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 performs a local replacement with the package's bundled CLI, and the JavaScript entry point only launches that binary with the user's arguments. The native binaries are largely unreadable in the supplied analysis, but the available evidence does not establish malicious or otherwise suspicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-04T00:19:44.425Z - **Finished:** 2026-11-04T00:20:41.931Z - **Download time:** 7636 ms - **Static scan time:** 164 ms - **AI review time:** 49706 ms - **Total time:** 57506 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 stages the bundled CLI binary, and the command wrapper runs it with the user's arguments. - **Trigger:** The postinstall hook runs during installation; the native CLI runs when the user invokes tm. - **Impact:** The visible install-time behavior is a local CLI setup. The binary strings include TeamMesh service hosts and a Sentry crash-reporting DSN, but do not establish a harmful data flow. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T00:20:41.931Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies a platform binary over bin/tm.js after checking it with --version. The wrapper launches that binary. The native implementation is mostly unreadable from the supplied analysis, so its full behavior could not be confirmed. - **Rationale:** The install hook performs a local replacement with the package's bundled CLI, and the JavaScript entry point only launches that binary with the user's arguments. The native binaries are largely unreadable in the supplied analysis, but the available evidence does not establish malicious or otherwise suspicious behavior. - **Files touched:** bin/tm.js - **Network endpoints:** api.teammesh.io, sync.teammesh.io, o4512288884326400.ingest.us.sentry.io ### Review decision - **Verdict:** Clean - **Confidence:** 82.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package describes itself as a TeamMesh CLI for connecting AI coding agents to a team., The postinstall script locally replaces the JavaScript shim with a matching bundled native binary; it makes no network request., The CLI wrapper selects and runs the bundled platform binary with the user's arguments., Readable binary strings name TeamMesh API and sync hosts, plus a Sentry crash-reporting DSN; the available view does not establish what data is sent or when. - **Evidence against:** The postinstall hook modifies bin/tm.js and executes the staged binary with --version, so install-time execution is present., Most native binaries could not be meaningfully inspected, and the Windows x64 analysis is explicitly limited. ## Affected versions and remediation This report applies to teammesh@0.45.0. - Review the evidence and your use of teammesh@0.45.0 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. 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 = 9721856 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: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 82.0% - **Path:** package.json - **Public source:** [View source]() The package describes itself as a TeamMesh CLI for connecting AI coding agents to a team. Public source snippet (untrusted): ```json "name": "teammesh", "version": "0.45.0", "description": "TeamMesh CLI: connects AI coding agents to your team", "license": "SEE LICENSE IN LICENSE", "repository": { "type" ``` ### 10. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 82.0% - **Path:** install.js - **Public source:** [View source]() The postinstall script locally replaces the JavaScript shim with a matching bundled native binary; it makes no network request. Public source snippet (untrusted): ```javascript // postinstall: replace the JS shim at bin/tm.js with the native binary, so // running `tm` doesn't start Node first. Agent hooks run `tm` on every event, // so that startup cost matters. // // Best effort: if anything goes wrong the shim stays and still works ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 82.0% - **Path:** bin/tm.js - **Public source:** [View source]() The CLI wrapper selects and runs the bundled platform binary with the user's arguments. 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, ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 82.0% - **Path:** .lpm-inspection-d8lQrQ/5-7f0649137725.txt - **Public source:** [View source]() Readable binary strings name TeamMesh API and sync hosts, plus a Sentry crash-reporting DSN; the available view does not establish what data is sent or when.
