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 hook and launcher have a plausible CLI setup and dispatch role, with no visible data collection. The native binaries contain network and crash-reporting indicators, but the core implementation is not readable enough to establish its behavior, so manual review is needed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 85.0% - **Started:** 2026-10-31T04:50:31.380Z - **Finished:** 2026-10-31T04:51:04.791Z - **Download time:** 1029 ms - **Static scan time:** 168 ms - **AI review time:** 32213 ms - **Total time:** 33411 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 native CLI is the package’s main implementation, and its behavior cannot be established from the available binary analysis. - **Trigger:** The postinstall hook may replace the launcher with the platform binary; normal CLI use then invokes that binary. - **Impact:** Any runtime network or telemetry behavior remains unverified, so this review cannot determine whether it is expected or risky. - **Evidence paths:** native/linux-arm64/tm, native/darwin-x64/tm, native/darwin-arm64/tm, native/linux-x64/tm, native/win32-arm64/tm.exe, native/win32-x64/tm.exe - **Review source:** ai\_review - **Reviewed:** 2026-10-31T04:51:04.791Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The available analysis exposes endpoint and crash-reporting strings but not the native code paths, transmitted data, or triggers. - **Rationale:** The JavaScript install hook and launcher have a plausible CLI setup and dispatch role, with no visible data collection. The native binaries contain network and crash-reporting indicators, but the core implementation is not readable enough to establish its behavior, so manual review is needed. - **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:** Manual Review - **Confidence:** 85.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The postinstall hook conditionally copies a platform binary over the JavaScript launcher and checks it with --version., The launcher passes its arguments directly to the native binary., The readable binary view contains TeamMesh API and sync endpoints, plus a Sentry crash-reporting endpoint and TM\_CRASH\_REPORTS flag. - **Evidence against:** The visible install hook does not itself send data; it selects, copies, and tests a local binary., The native binaries are the CLI’s main implementation, but most have no supported behavioral analysis; the readable strings do not establish what data is sent or when. ## Affected versions and remediation This report applies to teammesh@0.34.6. - Review the evidence and your use of teammesh@0.34.6 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.
