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 hook replaces the package's own CLI shim with its matching bundled binary after a version check, and the shim forwards user-supplied arguments to that binary. The inspected JavaScript shows no unrelated data collection, external contact, or other attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-11-04T02:10:34.945Z - **Finished:** 2026-11-04T02:12:10.145Z - **Download time:** 22945 ms - **Static scan time:** 165 ms - **AI review time:** 72089 ms - **Total time:** 95200 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 install hook prepares the package's CLI binary, which the command shim invokes. - **Trigger:** npm postinstall, then explicit user invocation of tm. - **Impact:** No harmful behavior was established from the inspected sources. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T02:12:10.145Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook conditionally tests and installs the package's matching bundled binary; the shim forwards command-line arguments to that binary. - **Rationale:** The postinstall hook replaces the package's own CLI shim with its matching bundled binary after a version check, and the shim forwards user-supplied arguments to that binary. The inspected JavaScript shows no unrelated data collection, external contact, or other attack behavior. - **Files touched:** bin/tm.js, bin/tm.js.native ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest defines a postinstall hook that runs install.js and exposes bin/tm.js as the tm command., The hook conditionally stages the matching bundled platform binary, runs it with --version, and replaces the shim only if that succeeds., The hook's additional command is described as checking for a running pools manager and printing an upgrade notice; it stays silent on ordinary installs., The CLI shim selects the bundled binary for the current platform and forwards the user's arguments to it. ## Affected versions and remediation This report applies to teammesh@0.47.0. - Review the evidence and your use of teammesh@0.47.0 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node install.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node install.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Medium: Ships Native Binary - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** native/win32-arm64/tm.exe - **Public source:** [View source]() Package ships native binary artifacts. Public source snippet (untrusted): ```text path = native/win32-arm64/tm.exe kind = native_binary sizeBytes = 9690112 magicHex = [redacted] ``` ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 80.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 9. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 84.0% - **Path:** package.json - **Public source:** [View source]() The manifest defines a postinstall hook that runs install.js and exposes bin/tm.js as the tm command. Public source snippet (untrusted): ```json "bin": { "tm": "bin/tm.js" }, "scripts": { "postinstall": "node install.js" }, "files": [ "bin", "native", "in ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 84.0% - **Path:** install.js - **Public source:** [View source]() The hook conditionally stages the matching bundled platform binary, runs it with --version, and replaces the shim only if that succeeds. 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(binary)) process.exit(0); const ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 84.0% - **Path:** install.js - **Public source:** [View source]() The hook conditionally stages the matching bundled platform binary, runs it with --version, and replaces the shim only if that succeeds. Public source snippet (untrusted): ```javascript try { fs.copyFileSync(binary, staged); fs.chmodSync(staged, 0o755); // Only swap in a binary that actually runs here. execFileSync(staged, ["--version"], { stdio: "ignore" }); fs.renameSync(staged, shim); } catch { fs.rmSync(staged, { force: true }); process.exit(0); } // The pools LaunchAgent may still be running from the package npm just // ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 84.0% - **Path:** install.js - **Public source:** [View source]() The hook's additional command is described as checking for a running pools manager and printing an upgrade notice; it stays silent on ordinary installs. Public source snippet (untrusted): ```javascript // The pools LaunchAgent may still be running from the package npm just // unlinked. Ask the installed native CLI to hand over that manager; ordinary // installs and platforms without the pools manager stay silent. try { const notice = execFileSync(shim, ["__pools-upgrade-notice"], { encoding: "utf8" }); if (notice ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** teammesh - **Ecosystem:** npm - **Version:** 0.47.0 - **License:** SEE LICENSE IN LICENSE - **Version published:** 2026-11-04T02:08:14.340Z - **Package first seen:** 2026-10-16T15:07:14.061Z - **Package last seen:** 2026-11-04T20:01:36.217Z - **Known versions:** 70 - **Latest version:** 0.49.1 - **Appeal under review:** No - **Description:** TeamMesh CLI: connects AI coding agents to your team - **Maintainers:** hassaans - **Runtime engines:** node: \>=18 - **Artifact files:** 10 - **Artifact unpacked size:** 66,393,278 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
