"descriptions": [
{
"lang": "en",
"value": "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."
