CVE-2026-56246
Capgo - Cross-Organization Authorization Bypass via Scoped API Key Privilege Inheritance
Description

Capgo before 12.128.2 contains a broken access control vulnerability in the organization management API where a scoped API key (limited_to_orgs) inherits its owner-user's permissions, allowing destructive cross-organization actions. When a user is an admin in two organizations and creates a write-mode API key restricted to one organization, that key can still perform destructive operations (e.g., DELETE /organization, DELETE /organization/members) against another organization. The root cause is route-level authorization (rbac_check_permission_direct) that evaluates the key owner's user privileges before enforcing the API key's limited_to_orgs scope.

Solution
Address broken access control in the organization management API by correctly enforcing API key scopes.
  • Update Capgo to version 12.128.2 or later.
  • Ensure API key scopes are strictly enforced.
  • Validate RBAC checks against key restrictions.
  • Test cross-organization permission handling.
