Organization enumeration via distinguishable RPC errors
Published Jun 30, 2026 · Updated Jun 30, 2026
Information disclosure in Capgo before 12.128.2 allows remote attackers to enumerate organizations through a public Supabase RPC. The SECURITY DEFINER public.invite_user_to_org function accepts calls made with a publishable key and returns NO_ORG for nonexistent identifiers but NO_RIGHTS for existing ones. No authenticated session or user interaction is required, and the demonstrated consequence is limited to disclosing whether an organization identifier exists.
