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 lifecycle code performs a platform-gated native binary replacement, and the CLI invokes that binary. Native behavior remains materially unresolved, so the source does not support a clean or malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-23T21:56:26.314Z - **Finished:** 2026-10-23T21:57:15.698Z - **Download time:** 11229 ms - **Static scan time:** 162 ms - **AI review time:** 37993 ms - **Total time:** 49384 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 was established from the inspected JavaScript. The bundled native CLI behavior remains unresolved because several platform binaries could not be inspected and the Windows analysis is incomplete. - **Trigger:** Package installation runs the postinstall version check; invoking tm runs the matching bundled native executable. - **Impact:** Whether the native CLI performs harmful actions cannot be determined from the available inspection. - **Evidence paths:** .lpm-inspection-9kdKDc/1-29a1333a2bf1.txt, .lpm-inspection-9kdKDc/2-4e3019310a12.txt, .lpm-inspection-9kdKDc/3-4f5636051b9c.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-23T21:57:15.698Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer conditionally replaces the JavaScript shim with a native binary, and the shim delegates CLI arguments to that binary. Available native analysis does not resolve its full behavior. - **Rationale:** The inspected lifecycle code performs a platform-gated native binary replacement, and the CLI invokes that binary. Native behavior remains materially unresolved, so the source does not support a clean or malicious verdict. - **Files touched:** package.json, install.js, bin/tm.js - **Network endpoints:** https://api.teammesh.io, https://sync.teammesh.io ### Review decision - **Verdict:** Manual Review - **Confidence:** 91.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json runs install.js as a postinstall hook., The installer runs the staged native binary for a version check, then replaces the CLI shim with it., The CLI shim forwards its arguments to the bundled native binary., The Linux ARM64 and macOS x64 native analyses could not inspect executable behavior., The Windows x64 analysis leaves call targets uninspected; it includes TeamMesh service URLs, whose runtime use is unresolved. ## Affected versions and remediation This report applies to teammesh@0.28.0. - Review the evidence and your use of teammesh@0.28.0 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node install.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node install.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4.

Public source snippet (untrusted): ```text path = native/win32-arm64/tm.exe kind = native_binary sizeBytes = 9307136 magicHex = [redacted] ``` ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 80.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 9. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() package.json runs install.js as a postinstall hook. Public source snippet (untrusted): ```json "postinstall": "node install.js" }, "files": [ "bin", "native", "install.js", "LICENSE" ], "engines": { "node": ">=18" } } ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** install.js - **Public source:** [View source]() The installer runs the staged native binary for a version check, then replaces the CLI shim with it. Public source snippet (untrusted): ```javascript execFileSync(staged, ["--version"], { stdio: "ignore" }); fs.renameSync(staged, shim); } catch { fs.rmSync(staged, { force: true }); } ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** bin/tm.js - **Public source:** [View source]() The CLI shim forwards its arguments to the bundled native binary. Public source snippet (untrusted): ```javascript const result = spawnSync(binary, process.argv.slice(2), { stdio: "inherit" }); if (result.error) { console.error(`tm: ${result.error.message}`); process.exit(1); } if (result.s ``` ### 12.
