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 install hook appears limited to replacing this package’s own CLI shim with its matching native executable. The executable is the main runtime, and material behavior remains unresolved in the available artifact analyses, so manual review is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-20T01:23:46.812Z - **Finished:** 2026-10-20T01:24:28.526Z - **Download time:** 2296 ms - **Static scan time:** 158 ms - **AI review time:** 39259 ms - **Total time:** 41714 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 postinstall hook can replace the package’s CLI shim with a bundled native executable. The hook is narrowly scoped, but the executable is the main runtime and its behavior remains unresolved. - **Trigger:** Installing with npm on a non-Windows platform when a matching bundled executable exists. - **Impact:** The native program runs when the CLI is used; inspection did not establish whether it contains harmful behavior. - **Evidence paths:** install.js, native/linux-arm64/tm, native/win32-x64/tm.exe, .lpm-inspection-hB48Te/1-812ab90e7fdb.txt, .lpm-inspection-hB48Te/3-d6ea3ade6cec.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-20T01:24:28.526Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies the executable, checks it with --version, and renames it over bin/tm.js. - **Rationale:** The install hook appears limited to replacing this package’s own CLI shim with its matching native executable. The executable is the main runtime, and material behavior remains unresolved in the available artifact analyses, so manual review is warranted. - **Files touched:** package.json, install.js, bin/tm.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 88.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json runs install.js as a postinstall hook., install.js restricts the replacement to npm on non-Windows platforms and selects a matching bundled executable., The hook checks that the executable runs, then replaces this package’s own bin/tm.js shim., The Linux ARM64 artifact analysis says its behavior remains unresolved., The Windows x64 analysis leaves native call targets uninspected. ## Affected versions and remediation This report applies to teammesh@0.20.1. - Review the evidence and your use of teammesh@0.20.1 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.

Public source snippet (untrusted): ```text path = native/win32-arm64/tm.exe kind = native_binary sizeBytes = 8027136 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:** 88.0% - **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:** 88.0% - **Path:** install.js - **Public source:** [View source]() install.js restricts the replacement to npm on non-Windows platforms and selects a matching bundled executable. 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" ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 88.0% - **Path:** install.js - **Public source:** [View source]() The hook checks that the executable runs, then replaces this package’s own bin/tm.js shim. 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, shim); } cat ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 88.0% - **Path:** .lpm-inspection-hB48Te/1-812ab90e7fdb.txt - **Public source:** [View source]() The Linux ARM64 artifact analysis says its behavior remains unresolved. Public source snippet (untrusted): ```text limitations=["No supported structural or executable analysis; behavior remains unresolved"] bytes=8421952 magic=[redacted] ``` ## 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:** 0.20.1 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-10-20T01:21:23.642Z - **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:** 52,964,267 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
