Client Spoofing within the Keycloak Device Authorisation Grant
Under certain pre-conditions the vulnerability allows an attacker to spoof parts of the device flow and use a device_code to retrieve an access token for other OAuth clients.

Keycloak Server Private SPI: Improper Access Control Allows Administrators to Bypass Attribute Visibility Restrictions and Modify Unmanaged User Profile Attributes
A flaw was found in Keycloak. An administrator with `manage-users` permission can bypass the "Only administrators can view" setting for unmanaged attributes, allowing them to modify these attributes. This improper access control can lead to unauthorized changes to user profiles, even when the system is configured to restrict such modifications.

URL Redirection to Untrusted Site ('Open Redirect')
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.

Keycloak: Unauthorized authentication via disabled SAML Identity Provider
A flaw was found in Keycloak. A remote attacker could bypass security controls by sending a valid SAML response from an external Identity Provider (IdP) to the Keycloak SAML endpoint for IdP-initiated broker logins. This allows the attacker to complete broker logins even when the SAML Identity Provider is disabled, leading to unauthorized authentication.
