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 JavaScript install and launch paths are visible, but execution is handed to bundled native binaries that the available analyses leave unresolved or only partially inspected. The evidence does not establish a concrete attack, so the native runtime requires manual review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-25T00:40:45.674Z - **Finished:** 2026-10-25T00:41:36.642Z - **Download time:** 15410 ms - **Static scan time:** 159 ms - **AI review time:** 35398 ms - **Total time:** 50968 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 package installs and launches bundled native CLI binaries. Their behavior remains unresolved because the available analyses do not fully inspect them; no concrete attack was identified in the inspected JavaScript. - **Trigger:** Package installation runs the postinstall hook; later CLI use launches the matching native binary. - **Impact:** The native executable can perform the CLI's runtime actions, but those actions could not be assessed from the available analysis. - **Evidence paths:** .lpm-inspection-mMzth3/0-5add2d021fe9.txt, .lpm-inspection-mMzth3/1-343c74764d5a.txt, .lpm-inspection-mMzth3/2-c3c6d79774cc.txt, .lpm-inspection-mMzth3/3-db361e40a5f1.txt, .lpm-inspection-mMzth3/4-8b3bd90c4e12.txt, .lpm-inspection-mMzth3/5-7581bee3b066.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-25T00:41:36.642Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook stages a native binary as the CLI shim, and the shim forwards command-line arguments to it. - **Rationale:** The JavaScript install and launch paths are visible, but execution is handed to bundled native binaries that the available analyses leave unresolved or only partially inspected. The evidence does not establish a concrete attack, so the native runtime requires manual review. - **Files touched:** 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:** 91.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The postinstall hook runs install.js., The hook stages a bundled native binary and replaces the CLI shim after checking that the binary runs., The CLI shim forwards its arguments to the native executable., The native analyses leave platform binaries unresolved or only partially inspected, so their runtime behavior cannot be cleared from source. - **Evidence against:** The install hook exits on Windows and when the npm user agent check does not pass; it also skips platforms without a matching binary., The inspected JavaScript contains no confirmed credential transfer or unrelated network request. ## Affected versions and remediation This report applies to teammesh@0.29.1. - Review the evidence and your use of teammesh@0.29.1 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 = 9308160 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:** 91.0% - **Path:** package.json - **Public source:** [View source]() The postinstall hook runs install.js. Public source snippet (untrusted): ```json "postinstall": "node install.js" }, ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** install.js - **Public source:** [View source]() The hook stages a bundled native binary and replaces the CLI shim after checking that the binary runs. Public source snippet (untrusted): ```javascript fs.copyFileSync(binary, staged); fs.chmodSync(staged, 0o755); // Only swap in a binary that actually runs here. execFileSync(staged, ["--version"], { stdio: "ignore" }); fs.renameSyn ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** bin/tm.js - **Public source:** [View source]() The CLI shim forwards its arguments to the native executable. Public source snippet (untrusted): ```javascript const result = spawnSync(binary, process.argv.slice(2), { stdio: "inherit" }); if (result.error) { console.error(`tm: ${result.error.message}`); process.exi ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** .lpm-inspection-mMzth3/0-5add2d021fe9.txt - **Public source:** [View source]() The native analyses leave platform binaries unresolved or only partially inspected, so their runtime behavior cannot be cleared from source. Public source snippet (untrusted): ```text Inspection failed without executing artifact. ``` ## 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:** 0.29.1 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-10-25T00:38:42.162Z - **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:** 63,468,883 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
