CyberRota Analysis
AI-GeneratedThe capgo npm package, up to version 12.207.1, contains a vulnerability in the validateInvite() function that allows authenticated users with limited permissions to invite external users with elevated roles, such as org_admin or org_billing_admin. This flaw can lead to privilege escalation, granting unauthorized administrative control over the organization's resources and billing. Organizations using this package should prioritize remediation, especially those with sensitive data or critical operations reliant on proper role management.

Original NVD Description
capgo.app (npm package `capgo`) through version 12.207.1 does not compare the caller's role rank against the requested role in the validateInvite() function of supabase/functions/_backend/private/invite_new_user_to_org.ts. The POST /private/invite_new_user_to_org endpoint only requires the org.update_user_roles permission for org_super_admin invitations, so an authenticated user holding only the org.invite_user permission (e.g., an org_member) can invite an external user as org_admin or org_billing_admin. When the invited account accepts the invitation via POST /private/accept_invitation, ensureOrgMembership creates the role binding using the Supabase service-role key, which bypasses the prevent_role_binding_priority_escalation and check_org_user_privileges database triggers. This allows privilege escalation resulting in full administrative control over the organization's apps, channels, members, and billing. The issue is addressed by pull request #3096, which compares the inviter's rank before permitting elevated invitations.
