| 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. | |||||

| 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-2023-6841 | 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-2023-6563 | 1 Redhat | 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more | 2026-06-17 | N/A | 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-2023-6291 | 1 Redhat | 8 Enterprise Linux, Keycloak, Migration Toolkit For Applications and 5 more | 2026-06-17 | N/A | 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-2023-6134 | 1 Redhat | 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more | 2026-06-17 | N/A | 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-2023-48795 | 42 9bis, Apache, Apple and 39 more | 68 Kitty, Sshd, Sshj and 65 more | 2026-06-17 | N/A | 5.9 MEDIUM |
| The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

| 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 |
