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 substantiate the scanner's credential-redirect claim: the cited auth helpers select the configured or standard Codex auth path, and the inspected rollout code writes session files locally. The install hook downloads package-aligned binaries, with the browser installer enforcing a pinned SHA-256 digest, so the available evidence supports clean. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 85.0% - **Started:** 2026-10-09T08:52:04.138Z - **Finished:** 2026-10-09T08:53:07.106Z - **Download time:** 506 ms - **Static scan time:** 15263 ms - **AI review time:** 47198 ms - **Total time:** 62968 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 flagged locations. The postinstall downloads package-aligned release binaries, and the browser installer checks the downloaded bytes against a pinned digest. - **Trigger:** npm postinstall downloads the supported platform binaries; the CLI and exported runtime code run when invoked by a user. - **Impact:** The inspected source supports ordinary runtime setup and session handling; it does not establish credential theft or agent-control hijacking. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T08:53:07.106Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The flagged auth-path code resolves a Codex auth file, while the rollout locations write Claude session data beneath the user's home directory. The inspected excerpts do not show those credentials being redirected to an unrelated recipient. - **Rationale:** Source inspection did not substantiate the scanner's credential-redirect claim: the cited auth helpers select the configured or standard Codex auth path, and the inspected rollout code writes session files locally. The install hook downloads package-aligned binaries, with the browser installer enforcing a pinned SHA-256 digest, so the available evidence supports clean. - **Files touched:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/agent-helpers.js, dist/chunk-v18s6bj4.js, dist/chunk-yf3nnkc1.js, dist/hosted-agent.js, dist/main.js, dist/mcp-factories.js, dist/registry.js, dist/runtime/src/platform/config.ts, dist/query-runtime.js, dist/browser-runtime.js - **Network endpoints:** https://github.com/maestrojeong/browser-rs-mcp/releases/download/ ### Review decision - **Verdict:** Clean - **Confidence:** 85.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a CLI and defines a postinstall that runs two package-owned installer scripts., The browser installer downloads a release asset and rejects it if its SHA-256 digest differs from the pinned value., The Codex auth path references the caller's configured auth file or the standard CODEX\_HOME auth file., The flagged source locations in agent-helpers.js, chunk-yf3nnkc1.js, hosted-agent.js, main.js, mcp-factories.js, and config.ts resolve the same Codex auth-file path helper., The flagged chunk-v18s6bj4.js and registry.js locations write Claude rollout/session files under the caller's home directory., The browser-runtime.js and query-runtime.js entry excerpts show bundled runtime imports; these excerpts do not establish a malicious behavior. - **Evidence against:** The inspected postinstall installers fetch platform-specific binaries from the package's GitHub release and verify the browser binary against a pinned digest., The inspected source does not show the flagged auth-path helper sending credentials to an unofficial gateway or persisting a credential redirect. ## Affected versions and remediation This report applies to negotium@0.16.3. - Review the evidence and your use of negotium@0.16.3 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.
