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 inspected JavaScript establishes that the CLI delegates execution to bundled native binaries. Offline analysis could not resolve behavior for several platform binaries and left the Windows x64 call graph incomplete, so a clean or malicious verdict is not supported by the available source evidence. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-22T17:15:31.503Z - **Finished:** 2026-10-22T17:16:19.600Z - **Download time:** 3069 ms - **Static scan time:** 163 ms - **AI review time:** 44865 ms - **Total time:** 48097 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 confirmed in the inspected JavaScript. The package installs and runs bundled native executables whose behavior remains unresolved. - **Trigger:** An npm installation may replace the CLI shim with a native binary; running the CLI then launches that binary. - **Impact:** The native executable's behavior could not be sufficiently assessed, so its effects remain unknown. - **Evidence paths:** package.json, install.js, bin/tm.js, .lpm-inspection-jPApLN/0-37cffaa6f9c4.txt, .lpm-inspection-jPApLN/1-022949cbce35.txt, .lpm-inspection-jPApLN/2-0963b0a76a50.txt, .lpm-inspection-jPApLN/3-5240f53d9b09.txt, .lpm-inspection-jPApLN/4-42b8b3050d47.txt, .lpm-inspection-jPApLN/5-6e971bdbeab2.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-22T17:16:19.600Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall probes a staged platform binary and swaps it into the CLI path. The shim forwards CLI arguments to the native executable. - **Rationale:** The inspected JavaScript establishes that the CLI delegates execution to bundled native binaries. Offline analysis could not resolve behavior for several platform binaries and left the Windows x64 call graph incomplete, so a clean or malicious verdict is not supported by the available source evidence. - **Files touched:** package.json, install.js, bin/tm.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 91.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json runs install.js from an npm postinstall hook., install.js probes the staged native binary, then replaces the CLI shim with it., bin/tm.js launches the platform-specific native binary with the CLI arguments., The Linux and macOS native analyses report that executable behavior remains unresolved., The Windows ARM64 binary is unsupported by the analysis, and the Windows x64 call graph is incomplete. ## Affected versions and remediation This report applies to teammesh@0.24.2. - Review the evidence and your use of teammesh@0.24.2 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.
