CVE-2026-56222
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 · uneditedCapgo before 12.128.2 contains an authorization bypass vulnerability in POST /private/role_bindings that fails to verify app_id ownership during app-scoped role binding creation. An attacker with administrative privileges in one organization can create role bindings targeting applications owned by other organizations, enabling unauthorized read and modification of victim applications.
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 confidenceCapgo before 12.128.2 has an authorization bypass in the POST /private/role_bindings endpoint that does not verify app_id ownership when creating app-scoped role bindings. An attacker with admin privileges in one organization can create role bindings for applications owned by other organizations, allowing unauthorized read and modification of victim applications.

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 checksWork through these to decide whether this CVE applies to you.
-
Check Capgo versionAccess the Capgo admin dashboard or use the CLI/API to query the installed version (often available via /api/version endpoint, admin settings page, or package.json if self-hosted)Affected if The installed version is below 12.128.2 (e.g., 12.128.1, 12.127.x, or earlier)
-
Verify role_bindings endpoint accessibilitySend a POST request to /private/role_bindings with valid admin credentials and inspect whether the request succeeds without additional app_id ownership validationAffected if The endpoint accepts requests without verifying that the authenticated organization owns the referenced app_id
-
Inspect existing role bindings for cross-organization app referencesQuery the role_bindings API or database table to list all role bindings; check the app_id field in each binding and compare the organization ID associated with each binding to the organization that owns the referenced appAffected if Any role binding exists where the app_id belongs to a different organization than the binding's owner organization
-
Review audit logs for suspicious role binding creationExamine Capgo audit logs or access logs for POST requests to /private/role_bindings that create bindings with app_ids from organizations other than the requester's organizationAffected if Logs show role bindings created for apps owned by other organizations by a user who should not have access to those apps
You are affected if your Capgo version is below 12.128.2 AND your organization has users with admin privileges who could potentially create unauthorized cross-organization role bindings.

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 · scopedUpgrade Capgo to version 12.128.2 or later which includes proper app_id ownership verification in the role_bindings endpoint.
Capgo version 12.128.2 or later
- 1. Identify the current Capgo installation version by checking the application or deployment configuration
- 2. Review the application's dependency management system (package.json, Gemfile, requirements.txt, etc.) to locate the Capgo package version
- 3. Update the Capgo package dependency to version 12.128.2 or later in your dependency manifest
- 4. Run the dependency update command appropriate to your package manager (e.g., npm update, pip install -U, bundle update)
- 5. Verify the new version is installed: check the lock file or run a version query command
- 6. Test the application functionality, specifically: verify that POST /private/role_bindings now correctly validates app_id ownership
- 7. Deploy the updated application to your staging environment and conduct security testing to confirm the authorization bypass is fixed
- 8. Deploy to production after successful validation
