CVE-2026-18744

Bypasses share_status; leaks embargoed vendor affected/not-affected + statement text cross-tenant.

MEDIUM 6.5EPSS 0.30%

Does this matter?

Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.

Description

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.
