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-2025-9784 1 Redhat 15 Apache Camel Hawtio, Build Of Apache Camel For Spring Boot, Camel Spring Boot and 12 more 2025-09-17 7.5 High
A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS).
CVE-2024-7341 1 Redhat 8 Build Keycloak, Build Of Keycloak, Enterprise Linux and 5 more 2025-09-17 7.1 High
A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation.
CVE-2024-3653 1 Redhat 17 Amq Streams, Apache Camel Hawtio, Build Keycloak and 14 more 2025-09-16 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-2024-4029 1 Redhat 7 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 4 more 2025-09-16 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-2023-5379 1 Redhat 11 Jboss Data Grid, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Eus and 8 more 2025-09-16 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 2025-09-15 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-2024-4629 1 Redhat 12 Build Keycloak, Build Of Keycloak, Enterprise Linux and 9 more 2025-09-12 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-2024-4540 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-2023-6484 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2025-09-12 5.3 Medium
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-2024-8883 1 Redhat 10 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 7 more 2025-09-12 6.1 Medium
A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking.
CVE-2024-10234 1 Redhat 8 Build Keycloak, Build Of Keycloak, Jboss Data Grid and 5 more 2025-09-12 6.1 Medium
A vulnerability was found in Wildfly, where a user may perform Cross-site scripting in the Wildfly deployment system. This flaw allows an attacker or insider to execute a deployment with a malicious payload, which could trigger undesired behavior against the server.
CVE-2023-6927 1 Redhat 5 Build Keycloak, Keycloak, Red Hat Single Sign On and 2 more 2025-09-12 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-2023-6134 1 Redhat 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more 2025-09-12 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-2024-8698 1 Redhat 4 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On and 1 more 2025-09-12 7.7 High
A flaw exists in the SAML signature validation method within the Keycloak XMLSignatureUtil class. The method incorrectly determines whether a SAML signature is for the full document or only for specific assertions based on the position of the signature in the XML document, rather than the Reference element used to specify the signed element. This flaw allows attackers to create crafted responses that can bypass the validation, potentially leading to privilege escalation or impersonation attacks.
CVE-2024-3656 1 Redhat 3 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On 2025-09-12 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-2023-6291 1 Redhat 18 Build Keycloak, Enterprise Linux, Jboss Data Grid and 15 more 2025-09-12 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-2024-10492 1 Redhat 4 Build Keycloak, Jboss Enterprise Application Platform, Jbosseapxp and 1 more 2025-09-02 N/A
A vulnerability was found in Keycloak. A user with high privileges could read sensitive information from a Vault file that is not within the expected context. This attacker must have previous high access to the Keycloak server in order to perform resource creation, for example, an LDAP provider configuration and set up a Vault read file, which will only inform whether that file exists or not.
CVE-2025-23367 1 Redhat 7 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 4 more 2025-08-30 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.
