From 841cd32c660e1781373d4f189f5dc0ff78b46bd6 Mon Sep 17 00:00:00 2001 From: Kjell Tore Guttormsen Date: Sun, 5 Apr 2026 23:58:59 +0200 Subject: [PATCH] feat(security): harden repo with scoped permissions, CVE mapping, and scan evidence MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Settings.json: 16 scoped Bash grants (was 6 wildcards), 26-pattern deny list (was 5). CVE mapping: all 9 OpenClaw CVEs mapped to specific defenses with layer documentation. Scan results: posture Grade D (expected without llm-security), deep scan 0 critical/high. Hooks README: Option A — document llm-security hooks, recommend plugin installation. README: evidence-based security section with scan data and verification instructions.
