Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall script conditionally replaces the CLI shim with a bundled native binary after a version check. Since the CLI delegates execution to native binaries that remain materially unresolved, the package warrants a warning, but the inspected evidence does not establish an attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-25T11:44:27.026Z - **Finished:** 2026-10-25T11:45:47.188Z - **Download time:** 11776 ms - **Static scan time:** 166 ms - **AI review time:** 68218 ms - **Total time:** 80162 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 delegates its main behavior to bundled native programs whose behavior remains substantially unresolved. - **Trigger:** Running the tm command invokes the platform-specific native binary; npm postinstall may replace the JavaScript shim after a version check. - **Impact:** The native program's effects cannot be determined from the available source evidence; no specific harmful effect is established. - **Evidence paths:** .lpm-inspection-RNKxCE/0-30bc712594d9.txt, .lpm-inspection-RNKxCE/1-1672500e295b.txt, .lpm-inspection-RNKxCE/2-2e2aa53a5381.txt, .lpm-inspection-RNKxCE/3-2f3b32e33df6.txt, .lpm-inspection-RNKxCE/4-8f62f80a11c1.txt, .lpm-inspection-RNKxCE/5-2528fc5246c1.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-25T11:45:47.188Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The JavaScript entrypoint passes the caller's arguments to the native program. Available offline analyses could not inspect several binaries and only partially inspected the Windows x64 binary. - **Rationale:** The postinstall script conditionally replaces the CLI shim with a bundled native binary after a version check. Since the CLI delegates execution to native binaries that remain materially unresolved, the package warrants a warning, but the inspected evidence does not establish an attack. - **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:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** High - **Evidence for warning:** package.json declares a postinstall hook; the installer gates it by platform and npm, then stages a native binary and checks it with a version command before replacing the CLI shim., The CLI forwards its arguments to a platform-specific native binary, so its main runtime behavior is outside the JavaScript source., Offline analyses could not inspect the Linux, macOS, Windows ARM64, and Linux x64 binaries; the Windows x64 analysis is partial and leaves call targets uninspected. - **Evidence against:** The inspected installer performs a conditional CLI shim replacement; it does not establish unrelated project or agent configuration changes., No concrete malicious behavior was confirmed in the inspected JavaScript or available artifact analyses. ## Affected versions and remediation This report applies to teammesh@0.30.0. - Review the evidence and your use of teammesh@0.30.0 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: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 78.0% - **Path:** install.js - **Public source:** [View source]() package.json declares a postinstall hook; the installer gates it by platform and npm, then stages a native binary and checks it with a version command before replacing the CLI shim. Public source snippet (untrusted): ```javascript const shim = path.join(__dirname, "bin", "tm.js"); const staged = `${shim}.native`; try { fs.copyFileSync(binary, staged); fs.chmodSync(staged, 0o755); // Only swap in a binary that actually runs here. execFileSync(staged, ["--version"], { stdio: "ignore" }); ``` ### 12. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 78.0% - **Path:** bin/tm.js - **Public source:** [View source]() The CLI forwards its arguments to a platform-specific native binary, so its main runtime behavior is outside the JavaScript source. Public source snippet (untrusted): ```javascript const platform = `${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 ``` ## 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:** 0.30.0 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-10-25T11:41:13.055Z - **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:** 63,545,411 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
