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. Source inspection found conditional forwarding of saved third-party access tokens to the configured Reason API, enabled by default in a configuration path. The feature is disclosed and switchable, but the source does not establish recipient-specific consent for forwarding those credentials. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-19T08:26:45.324Z - **Finished:** 2026-10-19T08:28:37.780Z - **Download time:** 18858 ms - **Static scan time:** 600 ms - **AI review time:** 92997 ms - **Total time:** 112456 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 embedded CLI contains a path that forwards saved third-party login access tokens to the Reason API. Its default configuration enables this local-login feature in some connection flows. - **Trigger:** A Reason local worker starts with local logins enabled; the setting defaults on when no API key is supplied. - **Impact:** Reason receives current third-party access tokens, creating conditional exposure of those accounts to the configured Reason API. - **Evidence paths:** .lpm-inspection-FI0zoB/0-4b0ba2170c93.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-19T08:28:37.780Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI reads local provider credential stores and submits discovered logins through the device-authenticated local-subscription endpoint. - **Rationale:** Source inspection found conditional forwarding of saved third-party access tokens to the configured Reason API, enabled by default in a configuration path. The feature is disclosed and switchable, but the source does not establish recipient-specific consent for forwarding those credentials. - **Files touched:** .lpm-inspection-FI0zoB/0-4b0ba2170c93.txt, bin/reason.exe - **Network endpoints:** /local-subscription on the configured Reason API ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest identifies this as a platform-specific native Reason CLI package., The flagged sandbox runtime lists protected agent configuration locations; the inspected excerpt shows no configuration write., Embedded executable source reads saved local-login credentials, including Claude credentials and provider auth files., The executable defines a device-authenticated \`/local-subscription\` endpoint and calls it with each discovered provider login., A running worker hands local logins to that endpoint when \`localLogins\` is enabled; configuration defaults that option on unless an API key is supplied., The CLI help says Reason receives each login's current access token and offers an off setting. - **Evidence against:** The transfer is tied to the product’s local-login feature, is disclosed in its CLI help, excludes refresh tokens, and can be disabled., The inspected source does not establish credential misuse beyond forwarding tokens to the configured Reason API. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-arm64@0.2.434. - Review the evidence and your use of @reason-machines/cli-win32-arm64@0.2.434 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.
