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
OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to 6.9.7, an organization admin can escalate their privileges by adding a user from a different organization with higher privileges, to their own organization. This is due to incorrect ACL on userEdit relationAdd. This vulnerability is fixed in 6.9.7.

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

In OpenCTI prior to 6.9.7, an organization admin can escalate their privileges by adding a user from a different organization with higher privileges to their own organization. This occurs due to incorrect Access Control List (ACL) enforcement on the userEdit relationAdd function, allowing cross-organization privilege escalation.

MitigationUpgrade to OpenCTI version 6.9.7 or later. Until then, restrict organization admin permissions and monitor for unauthorized user organization assignments.

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. Check installed OpenCTI version
    Access the OpenCTI admin interface and navigate to Settings > About, or run 'docker ps' to check the container version tag, or inspect the API version endpoint
    Affected if The installed version is earlier than 6.9.7 (e.g., 6.9.6, 6.9.5, etc.)
  2. Verify organization admin role is in use
    Navigate to Settings > Users and Organizations > Organizations. Review the list of organizations and identify if any have users assigned the 'Organization Admin' role
    Affected if One or more organizations have users with Organization Admin privileges, creating potential targets for this ACL bypass
  3. Audit cross-organization user memberships
    Query the users list and examine the 'organizations' field for each user. Specifically check if any user from Organization A is also a member of Organization B with elevated roles
    Affected if Any user belongs to multiple organizations, particularly if they hold higher-privilege roles (like Admin) in one organization while being added to another by an Organization Admin
  4. Review userEdit relationAdd ACL permissions
    Inspect the OpenCTI backend logs or API configuration for the userEdit mutation and relationAdd function. Check if Organization Admins can invoke this function on users outside their own organization
    Affected if The ACL configuration permits Organization Admins to call relationAdd on users from different organizations, allowing unauthorized cross-org user assignment

You are affected if running OpenCTI version below 6.9.7 and your platform has Organization Admins with the ability to add users from other organizations to their own organization.
