Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A flaw was found in the Keycloak REST API before version 8.0.0 where it would permit user access from a realm the user was not configured. An authenticated attacker with knowledge of a user id could use this flaw to access unauthorized information or to carry out further attacks.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is an authorization bypass vulnerability in Keycloak's REST API versions before 8.0.0. The API failed to properly validate whether an authenticated user was authorized to access resources in a specific realm, allowing any authenticated user with knowledge of a target user ID to access that user's information across realms they were not assigned to.

MitigationUpgrade Keycloak to version 8.0.0 or later, which contains the fix for this authorization flaw.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Keycloak version
    Check the Keycloak server version through the admin console, startup logs, or by querying the /auth/realms/master endpoint (for older versions) or /realms/master (for newer versions). The version is typically displayed in the server output at startup or in the server info endpoint.
    Affected if The version displayed is earlier than 8.0.0, or for Red Hat Keycloak earlier than 7.0.1
  2. Verify REST API accessibility
    Confirm the Keycloak REST API endpoints are network-accessible. This typically involves checking if ports 8080 or 8443 (default Keycloak ports) are listening and reachable from where API clients would connect.
    Affected if The REST API is exposed and reachable by authenticated users
  3. Confirm authentication is enabled
    Verify that Keycloak authentication is required to access the REST API endpoints. Attempt an unauthenticated request to the users endpoint to confirm the server rejects it, then authenticate and retry to confirm access is granted to valid users.
    Affected if Unauthenticated requests are properly rejected but authenticated users can make API calls
  4. Test cross-realm user access
    As an authenticated user in one realm, attempt to query user information in a different realm using the REST API (for example, GET /auth/realms/{other-realm}/users/{target-user-id}) using a known user ID from that other realm.
    Affected if The API returns user information from a realm where the authenticated user has no assignments, confirming the authorization bypass is present

A user is affected if their Keycloak installation version is earlier than 8.0.0 (or Red Hat Keycloak earlier than 7.0.1) AND the REST API is accessible to authenticated users, allowing unauthorized cross-realm user data access.
