Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.49.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The install hook and launcher behave consistently with installing and running the package’s native CLI. However, the limited binary analysis reveals Sentry crash-reporting components without establishing consent, defaults, or collected data, so runtime telemetry remains a user-relevant uncertainty. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 72.0% - **Started:** 2026-11-04T19:59:52.590Z - **Finished:** 2026-11-04T20:01:36.217Z - **Download time:** 36367 ms - **Static scan time:** 258 ms - **AI review time:** 67001 ms - **Total time:** 103627 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 a native CLI; its binary includes crash-reporting components whose default behavior and data collection could not be established. - **Trigger:** The postinstall hook runs during npm installation; the binary otherwise runs when the user invokes tm. - **Impact:** Undisclosed runtime crash telemetry may disclose diagnostic information; the available evidence does not show credential theft or unrelated data collection. - **Evidence paths:** .lpm-inspection-ijG8Qf/5-1018b23127e6.txt, install.js, bin/tm.js - **Review source:** ai\_review - **Reviewed:** 2026-11-04T20:01:36.217Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook checks the native binary with --version and may request an upgrade notice. A limited analysis view shows a Sentry endpoint and TM\_CRASH\_REPORTS setting, but not their runtime behavior. - **Rationale:** The install hook and launcher behave consistently with installing and running the package’s native CLI. However, the limited binary analysis reveals Sentry crash-reporting components without establishing consent, defaults, or collected data, so runtime telemetry remains a user-relevant uncertainty. - **Files touched:** install.js, bin/tm.js, bin/tm.js.native, native/\-\/tm - **Network endpoints:** https://api.teammesh.io, https://sync.teammesh.io, https://39a18618b3abf2d4bee26b2b5fefc1d6@o4512288884326400.ingest.us.sentry.io/4512288887013376 ### Review decision - **Verdict:** Suspicious - **Confidence:** 72.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs install.js as a postinstall hook., On supported npm installs, the hook copies a native binary, marks it executable, runs it with --version, and may invoke an upgrade-notice command., The native analysis view contains a Sentry crash-reporting endpoint and the TM\_CRASH\_REPORTS setting, but does not establish whether reporting is enabled by default or what data it sends., The binary also contains TeamMesh API and sync endpoints consistent with the CLI’s stated purpose., The available native analysis is limited and leaves parts of the binary behavior uninspected. - **Evidence against:** The install hook limits binary replacement to supported platforms and npm, and falls back without failing if the check does not work., The launcher selects the binary matching the current platform and forwards the user’s command-line arguments., The observed API and sync endpoints belong to the package’s own service. ## Affected versions and remediation This report applies to teammesh@0.49.1. - Review the evidence and your use of teammesh@0.49.1 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.
