Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The inspected source supports a benign embedded browser SDK: its fixed POST sends telemetry to the package’s own API and omits ambient cookies. The password-related match is only an input-kind label, and no malicious install behavior or unrelated credential transfer was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-14T02:51:55.987Z - **Finished:** 2026-10-14T02:54:15.486Z - **Download time:** 1034 ms - **Static scan time:** 3419 ms - **AI review time:** 135045 ms - **Total time:** 139499 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 malicious attack was identified. The fixed POST is the browser SDK’s telemetry transport to its package API. - **Trigger:** The embedded SDK records an allowed event and flushes a batch. - **Impact:** The API receives product telemetry. The inspected source does not establish secret theft or an unrelated credential transfer. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T02:54:15.486Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It sends event batches to the package API using its configured token; the request omits ambient browser credentials. Limited measurement is possible under the source’s separate measurement gate. - **Rationale:** The inspected source supports a benign embedded browser SDK: its fixed POST sends telemetry to the package’s own API and omits ambient cookies. The password-related match is only an input-kind label, and no malicious install behavior or unrelated credential transfer was identified. - **Files touched:** package.json, dist/index.cjs, dist/index.js, dist/chat-XX5QSQOG.js, dist/chunk-NKFEZTTN.js - **Network endpoints:** https://api.arcyai.com/api/v1/sdk/telemetry, https://api.arcyai.com/api/v1/sdk/measurement ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest selects the bundled CommonJS and ESM entrypoints and declares a prepublishOnly build script., The fixed POST endpoint belongs to the SDK telemetry transport and uses the package’s API host., Telemetry batches use the configured token and omit ambient browser credentials., Full telemetry requires a recorded grant; limited measurements are separately gated and restricted to an event allowlist., The password-related scanner match is an input-kind label, not credential material., The ESM entrypoint and chat bundle import package-local components consistent with an embedded SDK. ## Affected versions and remediation This report applies to arcy.js@0.2.5. - Review the evidence and your use of arcy.js@0.2.5 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.
