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 implements a platform-gated shim replacement and forwards CLI arguments to bundled native executables. Their runtime behavior remains materially unresolved, so the source does not support a malicious verdict or a clean assessment. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-18T00:55:45.310Z - **Finished:** 2026-10-18T00:56:27.948Z - **Download time:** 2794 ms - **Static scan time:** 140 ms - **AI review time:** 39703 ms - **Total time:** 42638 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:** The CLI runs bundled native executables whose behavior could not be resolved from the available offline analysis. No attack was identified in the inspected JavaScript sources. - **Trigger:** Running tm invokes the executable for the current platform; npm postinstall may also run its --version check on supported platforms. - **Impact:** The native CLI's effects remain undetermined; the inspected source does not establish malicious behavior. - **Evidence paths:** .lpm-inspection-tM3ZTo/0-fb94abb33d98.txt, .lpm-inspection-tM3ZTo/1-12a29726d541.txt, .lpm-inspection-tM3ZTo/2-e285c6cb0cd0.txt, .lpm-inspection-tM3ZTo/3-41faa0ce0abd.txt, .lpm-inspection-tM3ZTo/4-598fcaf03a94.txt, .lpm-inspection-tM3ZTo/5-dea4677d4c7f.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T00:56:27.948Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The JavaScript CLI forwards the user's arguments to the native executable. Analysis could not establish what most bundled executables do, and the Windows x64 analysis is incomplete. - **Rationale:** The inspected JavaScript implements a platform-gated shim replacement and forwards CLI arguments to bundled native executables. Their runtime behavior remains materially unresolved, so the source does not support a malicious verdict or a clean assessment. - **Files touched:** package.json, install.js, bin/tm.js, native/linux-arm64/tm, native/linux-x64/tm, native/darwin-arm64/tm, native/darwin-x64/tm, native/win32-arm64/tm.exe, native/win32-x64/tm.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 93.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json declares a postinstall hook and maps the tm command to bin/tm.js., The install hook is gated to npm on non-Windows platforms and requires a matching bundled binary., The hook runs the staged binary with --version before replacing the JavaScript shim., The CLI launches the platform binary and passes it the user's arguments., Offline reports leave the Linux and macOS binaries unsupported; the Windows x64 report has uninspected call targets and other Windows binaries are unsupported. - **Evidence against:** The inspected install hook only performs a platform-specific shim replacement after checking that the staged binary runs. ## Affected versions and remediation This report applies to teammesh@0.3.1. - Review the evidence and your use of teammesh@0.3.1 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. 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. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Medium: Ships Native Binary - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** native/win32-arm64/tm.exe - **Public source:** [View source]() Package ships native binary artifacts. Public source snippet (untrusted): ```text path = native/win32-arm64/tm.exe kind = native_binary sizeBytes = 6614016 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:** 93.0% - **Path:** package.json - **Public source:** [View source]() package.json declares a postinstall hook and maps the tm command to bin/tm.js. Public source snippet (untrusted): ```json "bin": { "tm": "bin/tm.js" }, "scripts": { "postinstall": "node install.js" }, "files": ``` ### 10. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 93.0% - **Path:** install.js - **Public source:** [View source]() The install hook is gated to npm on non-Windows platforms and requires a matching bundled binary. Public source snippet (untrusted): ```javascript if (process.platform === "win32") process.exit(0); if (!(process.env.npm[redacted] ?? "").startsWith("npm/")) process.exit(0); const binary = path.join(__dirname, "native", `${process.platform}-${process.arch}`, "tm"); if (!fs.existsSync(binary)) process.exit(0); const shim = path.join(__dirname, "bin", "tm ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 93.0% - **Path:** install.js - **Public source:** [View source]() The hook runs the staged binary with --version before replacing the JavaScript shim. Public source snippet (untrusted): ```javascript const shim = path.join(__dirname, "bin", "tm.js"); const staged = `${shim}.native`; try { fs.copyFileSync(binary, staged); fs.chmodSync(staged, 0o755); // Only swap in a binary that actually runs here. execFileSync(staged, ["--version"], { stdio: "ignore" }); fs.renameSync(staged, shim); } catch { fs.rmSync(staged, ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 93.0% - **Path:** bin/tm.js - **Public source:** [View source]() The CLI launches the platform binary and passes it the user's arguments. Public source snippet (untrusted): ```javascript const platform = `${process.platform}-${process.arch}`; const binary = path.join(__dirname, "..", "native", platform, process.platform === "win32" ? "tm.exe" : "tm"); if (!fs.existsSync(binary)) { console.error(`tm: no prebuilt binary for ${platform}`); process.exit(1); } const result = spawnSync(binary, process.argv.slice(2), { stdio: "inherit" }); if (result.error) { console.error(`tm ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** teammesh - **Ecosystem:** npm - **Version:** 0.3.1 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-10-18T00:52:34.689Z - **Package first seen:** 2026-10-16T15:07:14.061Z - **Package last seen:** 2026-11-04T20:01:36.217Z - **Known versions:** 70 - **Latest version:** 0.49.1 - **Appeal under review:** No - **Description:** TeamMesh CLI: connects AI coding agents to your team - **Maintainers:** hassaans - **Runtime engines:** node: \>=18 - **Artifact files:** 10 - **Artifact unpacked size:** 43,811,530 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
