Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected JavaScript shows a conditional postinstall shim replacement and CLI forwarding, with no confirmed attack behavior. Material native binary behavior remains unresolved, requiring manual review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-26T11:11:19.350Z - **Finished:** 2026-10-26T11:12:02.868Z - **Download time:** 5617 ms - **Static scan time:** 167 ms - **AI review time:** 37734 ms - **Total time:** 43518 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 confirmed in the inspected JavaScript. The native CLI binaries remain materially unresolved, so their behavior cannot be cleared. - **Trigger:** Installing the package triggers its postinstall hook; running the CLI invokes the platform binary. - **Impact:** The inspected installer behavior is limited to the package CLI, but unresolved native behavior prevents a reliable package-wide verdict. - **Evidence paths:** .lpm-inspection-Taq4Tj/0-1d3df8f4098e.txt, .lpm-inspection-Taq4Tj/4-569226271687.txt, .lpm-inspection-Taq4Tj/5-f57b2b986b49.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-26T11:12:02.868Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook may replace the CLI shim with a native binary after a version check. Offline analysis could not inspect most binaries and left part of the Windows x64 call graph unreviewed. - **Rationale:** The inspected JavaScript shows a conditional postinstall shim replacement and CLI forwarding, with no confirmed attack behavior. Material native binary behavior remains unresolved, requiring manual review. - **Files touched:** package.json, install.js, bin/tm.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 95.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json runs install.js from a postinstall hook., install.js conditionally stages the platform binary and runs it with --version before replacing the CLI shim., bin/tm.js forwards CLI arguments to the platform binary., Offline analysis could not inspect several native binaries; the Windows x64 analysis also leaves call targets uninspected. - **Evidence against:** The install hook exits on Windows and when the npm user agent check fails., The inspected JavaScript shows a CLI shim replacement and argument forwarding, but no confirmed attack behavior. ## Affected versions and remediation This report applies to teammesh@0.30.1. - Review the evidence and your use of teammesh@0.30.1 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.
