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?

Gold answer

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.'

**Impact**

Exploitation requires write access to a directory that kitabi scans for plugins — by default `~/.config/kitabi/plugins/` or a project-local `.kitabi/plugins/`. In multi-user or CI environments where an untrusted party can write to a shared plugin directory, exploitation is more direct. Effect ranges from path-existence disclosure (via loader error messages) to arbitrary code execution …

Hiroshi,

Confirmed receipt. I've reviewed the loader code at `src/plugin/loader.rs`. You're right — no canonicalization before the join. This is a real issue.

CVSS 7.4 looks correct. Local attack vector, no user interaction, high impact on C and I — accepted as-is.
