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. This is a concrete conditional forwarding capability with an unrestricted operator-configured destination, but it has no automatic install trigger and requires configuration. It warrants a warning rather than a publication block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-26T04:46:14.457Z - **Finished:** 2026-09-26T04:47:16.079Z - **Download time:** 503 ms - **Static scan time:** 1074 ms - **AI review time:** 60045 ms - **Total time:** 61622 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 running browser agent can forward recruitment-message data to a default remote host. Its destination may be overridden through environment configuration, while its token is sent as an authorization header. - **Trigger:** Starting the package entrypoint and processing qualifying browser recruitment events with the required environment settings. - **Impact:** Candidate data and the configured API token can be exposed to an operator-selected endpoint; no install-time attack was identified. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T04:47:16.079Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Event tracking constructs a payload from browser data and posts it with the configured token to the selected API base URL. - **Rationale:** This is a concrete conditional forwarding capability with an unrestricted operator-configured destination, but it has no automatic install trigger and requires configuration. It warrants a warning rather than a publication block. - **Network endpoints:** https://huajune.duliday.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The active entrypoint enables recruitment-event tracking unless disabled and permits an environment-selected API base URL., When configured, tracking sends an environment token and event body in an HTTP POST request., Browser message events include candidate names, message previews, and conversation identifiers. - **Evidence against:** The manifest has no preinstall, install, or postinstall lifecycle hook., The remote request requires both a token and an agent identifier before it runs. ## Affected versions and remediation This report applies to @roll-agent/browser-use-agent@0.27.0. - Review the evidence and your use of @roll-agent/browser-use-agent@0.27.0 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.
