| CVE-2023-6291 | 1 Redhat | 18 Build Keycloak, Enterprise Linux, Jboss Data Grid and 15 more | 2025-11-11 | 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-2023-6787 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Keycloak and 1 more | 2025-11-11 | 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-2023-6927 | 1 Redhat | 5 Build Keycloak, Keycloak, Red Hat Single Sign On and 2 more | 2025-11-11 | 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-2023-6563 | 1 Redhat | 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more | 2025-11-11 | 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-2023-6841 | 1 Redhat | 7 Jboss Enterprise Bpms Platform, Jboss Fuse, Keycloak and 4 more | 2025-11-08 | 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-2020-35509 | 1 Redhat | 2 Keycloak, Red Hat Single Sign On | 2025-06-30 | 5.4 Medium |
| A flaw was found in keycloak affecting versions 11.0.3 and 12.0.0. An expired certificate would be accepted by the direct-grant authenticator because of missing time stamp validations. The highest threat from this vulnerability is to data confidentiality and integrity. | ||||
| CVE-2017-12160 | 1 Redhat | 3 Jboss Single Sign On, Keycloak, Red Hat Single Sign On | 2025-04-20 | 7.2 High |
| It was found that Keycloak oauth would permit an authenticated resource to obtain an access/refresh token pair from the authentication server, permitting indefinite usage in the case of permission revocation. An attacker on an already compromised resource could use this flaw to grant himself continued permissions and possibly conduct further attacks. | ||||
| CVE-2023-0091 | 1 Redhat | 4 Keycloak, Red Hat Single Sign On, Rhosemc and 1 more | 2025-04-09 | 3.8 Low |
| A flaw was found in Keycloak, where it did not properly check client tokens for possible revocation in its client credential flow. This flaw allows an attacker to access or modify potentially sensitive information. | ||||
| CVE-2023-0105 | 1 Redhat | 4 Keycloak, Red Hat Single Sign On, Rhosemc and 1 more | 2025-04-09 | 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. | ||||
| CVE-2022-3782 | 1 Redhat | 8 Amq Broker, Jboss Enterprise Bpms Platform, Keycloak and 5 more | 2025-04-09 | 9.1 Critical |
| keycloak: path traversal via double URL encoding. A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. An attacker can use this flaw to construct a malicious request to bypass validation and access other URLs and potentially sensitive information within the domain or possibly conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field. | ||||
| CVE-2023-1664 | 1 Redhat | 8 Amq Broker, Build Of Quarkus, Jboss A-mq and 5 more | 2025-01-15 | 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-2023-4918 | 1 Redhat | 2 Keycloak, Red Hat Single Sign On | 2024-11-21 | 8.8 High |
| A flaw was found in the Keycloak package, more specifically org.keycloak.userprofile. When a user registers itself through registration flow, the "password" and "password-confirm" field from the form will occur as regular user attributes. All users and clients with proper rights and roles are able to read users attributes, allowing a malicious user with minimal access to retrieve the users passwords in clear text, jeopardizing their environment. | ||||
| CVE-2023-2422 | 1 Redhat | 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more | 2024-11-21 | 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-2023-0264 | 1 Redhat | 8 Enterprise Linux, Keycloak, Openshift Container Platform and 5 more | 2024-11-21 | 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-2022-4361 | 1 Redhat | 8 Enterprise Linux, Keycloak, Openshift Container Platform and 5 more | 2024-11-21 | 10 Critical |
| Keycloak, an open-source identity and access management solution, has a cross-site scripting (XSS) vulnerability in the SAML or OIDC providers. The vulnerability can allow an attacker to execute malicious scripts by setting the AssertionConsumerServiceURL value or the redirect_uri. | ||||
| CVE-2022-4137 | 1 Redhat | 4 Enterprise Linux, Keycloak, Red Hat Single Sign On and 1 more | 2024-11-21 | 8.1 High |
| A reflected cross-site scripting (XSS) vulnerability was found in the 'oob' OAuth endpoint due to incorrect null-byte handling. This issue allows a malicious link to insert an arbitrary URI into a Keycloak error page. This flaw requires a user or administrator to interact with a link in order to be vulnerable. This may compromise user details, allowing it to be changed or collected by an attacker. | ||||
| CVE-2022-3916 | 1 Redhat | 9 Enterprise Linux, Keycloak, Openshift Container Platform and 6 more | 2024-11-21 | 6.8 Medium |
| A flaw was found in the offline_access scope in Keycloak. This issue would affect users of shared computers more (especially if cookies are not cleared), due to a lack of root session validation, and the reuse of session ids across root and user authentication sessions. This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user. | ||||
| CVE-2022-2668 | 1 Redhat | 3 Keycloak, Red Hat Single Sign On, Single Sign-on | 2024-11-21 | 7.2 High |
| An issue was discovered in Keycloak that allows arbitrary Javascript to be uploaded for the SAML protocol mapper even if the UPLOAD_SCRIPTS feature is disabled | ||||
