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. Source inspection did not confirm the scanner’s credential-redirection claim: the inspected authentication helper only resolves the Codex auth-file location. The postinstall downloads companion binaries from project release URLs with pinned hashes, and inspected agent-related writes support session handling rather than broad configuration mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-09T08:52:49.684Z - **Finished:** 2026-10-09T08:53:52.186Z - **Download time:** 759 ms - **Static scan time:** 15541 ms - **AI review time:** 46201 ms - **Total time:** 62502 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 concrete attack surface was identified in the inspected source. The install hook retrieves hash-verified companion binaries, and inspected agent-related code handles local authentication paths and session data. - **Trigger:** Package installation triggers the postinstall script; agent and browser behaviors require their runtime features to be invoked. - **Impact:** No credential theft, broad agent control-surface mutation, or other confirmed attack impact was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T08:53:52.186Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installers retrieve fixed-release binaries and verify their hashes before placing them in the Negotium state directory. Inspected runtime excerpts resolve a Codex auth-file path, write Claude rollout data, and call a localhost browser service. - **Rationale:** Source inspection did not confirm the scanner’s credential-redirection claim: the inspected authentication helper only resolves the Codex auth-file location. The postinstall downloads companion binaries from project release URLs with pinned hashes, and inspected agent-related writes support session handling rather than broad configuration mutation. - **Files touched:** install-browser-rs.mjs, install-bash-rs.mjs, dist/mcp-factories.js, dist/chunk-q2s5f70x.js, dist/registry.js, dist/browser-runtime.js - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/ ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes the CLI and runtime modules; its postinstall invokes two package-owned binary installers., Both installers fetch versioned binaries from the project’s GitHub releases and verify them against platform-specific SHA-256 digests before replacing files under the Negotium state directory., The inspected Codex authentication path resolves to the user’s Codex auth file; the surrounding source shows no credential forwarding to an unrelated gateway., Claude rollout helpers write generated session data beneath Claude’s project directory, while the browser runtime’s inspected request targets a local service and includes its capability header., The inspected query-runtime entry begins with logger setup; no malicious behavior was established from that excerpt. - **Evidence against:** The postinstall performs network downloads and writes executable files, but the inspected installer code limits this to versioned, hash-verified companion binaries in Negotium’s own state directory., Agent-related paths inspected refer to authentication-file resolution and session rollout handling; no unconsented broad agent configuration mutation was established. ## Affected versions and remediation This report applies to negotium@0.18.2. - Review the evidence and your use of negotium@0.18.2 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.
