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 readable install code stages a platform-specific CLI, checks that it runs with --version, and then replaces the JavaScript shim. The binary inspection found TeamMesh service endpoints and a Sentry crash-reporting string, but no evidence of malicious collection or actions; opaque native code limits certainty. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-29T18:35:10.603Z - **Finished:** 2026-10-29T18:35:46.968Z - **Download time:** 1027 ms - **Static scan time:** 161 ms - **AI review time:** 35176 ms - **Total time:** 36365 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 package installs a native CLI and validates it during npm postinstall. - **Trigger:** npm postinstall on non-Windows platforms; otherwise, when the user invokes tm. - **Impact:** No harmful behavior was established from the readable source or bounded binary analysis. Several native builds remain opaque, and the Sentry reporting behavior could not be determined. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T18:35:46.968Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies the matching packaged executable, runs it with --version, then replaces bin/tm.js if it succeeds. The JavaScript CLI wrapper forwards arguments to that executable. - **Rationale:** The readable install code stages a platform-specific CLI, checks that it runs with --version, and then replaces the JavaScript shim. The binary inspection found TeamMesh service endpoints and a Sentry crash-reporting string, but no evidence of malicious collection or actions; opaque native code limits certainty. - **Files touched:** bin/tm.js, bin/tm.js.native - **Network endpoints:** api.teammesh.io, sync.teammesh.io, 39a18618b3abf2d4bee26b2b5fefc1d6@o4512288884326400.ingest.us.sentry.io ### Review decision - **Verdict:** Clean - **Confidence:** 76.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook only runs for npm on non-Windows platforms and checks whether a platform binary exists., The installer stages that binary, runs it with --version, and replaces the CLI shim only if the check succeeds., The CLI wrapper runs the matching packaged native binary with the user's arguments., The inspected binary strings name TeamMesh API and sync hosts and a Sentry crash-reporting endpoint; no credential theft or unrelated collector behavior was established. - **Evidence against:** The native executables are the core CLI and several platform builds could not be structurally inspected., The postinstall hook executes the native binary automatically to validate it., The binary strings include a Sentry endpoint and a TM\_CRASH\_REPORTS setting, but the available analysis does not establish when reports are sent or what they contain. ## Affected versions and remediation This report applies to teammesh@0.31.0. - Review the evidence and your use of teammesh@0.31.0 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.
