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 allowing organizations to manage their cyber threat intelligence knowledge and observables. Due to lack of certain security controls on the profile edit functionality, an authenticated attacker with low privileges can gain administrative privileges on the web application.

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 · moderate confidence

OpenCTI suffers from an IDOR (Insecure Direct Object Reference) or broken access control vulnerability in its profile edit functionality. An authenticated user with low-level privileges can manipulate their profile to gain administrative access to the web application due to missing or insufficient authorization checks on the profile modification endpoint.

MitigationImplement proper role-based access control (RBAC) and authorization validation on all profile edit endpoints to ensure users cannot escalate privileges beyond their assigned role; enforce server-side validation that low-privilege users cannot modify role/permission attributes.

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 OpenCTI installation and version
    Locate the OpenCTI application and determine its installed version number by checking the application's about page, package manifest, or version file provided by the software
    Affected if The installed version is 5.12.31 or lower
  2. Verify user role configuration
    Access the OpenCTI administration panel and review the roles assigned to standard or low-privilege user accounts to confirm the role hierarchy
    Affected if Low-privilege users have accounts with modifiable role attributes in the system
  3. Examine profile modification endpoint
    Using an authenticated low-privilege user session, inspect the HTTP requests and responses when accessing the profile edit functionality; check if role or permission fields are present in the profile modification form or API payload
    Affected if The profile edit endpoint exposes role or permission fields that can be manipulated by low-privilege users
  4. Test for privilege escalation
    As a low-privilege user, attempt to modify the profile request to include administrative role parameters or elevated permission values, then observe whether the system accepts the modification
    Affected if The system allows a low-privilege user to successfully change their own role to administrator through profile modification

A user is affected if they are running OpenCTI version 5.12.31 or lower AND the profile edit functionality permits low-privilege users to modify role attributes, allowing unauthorized privilege escalation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 5.12.31
Interim mitigation

Implement proper role-based access control (RBAC) and authorization validation on all profile edit endpoints to ensure users cannot escalate privileges beyond their assigned role; enforce server-side validation that low-privilege users cannot modify role/permission attributes.

Recommended fix Moderate confidence

OpenCTI version 5.12.32 or later

  1. 1. Back up your current OpenCTI installation and database
  2. 2. Verify your current version is <= 5.12.31 by checking the OpenCTI platform or docker-compose.yml
  3. 3. Update OpenCTI to version 5.12.32 or later using your deployment method (docker-compose update, helm upgrade, etc.)
  4. 4. After update, verify the new version is running: docker ps or check the UI footer
  5. 5. Test that the profile edit functionality now properly enforces authorization controls
  6. 6. Confirm low-privilege users can no longer escalate to administrative privileges
