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
Capgo before 12.128.2 contains an authorization flaw in POST /private/create_device that accepts a caller-supplied org_id parameter without validating it matches the target app's owner organization. Authenticated attackers can create device records for an application using a foreign organization identifier, bypassing the intended org/app authorization boundary.

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

Capgo before 12.128.2 has an authorization bypass in the POST /private/create_device endpoint. The API accepts a user-supplied org_id parameter without validating that it matches the target application's owner organization, allowing authenticated attackers to create device records in applications belonging to other organizations.

MitigationUpgrade to Capgo 12.128.2 or later, which includes proper org_id validation. Alternatively, implement server-side validation to ensure the provided org_id matches the authenticated user's organization or the target app's owner organization before processing the request.

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 Capgo version
    Locate the installed Capgo package or service and retrieve its version number. This may be via package.json, a running service banner, or the application's about/version endpoint.
    Affected if The installed version is earlier than 12.128.2
  2. Verify API endpoint exposure
    Confirm that the POST /private/create_device endpoint is accessible in the Capgo deployment. Check API routing configuration or attempt a test request if authorized.
    Affected if The endpoint is exposed and accepts requests without additional authorization checks beyond authentication
  3. Check org_id parameter handling
    Examine how the create_device endpoint processes the org_id parameter. Review server-side code, API logs, or request handling logic to determine if the supplied org_id is validated against the authenticated user's organization or the target application's owner organization.
    Affected if The endpoint accepts any org_id value without validating ownership or organizational association
  4. Test authorization boundary
    If authorized testing is permitted, send an authenticated request to /private/create_device with an org_id that differs from the authenticated user's organization to see if device creation succeeds for a different organization.
    Affected if Device records can be created for organizations other than the authenticated user's organization

A Capgo deployment is affected if it runs a version earlier than 12.128.2 and the /private/create_device endpoint accepts user-supplied org_id values without validating they match the target application's owner organization.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to Capgo 12.128.2 or later, which includes proper org_id validation. Alternatively, implement server-side validation to ensure the provided org_id matches the authenticated user's organization or the target app's owner organization before processing the request.

Recommended fix High confidence

12.128.2 or later

  1. Confirm current Capgo version in use
  2. Upgrade Capgo to version 12.128.2 or later to resolve the improper authorization vulnerability in POST /private/create_device
