to close the TCP connection without returning an AJP response. This happens because mod_proxy_cluster marks the JBoss EAP instance as an error worker when the TCP connection is closed from the backend after sending the AJP request without receiving an AJP response, and stops forwarding. This issue could allow a malicious user could to repeatedly send requests that exceed the max-header-size, causing a Denial of Service (DoS). | ||||
| CVE-2024-5971 | 1 Redhat | 12 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 9 more | 2025-08-02 | 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-2020-11023 | 8 Debian, Drupal, Fedoraproject and 5 more | 78 Debian Linux, Drupal, Fedora and 75 more | 2025-07-30 | 6.9 Medium |
| In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0. | ||||
