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:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 0.2.403 - **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The extracted source shows a default-enabled credential collection and handover path. Because the host analysis is bounded and cannot establish executable reachability or the effective recipient, manual review is warranted rather than a confirmed malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-18T18:36:13.322Z - **Finished:** 2026-10-18T18:40:18.874Z - **Download time:** 4046 ms - **Static scan time:** 585 ms - **AI review time:** 240921 ms - **Total time:** 245552 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:** Embedded source contains a default-enabled path that collects saved AI-service access tokens and passes them to a local-subscription request. The bounded native analysis does not establish that this path is reachable, so no attack is confirmed. - **Trigger:** A worker starts with local logins enabled, which the extracted source shows as the default unless overridden. - **Impact:** If reachable, the path could expose third-party AI-service access tokens to the configured Reason API. - **Evidence paths:** .lpm-inspection-8ZcKqt/0-c53bfc6df9d2.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T18:40:18.874Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The code reads credentials from local stores, keeps access-token fields, and passes them to the Reason client’s local-subscription request; executable reachability and the effective API origin remain unresolved. - **Rationale:** The extracted source shows a default-enabled credential collection and handover path. Because the host analysis is bounded and cannot establish executable reachability or the effective recipient, manual review is warranted rather than a confirmed malicious verdict. ### Review decision - **Verdict:** Manual Review - **Confidence:** 82.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies a macOS ARM64 CLI and contains no lifecycle script declaration., Embedded source defaults local logins on unless overridden and starts credential handover when enabled., The handover code reads credentials from the macOS keychain and agent credential files., The extracted code reduces credentials to access tokens and passes them to a local-subscription request., The flagged sandbox bundle fragment lists agent directories as scan exclusions; its caller uses them in a sandbox deny scan., The offline analysis says its bounded source samples cannot establish whether embedded code is reachable. - **Evidence against:** No install lifecycle hook is declared in the inspected manifest., The flagged bundle location shows sandbox scan exclusions, not an agent configuration write. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-arm64@0.2.403. - Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.403 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.
