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 and launcher behavior is consistent with installing and running the bundled TeamMesh CLI, with no evidence of unrelated data collection or other attack behavior. A Sentry endpoint and \`TM\_CRASH\_REPORTS\` marker appear in the available Windows binary strings, but those strings do not establish automatic reporting or its contents. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-03T01:03:19.349Z - **Finished:** 2026-11-03T01:04:19.618Z - **Download time:** 6070 ms - **Static scan time:** 169 ms - **AI review time:** 54029 ms - **Total time:** 60269 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 and launches its bundled TeamMesh CLI. - **Trigger:** The postinstall hook runs during npm installation; the native CLI runs when the user invokes \`tm\`. - **Impact:** The inspected behavior supports installing and using the TeamMesh CLI. The native binary strings identify TeamMesh API and sync endpoints; Sentry reporting behavior could not be determined from the available analysis. - **Review source:** ai\_review - **Reviewed:** 2026-11-03T01:04:19.618Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook stages a bundled platform binary, verifies it with \`--version\`, and swaps it into the shim path. The shim forwards arguments to that local binary. - **Rationale:** The postinstall and launcher behavior is consistent with installing and running the bundled TeamMesh CLI, with no evidence of unrelated data collection or other attack behavior. A Sentry endpoint and \`TM\_CRASH\_REPORTS\` marker appear in the available Windows binary strings, but those strings do not establish automatic reporting or its contents. - **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:** Clean - **Confidence:** 82.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest describes TeamMesh as a CLI that connects AI coding agents to the TeamMesh service and declares \`bin/tm.js\` as its command., The postinstall hook uses a bundled platform binary, checks that it runs with \`--version\`, then replaces the JavaScript shim; it does not download or transmit data., The shim launches the matching local native binary with the user's command-line arguments., The available native analysis shows TeamMesh API and sync hosts, consistent with the package's stated service purpose. - **Evidence against:** The package runs a postinstall hook and ships native binaries., The Windows x64 binary analysis contains a Sentry endpoint and \`TM\_CRASH\_REPORTS\`; the available strings do not establish whether reports are sent by default or what they contain., Native analysis is limited or unavailable for several platform binaries. ## Affected versions and remediation This report applies to teammesh@0.36.2. - Review the evidence and your use of teammesh@0.36.2 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.
