Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The JavaScript installer and shim show how the native CLI is selected and launched, but static analysis could not resolve most bundled executables and left Windows x64 call targets uninspected. Because those binaries are the package’s runtime, the available source does not establish whether the package is malicious or clean. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-18T02:01:41.770Z - **Finished:** 2026-10-18T02:02:18.494Z - **Download time:** 4898 ms - **Static scan time:** 151 ms - **AI review time:** 31674 ms - **Total time:** 36724 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’s CLI runs bundled native executables. Their behavior remains unresolved from the available static analysis, so a malicious attack surface could not be confirmed or ruled out. - **Trigger:** Installing the package runs its postinstall hook; invoking tm runs the platform-specific binary. - **Impact:** The native CLI’s effects on the system and any network activity remain unknown. - **Evidence paths:** .lpm-inspection-4tQ5YY/0-c111999c4fdc.txt, .lpm-inspection-4tQ5YY/1-cf5af7bc3b34.txt, .lpm-inspection-4tQ5YY/2-5677df09c405.txt, .lpm-inspection-4tQ5YY/3-2fa5fdcc35f3.txt, .lpm-inspection-4tQ5YY/4-9a7847b4343d.txt, .lpm-inspection-4tQ5YY/5-862c1a1b9fe0.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T02:02:18.494Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer may replace bin/tm.js with a native binary, and the shim otherwise launches that binary with the supplied arguments. Available analysis is incomplete or unsupported for these executables. - **Rationale:** The JavaScript installer and shim show how the native CLI is selected and launched, but static analysis could not resolve most bundled executables and left Windows x64 call targets uninspected. Because those binaries are the package’s runtime, the available source does not establish whether the package is malicious or clean. - **Files touched:** package.json, install.js, bin/tm.js, native/win32-arm64/tm.exe, native/linux-arm64/tm, native/darwin-x64/tm, native/win32-x64/tm.exe, native/darwin-arm64/tm, native/linux-x64/tm ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The postinstall hook runs install.js, which can replace the CLI shim with a packaged native binary., The CLI shim forwards its arguments to the platform’s native binary., The native binaries are the CLI’s runtime, but offline analysis could not resolve behavior for most platforms and left uninspected call targets on Windows x64. - **Evidence against:** The installer limits replacement to a matching binary that runs with --version; its comments describe a startup-performance purpose. ## Affected versions and remediation This report applies to teammesh@0.4.0. - Review the evidence and your use of teammesh@0.4.0 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.
