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 install and launcher path is understandable, but it activates shipped native code that the available analyses do not adequately resolve. Because that code is central to normal CLI operation, manual review is needed to determine its behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-18T11:27:23.717Z - **Finished:** 2026-10-18T11:27:53.282Z - **Download time:** 2051 ms - **Static scan time:** 143 ms - **AI review time:** 27371 ms - **Total time:** 29565 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 behavior was confirmed in the inspected JavaScript. The CLI delegates to shipped native binaries whose behavior could not be resolved from the available offline analyses. - **Trigger:** Installing with npm may stage a platform binary; invoking the CLI runs the selected platform binary. - **Impact:** The native executable's behavior and effects remain unknown, so the package's runtime impact cannot be determined from the inspected evidence. - **Evidence paths:** .lpm-inspection-BxewVk/5-020f725d3505.txt, .lpm-inspection-BxewVk/3-9432ef83c3bb.txt, .lpm-inspection-BxewVk/0-3baa149ecc35.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T11:27:53.282Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer may replace the JavaScript shim with a native executable, and the shim launches that executable with the supplied arguments. - **Rationale:** The JavaScript install and launcher path is understandable, but it activates shipped native code that the available analyses do not adequately resolve. Because that code is central to normal CLI operation, manual review is needed to determine its behavior. - **Files touched:** package.json, install.js, bin/tm.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 88.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest defines a postinstall hook that runs the installer and exposes the CLI through a JavaScript shim., The installer can replace the shim with a platform binary, and the shim executes that binary with the user's arguments., Offline analysis could not resolve the behavior of the Linux binary; analysis of the Windows x64 binary also leaves targets uninspected. - **Evidence against:** The installer only attempts the replacement for npm on non-Windows systems, checks that the binary runs, and removes the staged copy if replacement fails. ## Affected versions and remediation This report applies to teammesh@0.10.0. - Review the evidence and your use of teammesh@0.10.0 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.

Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 88.0% - **Path:** package.json - **Public source:** [View source]() The manifest defines a postinstall hook that runs the installer and exposes the CLI through a JavaScript shim. Public source snippet (untrusted): ```json "bin": { "tm": "bin/tm.js" }, "scripts": { "postinstall": "node install.js" }, "files": [ "bi ``` ### 10. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 88.0% - **Path:** install.js - **Public source:** [View source]() The manifest defines a postinstall hook that runs the installer and exposes the CLI through a JavaScript shim. Public source snippet (untrusted): ```javascript if (process.platform === "win32") process.exit(0); if (!(process.env.npm[redacted] ?? "").startsWith("npm/")) process.exit(0); const binary = path.join(__dirname, "native", `${process.platform}-${process.arch}`, "tm"); if (!fs.existsSync(bin ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 88.0% - **Path:** bin/tm.js - **Public source:** [View source]() The installer can replace the shim with a platform binary, and the shim executes that binary with the user's arguments.
