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. Static inspection found a browser automation CLI with expected process and page-script capabilities, but no lifecycle hook or concrete malicious behavior. Local DevTools endpoint validation limits the observed connection surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-22T18:15:59.487Z - **Finished:** 2026-09-22T18:16:59.913Z - **Download time:** 764 ms - **Static scan time:** 343 ms - **AI review time:** 59318 ms - **Total time:** 60426 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 surface was identified. The package provides user-invoked Chrome automation and restricts its DevTools connection to localhost. - **Trigger:** Running the r5d-browser CLI or invoking its browser operations. - **Impact:** No unconsented install-time execution, credential harvesting, exfiltration, or broad persistence was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-22T18:16:59.913Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It launches a configured Chrome executable and communicates through a validated loopback DevTools WebSocket; run\_js operates in the selected browser page. - **Rationale:** Static inspection found a browser automation CLI with expected process and page-script capabilities, but no lifecycle hook or concrete malicious behavior. Local DevTools endpoint validation limits the observed connection surface. - **Network endpoints:** ws://127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a module and CLI entrypoint and contains no lifecycle script., The Chrome launcher rejects DevTools WebSocket URLs unless they are loopback endpoints on the allocated port., Chrome is launched only through the launcher with a resolved executable and constructed argument array., Page JavaScript execution is an explicit run\_js browser operation and is evaluated in the selected page context. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.189-prod.1790099582064.g0c0e53385eca73d6552fbc0c039b446f3d809d80. - Review the evidence and your use of @ricsam/r5d-browser@0.0.189-prod.1790099582064.g0c0e53385eca73d6552fbc0c039b446f3d809d80 before allowing it.
