Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.6.1 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Install metadata has no lifecycle scripts, and the only runtime network client sends the operator-provided token to the operator-provided APP\_URL. Bundled Electron and vm script execution are unused or product-aligned and do not form a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-26T07:17:14.975Z - **Finished:** 2026-09-26T07:18:40.295Z - **Download time:** 772 ms - **Static scan time:** 4990 ms - **AI review time:** 79558 ms - **Total time:** 85320 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:** No attack was identified. The package is a user-started private API runner that talks only to the APP\_URL the operator sets and sends the token the operator supplies for that host. - **Trigger:** The user executes the api-spector-agent bin with APP\_URL and AGENT\_TOKEN or RUNTIME\_TOKEN set. There is no install-time hook. - **Impact:** Traffic and credentials stay on the caller-chosen cloud. No unconsented exfiltration, persistence, or agent control-surface write was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-26T07:18:40.295Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** main polls APP\_URL/api/monitor-runtime/due with the caller token and posts each check result to APP\_URL/api/monitor-runtime/{id}/result. - **Rationale:** Install metadata has no lifecycle scripts, and the only runtime network client sends the operator-provided token to the operator-provided APP\_URL. Bundled Electron and vm script execution are unused or product-aligned and do not form a concrete attack. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json publishes a CLI named api-spector-agent whose bin and main are dist/index.cjs, with no preinstall, install, or postinstall scripts., The agent reads APP\_URL, AGENT\_TOKEN, and optional RUNTIME\_TOKEN from the process environment and refuses to start unless a URL and a token are present., Bearer or runtime-token headers are attached only to fetch calls under that caller-supplied APP\_URL for the due-monitor feed and result posts. - **Evidence against:** A bundled copy of Electron's installer uses spawnSync on install.js, but that path runs only when an in-memory secret store entry exists, and nothing in this package writes that store., Due checks can run pre/post scripts in a vm sandbox; that matches the documented private-runner product and is activated only after the user starts the agent against their own cloud. ## Affected versions and remediation This report applies to @testsmith/api-spector-agent@0.6.1. - Review the evidence and your use of @testsmith/api-spector-agent@0.6.1 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.
