| CVE-2026-16102 | 1 Redhat | 4 Build Of Keycloak, Data Grid, Jboss Enterprise Application Platform Expansion Pack and 1 more | 2026-08-31 | N/A | 8.1 HIGH |
| A flaw was found in the Dynamic Client Registration (DCR) component of Keycloak, an identity and access management solution. The default DCR policy fails to properly validate the claim path for User Property mappers, allowing them to write values to sensitive internal claim locations. An attacker with a standard user account and a limited Initial Access Token can exploit this to forge administrative roles in their access token. This allows the attacker to take over other clients, steal confidential secrets, and potentially gain full administrative control over the realm. | |||||
| CVE-2026-15573 | 1 Redhat | 4 Build Of Keycloak, Data Grid, Jboss Enterprise Application Platform Expansion Pack and 1 more | 2026-08-31 | N/A | 8.1 HIGH |
| A flaw was found in Keycloak's Authorization Services. The component responsible for matching request paths to security policies (PathMatcher) does not properly normalize URIs before comparison. By adding extra characters like a trailing slash or matrix parameters to a URL, an attacker can trick the system into applying a less restrictive security policy than intended. This allows an authenticated user to access administrative or restricted areas they should not have permission to see. | |||||
| CVE-2024-7341 | 1 Redhat | 4 Build Of Keycloak, Enterprise Linux, Keycloak and 1 more | 2026-08-27 | N/A | 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-2023-44487 | 33 Akka, Amazon, Apache and 30 more | 324 Http Server, Opensearch Data Prepper, Apisix and 321 more | 2026-08-11 | N/A | 7.5 HIGH |
| The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. | |||||
| CVE-2023-5379 | 1 Redhat | 3 Jboss Enterprise Application Platform, Single Sign-on, Undertow | 2026-08-04 | N/A | 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-2024-1132 | 1 Redhat | 10 Build Of Keycloak, Jboss Middleware Text-only Advisories, Keycloak and 7 more | 2026-08-04 | N/A | 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-2024-8883 | 1 Redhat | 6 Build Of Keycloak, Openshift Container Platform, Openshift Container Platform For Ibm Z and 3 more | 2026-08-04 | N/A | 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-2026-4874 | 1 Redhat | 4 Build Of Keycloak, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack and 1 more | 2026-06-26 | N/A | 3.1 LOW |
| A flaw was found in Keycloak. An authenticated attacker can perform Server-Side Request Forgery (SSRF) by manipulating the `client_session_host` parameter during refresh token requests. This occurs when a Keycloak client is configured to use the `backchannel.logout.url` with the `application.session.host` placeholder. Successful exploitation allows the attacker to make HTTP requests from the Keycloak server’s network context, potentially probing internal networks or internal APIs, leading to information disclosure. | |||||
| CVE-2026-4366 | 1 Redhat | 4 Build Of Keycloak, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack and 1 more | 2026-06-17 | N/A | 5.8 MEDIUM |
| A flaw was identified in Keycloak, an identity and access management solution, where it improperly follows HTTP redirects when processing certain client configuration requests. This behavior allows an attacker to trick the server into making unintended requests to internal or restricted resources. As a result, sensitive internal services such as cloud metadata endpoints could be accessed. This issue may lead to information disclosure and enable attackers to map internal network infrastructure. | |||||
| CVE-2026-3121 | 1 Redhat | 4 Build Of Keycloak, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack and 1 more | 2026-06-17 | N/A | 6.5 MEDIUM |
| A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level. | |||||
| CVE-2024-4629 | 1 Redhat | 8 Build Of Keycloak, Enterprise Linux, Keycloak and 5 more | 2026-06-17 | N/A | 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-2023-6841 | 1 Redhat | 2 Keycloak, Single Sign-on | 2026-06-17 | N/A | 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-2023-3223 | 1 Redhat | 8 Enterprise Linux, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Text-only Advisories and 5 more | 2026-06-17 | N/A | 7.5 HIGH |
| A flaw was found in undertow. Servlets annotated with @MultipartConfig may cause an OutOfMemoryError due to large multipart content. This may allow unauthorized users to cause remote Denial of Service (DoS) attack. If the server uses fileSizeThreshold to limit the file size, it's possible to bypass the limit by setting the file name in the request to null. | |||||
| CVE-2023-2585 | 1 Redhat | 6 Enterprise Linux, Openshift Container Platform, Openshift Container Platform For Ibm Z and 3 more | 2026-06-17 | N/A | 3.5 LOW |
| Keycloak's device authorization grant does not correctly validate the device code and client ID. An attacker client could abuse the missing validation to spoof a client consent request and trick an authorization admin into granting consent to a malicious OAuth client or possible unauthorized access to an existing OAuth client. | |||||
| CVE-2023-2422 | 1 Redhat | 4 Enterprise Linux, Keycloak, Openshift Container Platform and 1 more | 2026-06-17 | N/A | 5.5 MEDIUM |
| A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients. | |||||
| CVE-2023-1932 | 2 Hibernate, Redhat | 5 Hibernate-validator, Codeready Studio, Jboss Enterprise Application Platform and 2 more | 2026-06-17 | N/A | 6.1 MEDIUM |
| A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class, which can be bypassed by omitting the tag ending in a less-than character. Browsers may render an invalid html, allowing HTML injection or Cross-Site-Scripting (XSS) attacks. | |||||
| CVE-2023-1664 | 1 Redhat | 5 Build Of Quarkus, Jboss A-mq, Keycloak and 2 more | 2026-06-17 | N/A | 6.5 MEDIUM |
| A flaw was found in Keycloak. This flaw depends on a non-default configuration "Revalidate Client Certificate" to be enabled and the reverse proxy is not validating the certificate before Keycloak. Using this method an attacker may choose the certificate which will be validated by the server. If this happens and the KC_SPI_TRUSTSTORE_FILE_FILE variable is missing/misconfigured, any trustfile may be accepted with the logging information of "Cannot validate client certificate trust: Truststore not available". This may not impact availability as the attacker would have no access to the server, but consumer applications Integrity or Confidentiality may be impacted considering a possible access to them. Considering the environment is correctly set to use "Revalidate Client Certificate" this flaw is avoidable. | |||||
| CVE-2023-1108 | 2 Netapp, Redhat | 17 Oncommand Workflow Automation, Build Of Quarkus, Decision Manager and 14 more | 2026-06-17 | N/A | 7.5 HIGH |
| A flaw was found in undertow. This issue makes achieving a denial of service possible due to an unexpected handshake status updated in SslConduit, where the loop never terminates. | |||||
| CVE-2023-0264 | 1 Redhat | 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more | 2026-06-17 | N/A | 5.0 MEDIUM |
| A flaw was found in Keycloaks OpenID Connect user authentication, which may incorrectly authenticate requests. An authenticated attacker who could obtain information from a user request within the same realm could use that data to impersonate the victim and generate new session tokens. This issue could impact confidentiality, integrity, and availability. | |||||
| CVE-2023-0105 | 1 Redhat | 2 Keycloak, Single Sign-on | 2026-06-17 | N/A | 6.5 MEDIUM |
| A flaw was found in Keycloak. This flaw allows impersonation and lockout due to the email trust not being handled correctly in Keycloak. An attacker can shadow other users with the same email and lockout or impersonate them. | |||||
