Cap-go capgo.app fails to validate that principals in channel_permission_overrides belong to the organization, allowing authenticated app/org admins to grant channel permissions to non-member users. Attackers with admin privileges can insert override rows with arbitrary external user UUIDs to grant channel-scoped permissions such as channel.promote_bundle to users outside the organization.
