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 covert exfiltration, lifecycle execution, or foreign AI-agent configuration hijack was found. The package nevertheless ships a persistent arbitrary-shell capability reachable by its agent runtime, so it warrants a warning rather than a clean verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-07-18T20:27:56.000Z - **Finished:** 2026-07-18T20:30:16.298Z - **Download time:** 502 ms - **Static scan time:** 4973 ms - **AI review time:** 134822 ms - **Total time:** 140298 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 intentionally provides an authenticated MCP background-shell service. An agent connected to the service can launch persistent arbitrary shell commands with the runtime environment. - **Trigger:** User starts the Negotium runtime and an authorized agent invokes \`background\_bash\_run\`. - **Impact:** Prompt or agent compromise can execute commands, access inherited environment variables, and modify accessible local files. - **Evidence paths:** package.json, README.md, dist/main.js, dist/cron.js, dist/runtime/src/mcp/background-bash-server.ts, dist/runtime/src/platform/mcp-config.ts - **Review source:** ai\_review - **Reviewed:** 2026-07-18T20:30:16.298Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Authenticated MCP-to-\`bash -c\` persistent command execution. - **Rationale:** No concrete covert exfiltration, lifecycle execution, or foreign AI-agent configuration hijack was found. The package nevertheless ships a persistent arbitrary-shell capability reachable by its agent runtime, so it warrants a warning rather than a clean verdict. - **Files touched:** dist/main.js, dist/cron.js, dist/runtime/src/mcp/background-bash-server.ts - **Network endpoints:** https://api.deepseek.com/v1/chat/completions, http://127.0.0.1:${port}/mcp, http://127.0.0.1:${port}/sse ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** \`dist/runtime/src/mcp/background-bash-server.ts\` executes MCP-supplied strings with \`bash -c\`., The background shell inherits \`process.env\` and accepts an optional arbitrary \`cwd\`., Background commands are detached and persist beyond an agent turn; output is injected into a session inbox., \`dist/cron.js\` includes a configurable DeepSeek completion endpoint. - **Evidence against:** \`package.json\` has no preinstall, install, or postinstall lifecycle hook., \`dist/main.js\` dispatches runtime actions only through explicit CLI commands such as \`init\` and \`serve\`., Background-bash startup requires per-runtime capability values and exposes local HTTP MCP endpoints., No inspected source writes foreign Codex/Claude MCP configuration or sends credentials to an untrusted endpoint. ## Affected versions and remediation This report applies to negotium@0.1.16. - Review the evidence and your use of negotium@0.1.16 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.
