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 source supports a browser automation package with caller-directed JavaScript execution. Scanner hints alone do not establish a hidden download-and-execute attack, and the inspected sources show no concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-08T13:15:31.249Z - **Finished:** 2026-10-08T13:15:52.984Z - **Download time:** 1002 ms - **Static scan time:** 970 ms - **AI review time:** 19761 ms - **Total time:** 21735 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 attack was identified in the inspected entrypoint, browser launcher, or runtime excerpts. The flagged dynamic execution is an explicit browser scripting capability. - **Trigger:** A caller starts the CLI and invokes the browser run\_js action with code. - **Impact:** The action can affect the browser page under caller direction; the inspected excerpts do not show covert execution or an unrelated payload. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T13:15:52.984Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime executes supplied code in the active browser page and bounds the returned result and artifacts. - **Rationale:** The source supports a browser automation package with caller-directed JavaScript execution. Scanner hints alone do not establish a hidden download-and-execute attack, and the inspected sources show no concrete malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest lists the matching first-party API package and browser runtime dependencies., Chrome launch is part of the browser launcher and is limited to macOS., Dynamic code execution is exposed through an explicit browser run\_js action that requires caller-provided code., The CLI starts the browser service through its start command. - **Evidence against:** No lifecycle hooks are declared in package.json., The inspected launcher and runtime excerpts show no hidden download-and-execute path. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.194-prod.1791450967742.ge619935c509ea728f45a1d0afd117276a06c01dc. - Review the evidence and your use of @ricsam/r5d-browser@0.0.194-prod.1791450967742.ge619935c509ea728f45a1d0afd117276a06c01dc before allowing it.
