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 executable analysis reveals a concerning candidate credential-forwarding path with a default-enabled caller, but its bounded source windows do not establish reachability or the recipient. Manual review is needed to resolve those material facts; the agent-related JavaScript location is only used to exclude those directories from file searches. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-19T20:44:00.855Z - **Finished:** 2026-10-19T20:45:42.545Z - **Download time:** 14659 ms - **Static scan time:** 593 ms - **AI review time:** 86437 ms - **Total time:** 101690 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 bounded analysis of the shipped executable contains candidate code that gathers local AI-service credentials and sends access credentials to a local-subscription endpoint. The analysis does not establish that this code is reachable in the executable. - **Trigger:** The candidate caller starts when local login sharing is enabled; the inspected fallback enables it by default. - **Impact:** If reachable, this could disclose third-party service credentials to the configured API recipient. The recipient and executable reachability remain unresolved. - **Evidence paths:** .lpm-inspection-8Kv44T/0-9b10715fe0db.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-19T20:45:42.545Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Candidate code reads credentials from environment variables and local credential stores, then submits discovered access credentials through an authenticated local-subscription request using the worker API origin. - **Rationale:** The executable analysis reveals a concerning candidate credential-forwarding path with a default-enabled caller, but its bounded source windows do not establish reachability or the recipient. Manual review is needed to resolve those material facts; the agent-related JavaScript location is only used to exclude those directories from file searches. ### Review decision - **Verdict:** Manual Review - **Confidence:** 93.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies the requested package and version., Bounded executable analysis contains candidate code that collects third-party credentials from environment variables and local credential stores., Candidate code repeatedly submits discovered access credentials through an authenticated local-subscription request using the worker API origin., The credential-forwarding path is enabled when local login sharing is true, and the inspected configuration fallback sets it to true by default., The offline executable analysis explicitly says its bounded source windows do not establish whether the candidate code is reachable., The flagged agent-related location lists command and agent directories that the sandbox runtime excludes from a file-search command. - **Evidence against:** The manifest has no lifecycle scripts, and the inspected JavaScript bundle contains sandbox-runtime behavior rather than a demonstrated credential-transfer caller., The candidate credential-transfer code has a boolean setting that can disable it, but the inspected fallback enables it by default. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-x64@0.2.451. - Review the evidence and your use of @reason-machines/cli-win32-x64@0.2.451 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.
