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 postinstall behavior is a platform-specific CLI shim replacement, and the JavaScript entry point simply forwards user arguments to the bundled binary. The available binary strings are consistent with TeamMesh services, though limited analysis cannot determine whether Sentry crash reporting is enabled by default; no concrete attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-04T02:58:29.309Z - **Finished:** 2026-11-04T02:59:35.310Z - **Download time:** 6391 ms - **Static scan time:** 164 ms - **AI review time:** 59446 ms - **Total time:** 66001 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 as a faster executable shim, and the package provides a native team collaboration CLI. - **Trigger:** The postinstall hook runs during installation; ordinary CLI behavior starts when the user runs tm. - **Impact:** The reviewed JavaScript shows no collection or transmission of host, user, project, or credential data. Limited binary analysis shows first-party service endpoints and a Sentry crash-reporting string, but does not establish reporting behavior or whether it is enabled by default. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T02:59:35.310Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies the platform binary, tests it with --version, and replaces bin/tm.js if successful. The shim forwards command arguments to that binary. - **Rationale:** The postinstall behavior is a platform-specific CLI shim replacement, and the JavaScript entry point simply forwards user arguments to the bundled binary. The available binary strings are consistent with TeamMesh services, though limited analysis cannot determine whether Sentry crash reporting is enabled by default; no concrete attack behavior was found. - **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 postinstall hook selects a bundled binary for the current platform and replaces the CLI shim only if that binary runs successfully., The bin entry forwards the user's command arguments to the bundled native CLI., The native binary's readable strings name TeamMesh API and sync endpoints, consistent with the package's team collaboration CLI purpose., The binary strings include a Sentry crash-reporting endpoint and a TM\_CRASH\_REPORTS flag; the available analysis does not establish whether reporting is enabled by default. - **Evidence against:** The manifest declares a postinstall script, so installation does execute package code., The postinstall hook also invokes the installed CLI with a pools-upgrade diagnostic command., The supplied analysis of the Windows binary is limited and does not establish its complete behavior. ## Affected versions and remediation This report applies to teammesh@0.48.0. - Review the evidence and your use of teammesh@0.48.0 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.
