The remote manifest is host-restricted but not cryptographically pinned by the package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-21T02:12:21.057Z - **Finished:** 2026-08-21T02:13:35.743Z - **Download time:** 759 ms - **Static scan time:** 1667 ms - **AI review time:** 72258 ms - **Total time:** 74686 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm install, the package obtains a remote runtime manifest, downloads its Python archive, extracts it under the user home, and runs its Python executable for a smoke test. The remote manifest is host-restricted but not cryptographically pinned by the package. - **Trigger:** npm postinstall (unless LEMONCLAW\_SKIP\_RUNTIME\_INSTALL=1) - **Impact:** A compromise of the allowed runtime host could cause unreviewed code execution during package installation. - **Evidence paths:** package.json, dist/postinstall.cjs, runtime-manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-08-21T02:13:35.743Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote manifest-controlled runtime download, extraction, and execution - **Rationale:** The package creates an unconsented install-time remote payload execution path, warranting a warning. Source inspection does not establish malicious intent or behavior beyond that staged runtime delivery mechanism. - **Files touched:** dist/postinstall.cjs, runtime-manifest.json, ~/.lemonclaw-cli/downloads, ~/.lemonclaw-cli/runtimes, ~/.lemonclaw-cli/current.json - **Network endpoints:** https://download.ningmengyun.com/Skills/lemonclaw/runtime-manifest.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** npm postinstall runs the bundled installer., Postinstall automatically bootstraps a remote runtime unless an opt-out variable is set., Remote manifest supplies the archive URL and its accepted SHA-256; it is restricted by host, not a signed pinned manifest., The downloaded archive is extracted and its Python executable is run during installation. - **Evidence against:** Downloads are HTTPS-only and limited to download.ningmengyun.com., Archive size and SHA-256 are checked before extraction., Archive extraction rejects paths outside the expected runtime root. ## 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 dist/postinstall.cjs ``` ### 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 dist/postinstall.cjs ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 5. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 6. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 7. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 8. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 9. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 70.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 10. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 11. Medium: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 93.0% - **Path:** dist/postinstall.cjs - **Public source:** [View source]() Postinstall automatically bootstraps a remote runtime unless an opt-out variable is set. Public source snippet (untrusted): ```javascript async function runPostinstall(options = {}) { const env = options.env || process.env; const stdout = options.stdout || process.stdout; const install = options.bootstrapRuntime || bootstrapRuntime; const timeoutMs = Number(options.timeoutMs || POSTINSTALL_TIMEOUT_MS); const clearTimer = options.clearTimer || clearTimeout; enterSafeWorkingDirectory(options.workingDirectory || os.tmpdir()); if (env.LEMONCLAW_SKIP_RUNTIME_INSTALL === "1") { writeLine(stdout, "LemonClaw runtime installation skipped by build environment."); return { sk ``` ### 12. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 93.0% - **Path:** dist/postinstall.cjs - **Public source:** [View source]() Remote manifest supplies the archive URL and its accepted SHA-256; it is restricted by host, not a signed pinned manifest. Public source snippet (untrusted): ```javascript async function fetchRemoteManifest(options = {}) { const env = options.env || process.env; const trustedHosts = options.trustedHosts || TRUSTED_RUNTIME_HOSTS; const url = options.url || String(env.LEMONCLAW_RUNTIME_MANIFEST_URL || "").trim() || DEFAULT_REMOTE_MANIFEST_URL; const timeoutMs = Number(options.timeoutMs || DEFAULT_MANIFEST_TIMEOUT_MS); const deadline = Math.min(options.deadline ??
