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 inspected installer and launcher show a version-checked native-binary handoff, but the shipped executables are the primary runtime and several could not be analyzed. This unresolved behavior warrants a warning; the available source does not establish a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 80.0% - **Started:** 2026-10-23T17:43:45.120Z - **Finished:** 2026-10-23T17:44:30.227Z - **Download time:** 4109 ms - **Static scan time:** 165 ms - **AI review time:** 40832 ms - **Total time:** 45107 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 concrete attack was identified in the inspected JavaScript. The postinstall hook can switch the CLI to shipped native executables whose behavior remains unresolved. - **Trigger:** Package installation through npm on a supported non-Windows platform can replace the launcher; invoking the CLI then runs the native executable. - **Impact:** The native program's behavior cannot be established from the available offline analyses, so potential effects remain unknown. - **Evidence paths:** package.json, install.js, bin/tm.js, .lpm-inspection-Sr0DEm/0-08c7ee7c6d79.txt, .lpm-inspection-Sr0DEm/1-2a68fa73928c.txt, .lpm-inspection-Sr0DEm/2-b579cd997bd4.txt, .lpm-inspection-Sr0DEm/3-d3b939569464.txt, .lpm-inspection-Sr0DEm/4-ff02886c0e1d.txt, .lpm-inspection-Sr0DEm/5-52eb282ba22f.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-23T17:44:30.227Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook copies a platform executable over the JavaScript launcher after a version check, and the launcher passes CLI arguments to that executable. - **Rationale:** The inspected installer and launcher show a version-checked native-binary handoff, but the shipped executables are the primary runtime and several could not be analyzed. This unresolved behavior warrants a warning; the available source does not establish a concrete attack. - **Files touched:** package.json, install.js, bin/tm.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 80.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs install.js as a postinstall hook., The hook can replace the JavaScript launcher with a native executable, and the launcher runs that executable when invoked., The shipped native executables could not be fully inspected, leaving their behavior unresolved. - **Evidence against:** The install hook checks the staged executable with a version command before replacing the launcher and removes the staged copy if that check fails. ## Affected versions and remediation This report applies to teammesh@0.27.0. - Review the evidence and your use of teammesh@0.27.0 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.
