What exact CVSS 3.1 score and full vector string did Hiroshi Nakamura propose for CVE-2026-31418 in his initial disclosure email, and did Lior accept, reject, or modify it?

Hiroshi proposed CVSS 3.1 score 7.4 (High), vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N. Lior accepted it as-is in his reply: 'CVSS 7.4 looks correct. Local attack vector, no user interaction, high impact on C and I — accepted as-is.'
