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. No concrete malicious chain was found, but automatic postinstall staging of a remote native payload is a meaningful unresolved supply-chain risk. The observed Claude/Codex session writes are runtime helpers, not lifecycle-triggered control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-07-28T18:45:08.341Z - **Finished:** 2026-07-28T18:45:50.634Z - **Download time:** 765 ms - **Static scan time:** 7217 ms - **AI review time:** 34311 ms - **Total time:** 42293 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:** npm postinstall fetches a version-pinned Browser.rs binary and stores it in the package state directory. The binary is not executed by the installer. - **Trigger:** npm installation (postinstall) - **Impact:** A compromised pinned release or hash update could stage executable code for later runtime use. - **Evidence paths:** package.json, install-browser-rs.mjs, dist/chunk-1p2n47qd.js, dist/agent-helpers.js - **Review source:** ai\_review - **Reviewed:** 2026-07-28T18:45:50.634Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** verified remote native-binary staging - **Rationale:** No concrete malicious chain was found, but automatic postinstall staging of a remote native payload is a meaningful unresolved supply-chain risk. The observed Claude/Codex session writes are runtime helpers, not lifecycle-triggered control-surface mutation. - **Files touched:** install-browser-rs.mjs, ~/.negotium/bin/browser-rs/v0.1.12/browser-rs - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/v0.1.12 ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs postinstall, install-browser-rs.mjs downloads a native executable, Downloaded binary is saved executable under ~/.negotium - **Evidence against:** Download URL and SHA-256 are hard-coded, Installer verifies hash before rename, No credential harvesting or foreign agent-config write found ## Affected versions and remediation This report applies to negotium@0.1.32. - Review the evidence and your use of negotium@0.1.32 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.
