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. The source shows default-on forwarding of saved third-party access tokens to Reason without an affirmative opt-in gate, so warn about conditional credential exposure. The behavior is disclosed and package-aligned, and no install-hook attack is established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 80.0% - **Started:** 2026-10-18T05:35:52.878Z - **Finished:** 2026-10-18T05:38:00.982Z - **Download time:** 4399 ms - **Static scan time:** 573 ms - **AI review time:** 123132 ms - **Total time:** 128104 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 native CLI can forward stored AI-provider access tokens to Reason’s local-subscription service. This occurs at runtime when local logins are enabled, which is the default when the setting is unset. - **Trigger:** A Reason worker starts with local logins enabled and finds usable saved provider credentials. - **Impact:** Third-party provider access tokens are disclosed to Reason’s service during this feature’s operation. The source documents this behavior but does not enforce an affirmative opt-in by default. - **Evidence paths:** .lpm-inspection-KveZNY/0-19b51e9c0166.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T05:38:00.982Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The worker reads credentials from local agent files and keychain sources, then sends provider access tokens to the \`/local-subscription\` route. - **Rationale:** The source shows default-on forwarding of saved third-party access tokens to Reason without an affirmative opt-in gate, so warn about conditional credential exposure. The behavior is disclosed and package-aligned, and no install-hook attack is established. ### Review decision - **Verdict:** Suspicious - **Confidence:** 80.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest identifies a platform-specific CLI package and declares no lifecycle script; the verified token transfer occurs at runtime., The native source defaults local logins on when unset and calls the transfer helper when the worker starts with that setting enabled., The helper reads credentials from local AI tool and keychain sources, then retains provider access tokens for the request., The worker passes collected credentials to its local-subscription client, which sends a request to the \`/local-subscription\` route., The CLI help discloses that local logins are on by default and that Reason receives current access tokens, not refresh tokens., The \`.mcp.json\` match is part of sandbox write protections; it does not show agent configuration mutation. ## Affected versions and remediation This report applies to @reason-machines/cli-darwin-x64@0.2.380. - Review the evidence and your use of @reason-machines/cli-darwin-x64@0.2.380 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.
