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-specific native launcher, but the bundled executables are the CLI's main runtime and their behavior remains materially unresolved. This supports manual review, not a finding of malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-18T05:12:58.865Z - **Finished:** 2026-10-18T05:15:02.648Z - **Download time:** 70709 ms - **Static scan time:** 150 ms - **AI review time:** 52924 ms - **Total time:** 123783 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 identified in the inspected JavaScript. The CLI dispatches to bundled native binaries whose behavior could not be fully inspected. - **Trigger:** An eligible npm postinstall stages and checks the matching binary; later, invoking tm runs that binary. - **Impact:** The native program's effects remain unknown because most platform artifacts were unsupported and the Windows x64 analysis was partial. - **Evidence paths:** .lpm-inspection-NhQUYG/0-77f2bdd1182f.txt, .lpm-inspection-NhQUYG/1-c81c735b09b1.txt, .lpm-inspection-NhQUYG/2-6219952131a0.txt, .lpm-inspection-NhQUYG/3-b20bd921d557.txt, .lpm-inspection-NhQUYG/4-ce78a0039dc3.txt, .lpm-inspection-NhQUYG/5-a0741675af9e.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T05:15:02.648Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer replaces bin/tm.js with the native executable after its version check, and the launcher forwards command-line arguments to the native program. - **Rationale:** The inspected JavaScript implements a platform-specific native launcher, but the bundled executables are the CLI's main runtime and their behavior remains materially unresolved. This supports manual review, not a finding of malicious behavior. - **Files touched:** package.json, install.js, bin/tm.js, native/win32-arm64/tm.exe, native/linux-arm64/tm, native/darwin-x64/tm, native/win32-x64/tm.exe, native/darwin-arm64/tm, native/linux-x64/tm ### Review decision - **Verdict:** Manual Review - **Confidence:** 94.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest defines a postinstall hook and maps the tm command to a JavaScript launcher., On eligible npm installs, install.js selects and stages the platform binary, runs it with --version, then replaces the launcher if that succeeds., The launcher passes tm arguments directly to the platform-specific native binary., Host analysis could not inspect most native binaries and reports uninspected call targets in the Windows x64 binary; their runtime behavior remains unresolved. - **Evidence against:** The installer skips Windows and non-npm installs, and removes the staged file if replacement fails. ## Affected versions and remediation This report applies to teammesh@0.8.0. - Review the evidence and your use of teammesh@0.8.0 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.

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 = 6962688 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.

"").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, "b ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** install.js - **Public source:** [View source]() On eligible npm installs, install.js selects and stages the platform binary, runs it with --version, then replaces the launcher if that succeeds. Public source snippet (untrusted): ```javascript 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, sh ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** bin/tm.js - **Public source:** [View source]() The launcher passes tm arguments directly to the platform-specific native binary. 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 r ``` ## 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:** 0.8.0 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-10-18T05:10:16.873Z - **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:** 46,148,818 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
