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 a postinstall path to bundled native code, and the CLI executes that code for user commands. The available analyses leave native behavior unresolved, so this review cannot determine whether the package is malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-23T04:48:31.977Z - **Finished:** 2026-10-23T04:49:04.510Z - **Download time:** 2547 ms - **Static scan time:** 160 ms - **AI review time:** 29826 ms - **Total time:** 32533 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 confirmed in the inspected JavaScript. The installed CLI runs bundled native code whose behavior could not be resolved from the available artifact analyses. - **Trigger:** Installing through npm on a supported platform can replace the CLI shim; running the CLI then starts the native binary. - **Impact:** The native program’s runtime effects remain unknown, so the package’s behavior cannot be cleared from the inspected evidence. - **Evidence paths:** package.json, install.js, bin/tm.js, .lpm-inspection-mAF6sM/3-999877d8ae20.txt, .lpm-inspection-mAF6sM/5-ea9cf7ef5eba.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-23T04:49:04.510Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall stages and tests a platform binary before replacing the package’s own shim, which forwards later CLI arguments to that binary. - **Rationale:** The inspected JavaScript establishes a postinstall path to bundled native code, and the CLI executes that code for user commands. The available analyses leave native behavior unresolved, so this review cannot determine whether the package is malicious. - **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:** The package runs install.js from its postinstall hook., On supported installs, install.js runs the staged native binary and replaces the package’s CLI shim with it., The CLI shim passes its arguments to the native binary, whose behavior remains unresolved in the available artifact analyses. - **Evidence against:** The inspected JavaScript shows the postinstall changing the package’s own CLI shim; it does not establish a broader filesystem mutation or a confirmed attack. ## Affected versions and remediation This report applies to teammesh@0.26.2. - Review the evidence and your use of teammesh@0.26.2 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.

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 = 9257984 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:** 91.0% - **Path:** package.json - **Public source:** [View source]() The package runs install.js from its postinstall hook. Public source snippet (untrusted): ```json "postinstall": "node install.js" }, "files": [ "bin", "native", "install.js", "LICENSE" ], "engines": { "node": ">=18" } } ``` ### 10. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** install.js - **Public source:** [View source]() On supported installs, install.js runs the staged native binary and replaces the package’s CLI shim with it. Public source snippet (untrusted): ```javascript execFileSync(staged, ["--version"], { stdio: "ignore" }); fs.renameSync(staged, shim); } catch { fs.rmSync(staged, { force: true }); } ``` ### 11. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** bin/tm.js - **Public source:** [View source]() The CLI shim passes its arguments to the native binary, whose behavior remains unresolved in the available artifact analyses.
