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:** 0.17.3 - **Selected version is latest:** No - **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. No concrete malicious install or exfiltration chain was found, but the package intentionally provides high-impact agent execution with unattended permission approval. Static analysis coverage was incomplete, so this should be warned rather than marked clean. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 74.0% - **Started:** 2026-09-08T12:07:40.316Z - **Finished:** 2026-09-08T12:09:56.241Z - **Download time:** 1031 ms - **Static scan time:** 642 ms - **AI review time:** 134250 ms - **Total time:** 135925 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:** This is an agent-workflow runner with an inspector that can run local agents and workflows. Routine team sessions auto-approve agent permission choices, and optional sandbox runs expose selected credentials or SSH-agent access to the invoked workflow. - **Trigger:** A user configures or starts a workflow, inspector routine, remote source, MCP server, or sandbox run. - **Impact:** A malicious or unsafe workflow could perform actions available to the configured agent, MCP server, credentials, or SSH agent. - **Evidence paths:** dist/inspector/chat/sessions.js, dist/inspector/runner.js, dist/runner/docker.js, dist/harnesses/codex.js, dist/remote.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T12:09:56.241Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Launches local agent CLIs and workflow-controlled tools with optional automatic approval. - **Rationale:** No concrete malicious install or exfiltration chain was found, but the package intentionally provides high-impact agent execution with unattended permission approval. Static analysis coverage was incomplete, so this should be warned rather than marked clean. - **Files touched:** output/runs/\/runner.json, output/runs/\/runner.log, \/.claude/skills, ~/.claude/skills, \/runner.env ### Review decision - **Verdict:** Suspicious - **Confidence:** 74.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Routine team chats automatically choose an allow permission option before invoking a local agent backend., The inspector launches \`npx kraftwerk run\` detached in the consumer project after a UI-triggered run request., The optional Docker runner forwards selected API-key environment variables and can mount the SSH agent when requested., The Codex harness grants automatic approval when a workflow supplies MCP servers., Remote workflow specifications are cloned from user-supplied Git URLs. - **Evidence against:** package.json has no preinstall, install, or postinstall hook; its only lifecycle script is prepublishOnly., The runtime npm install is limited to building missing inspector assets in a development checkout; published assets are shipped., No source inspected sends harvested credentials or local files to a package-controlled endpoint., The risky operations require an explicit workflow, UI, sandbox, or remote-source action. ## Affected versions and remediation This report applies to @netnodeag/kraftwerk@0.17.3. - Review the evidence and your use of @netnodeag/kraftwerk@0.17.3 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.
