Summary
Any authenticated case participant can fetch any OTHER vendor's CaseStatement + per-vul CaseMemberStatus by supplying that member's id — test_func only checks _is_my_case, not ownership of kwargs['member']. Bypasses share_status; leaks embargoed vendor affected/not-affected + statement text cross-tenant.
