Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.16.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-02T23:57:14.184Z - **Finished:** 2026-10-02T23:59:38.695Z - **Download time:** 1028 ms - **Static scan time:** 2326 ms - **AI review time:** 141156 ms - **Total time:** 144511 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The package can change Claude Code's service endpoint, authentication token, and model settings. This is an authenticated, explicitly activated capability; no confirmed malicious attack was established. - **Trigger:** An authenticated user selects Apply in the dashboard's CLI tool configuration form. - **Impact:** Future Claude Code requests can use the selected endpoint and models, creating an agent configuration capability that warrants a warning under the supplied policy. - **Evidence paths:** src/server/cli-tools/claude.ts, src/server/routes/cli-tools.routes.ts, src/index.ts, src/components/cli-tools/CLIToolConfigForm.tsx - **Review source:** ai\_review - **Reviewed:** 2026-10-02T23:59:38.695Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The request handler forwards supplied settings to the Claude Code configuration writer, which updates the user's settings file. - **Rationale:** Inspected source supports explicit user-activated agent configuration changes, which the supplied policy classifies as warning-only. Package-owned startup registration and daemon management do not establish a malicious install chain. - **Files touched:** ~/.claude/settings.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Claude Code configuration code writes a caller-selected endpoint and token into ~/.claude/settings.json., The dashboard Apply button activates a request handler that passes endpoint, key, and model choices to configuration writers., Dashboard configuration routes require session authentication., The postinstall hook registers package-owned login startup unless KCGRouter\_SKIP\_STARTUP is set. - **Evidence against:** No inspected source established covert exfiltration, remote payload execution, or install-time mutation of foreign agent settings., Agent configuration changes are explicitly activated through the authenticated dashboard. ## Affected versions and remediation This report applies to kcgrouter@0.16.1. - Review the evidence and your use of kcgrouter@0.16.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
