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 manifest has no install hook, and the runtime excerpt does not establish an attack. However, the embedded native source indicates default local-login token forwarding, while the inspected executable analysis cannot resolve its recipient, reachability, or other native behavior; manual review is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-18T10:29:14.339Z - **Finished:** 2026-10-18T10:31:54.377Z - **Download time:** 83477 ms - **Static scan time:** 591 ms - **AI review time:** 75969 ms - **Total time:** 160038 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 concrete attack is established by the inspected excerpts. The native executable contains code that appears to forward local login tokens, but its recipient and execution path remain unresolved. - **Trigger:** A running session with local-login forwarding enabled. - **Impact:** The effect on local login tokens cannot be determined from the bounded executable analysis. - **Evidence paths:** .lpm-inspection-6dOsOy/0-5dfa3f05af1a.txt, bin/runtime/srt/sandbox-runtime.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-18T10:31:54.377Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The embedded code invokes a helper to hand over local logins; the inspected source does not reveal the complete transfer path. - **Rationale:** The manifest has no install hook, and the runtime excerpt does not establish an attack. However, the embedded native source indicates default local-login token forwarding, while the inspected executable analysis cannot resolve its recipient, reachability, or other native behavior; manual review is warranted. - **Files touched:** bin/runtime/srt/sandbox-runtime.mjs ### Review decision - **Verdict:** Manual Review - **Confidence:** 82.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json identifies this as a macOS ARM64 native binary package and contains no lifecycle scripts., The embedded analysis shows local-login forwarding enabled by default when unspecified, and a session callback invokes a helper to hand over local logins., The embedded documentation says the feature uses each login's current access token., The executable analysis is explicitly limited: its source windows do not establish loader reachability or rule out other native behavior. - **Evidence against:** The inspected runtime excerpt lists project configuration and command paths but does not show a write or transfer operation., The source excerpts do not establish the recipient or full data flow for local-login forwarding. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-arm64@0.2.393. - Review the evidence and your use of @reason-machines/cli-darwin-arm64@0.2.393 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.
