Capgo before 12.128.2 contains a NULL-auth bypass vulnerability in the public.get_org_user_access_rbac function that allows unauthenticated attackers to retrieve RBAC role bindings and member email addresses. Attackers can exploit improper NULL comparison in the authorization gate to disclose organization membership, roles, and email addresses via the PostgREST RPC endpoint using only a public API key.
