Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The install hook’s readable behavior is limited to a platform-specific shim replacement after a successful version check, with a conditional upgrade notice. The bundled native CLI is only partially inspectable, but the available evidence does not establish malicious behavior and its service host strings fit the package’s stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 83.0% - **Started:** 2026-11-03T22:13:02.078Z - **Finished:** 2026-11-03T22:14:20.946Z - **Download time:** 4114 ms - **Static scan time:** 161 ms - **AI review time:** 74592 ms - **Total time:** 78868 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 identified; the install hook performs a guarded local CLI shim replacement and the command delegates to a bundled native CLI. - **Trigger:** The postinstall hook runs during installation; the native CLI runs when the user invokes tm. - **Impact:** The reviewed JavaScript shows local file changes and no collection or transmission of user or project data. Native runtime behavior could not be fully inspected. - **Review source:** ai\_review - **Reviewed:** 2026-11-03T22:14:20.946Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook selects the platform binary, checks it with --version, and swaps it into the shim. It then conditionally requests a pool-manager upgrade notice. - **Rationale:** The install hook’s readable behavior is limited to a platform-specific shim replacement after a successful version check, with a conditional upgrade notice. The bundled native CLI is only partially inspectable, but the available evidence does not establish malicious behavior and its service host strings fit the package’s stated purpose. - **Files touched:** bin/tm.js, bin/tm.js.native - **Network endpoints:** api.teammesh.io, sync.teammesh.io, o4512288884326400.ingest.us.sentry.io ### Review decision - **Verdict:** Clean - **Confidence:** 83.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook runs only on non-Windows npm installs and selects a binary matching the platform and architecture., The hook copies that binary over the CLI shim only after it runs successfully with --version; failures leave the shim in place., The CLI shim forwards arguments to the matching bundled native binary., The native binary report contains TeamMesh API and sync host strings, consistent with the package’s stated team-connection CLI purpose. - **Evidence against:** The native binaries are not fully inspectable in the available offline reports, so their runtime behavior cannot be confirmed from source. ## Affected versions and remediation This report applies to teammesh@0.43.2. - Review the evidence and your use of teammesh@0.43.2 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.

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 = 9713664 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:** 83.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook runs only on non-Windows npm installs and selects a binary matching the platform and architecture. Public source snippet (untrusted): ```json "bin": { "tm": "bin/tm.js" }, "scripts": { "postinstall": "node install.js" }, "files": [ "bin", ``` ### 10. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 83.0% - **Path:** install.js - **Public source:** [View source]() The postinstall hook runs only on non-Windows npm installs and selects a binary matching the platform and architecture. Public source snippet (untrusted): ```javascript if (!(process.env.npm[redacted] ?? "").startsWith("npm/")) process.exit(0); const binary = path.join(__dirname, "native", `${process.platform}-${process.arch}`, "tm"); if (!fs.exist ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 83.0% - **Path:** install.js - **Public source:** [View source]() The hook copies that binary over the CLI shim only after it runs successfully with --version; failures leave the shim in place. Public source snippet (untrusted): ```javascript execFileSync(staged, ["--version"], { stdio: "ignore" }); fs.renameSync(staged, shim); } catch { fs.rmSync(staged, { force: true }); process.exit(0); } // The pools LaunchAgent may still be r ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 83.0% - **Path:** bin/tm.js - **Public source:** [View source]() The CLI shim forwards arguments to the matching bundled native binary. Public source snippet (untrusted): ```javascript #!/usr/bin/env node // Runs this platform's native `tm` binary, shipped under // native/-/, with the same arguments. const { spawnSync } = require("node:child_process"); const fs = require("node:fs"); const os = require("node:os"); co ``` ## 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:** 0.43.2 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-11-03T22:10:49.126Z - **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:** 66,564,886 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
