CVE-2026-56321 Detail

Description

Capgo (backend Supabase edge functions) before 12.128.2 does not apply the global authentication middleware to the GET /private/role_bindings/:org_id endpoint, unlike the POST and DELETE role_bindings routes, so unauthenticated requests reach the handler instead of being rejected at the middleware layer. The handler still performs its own authorization check and returns Unauthorized, so no direct data exposure occurs; the flaw is inconsistent authentication enforcement across HTTP methods that could enable authorization bypass if the handler logic changes.
