Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package runs a downloader automatically. It retrieves and executes an unverified native binary whose install behavior is not present in this package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-11T04:26:40.749Z - **Finished:** 2026-09-11T04:27:14.286Z - **Download time:** 258 ms - **Static scan time:** 53 ms - **AI review time:** 33225 ms - **Total time:** 33537 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:** Installing the package runs a downloader automatically. It retrieves and executes an unverified native binary whose install behavior is not present in this package. - **Trigger:** npm installation that runs postinstall - **Impact:** The remote binary can perform arbitrary actions with the installing user’s permissions. - **Evidence paths:** package.json, bin.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T04:27:14.286Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** download and execute a remote native installer - **Rationale:** This is a transparent but automatic remote-binary execution chain, creating a concrete supply-chain risk. The snapshot does not establish a malicious payload or exfiltration, so a warning is more proportionate than a block. - **Files touched:** ~/.local/bin/nur, %USERPROFILE%\\.local\\bin\\nur.exe - **Network endpoints:** https://github.com/nuroctane/nur-cli/releases/latest/download, https://github.com/nuroctane/nur-cli/releases/download/v0.31.0 ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** An automatic postinstall hook invokes the downloader., The hook fetches an unpinned latest native release asset from GitHub, following redirects., It writes that opaque binary to the user’s local bin directory and executes its install command., The executed binary is outside this package snapshot, so its installation behavior cannot be verified here. - **Evidence against:** The downloader targets the package’s named GitHub repository and has no credential collection or exfiltration code., The JavaScript itself contains no obfuscation, eval, or hidden persistence logic. ## Affected versions and remediation This report applies to nur-cli@0.35.4. - Review the evidence and your use of nur-cli@0.35.4 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: 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 bin.js --ensure || exit 0 ``` ### 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: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() An automatic postinstall hook invokes the downloader. Public source snippet (untrusted): ```json "scripts": { "postinstall": "node bin.js --ensure || exit 0" } ``` ### 9. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** bin.js - **Public source:** [View source]() The hook fetches an unpinned latest native release asset from GitHub, following redirects. Public source snippet (untrusted): ```javascript const versions = ["latest/download", `download/v${FALLBACK_VERSION}`]; const urls = []; for (const v of versions) { for (const name of asset.names) { urls.push(`https://github.com/${REPO}/releases/${v}/${name}`); } } ``` ### 10. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** bin.js - **Public source:** [View source]() It writes that opaque binary to the user’s local bin directory and executes its install command. Public source snippet (untrusted): ```javascript const dest = installedBinaryPath(); fs.writeFileSync(dest, buf); if (asset.execBit) fs.chmodSync(dest, 0o755); process.stdout.write(`nur-cli: installed ${dest}\n`); return dest; } function runNurInstall(bin) { // Full one-stop install: PATH wiring, prereqs, ecosystem packs, browser. // The binary owns all of it - same as double-clicking a release EXE. const r = spawnSync(bin, ["install"], { stdio: "inherit" }); ``` ### 11. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** bin.js - **Public source:** [View source]() The executed binary is outside this package snapshot, so its installation behavior cannot be verified here. Public source snippet (untrusted): ```javascript if (args.includes("--ensure")) { if (fs.existsSync(installedBinaryPath())) { process.stdout.write("nur-cli: native binary already installed\n"); return; } const bin = await downloadAndInstall(); runNurInstall(bin); return; } ``` ## 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:** nur-cli - **Ecosystem:** npm - **Version:** 0.35.4 - **License:** MIT - **Version published:** 2026-09-11T02:26:45.266Z - **Package first seen:** 2026-08-22T02:41:30.424Z - **Package last seen:** 2026-10-07T20:13:47.424Z - **Known versions:** 25 - **Latest version:** 0.43.3 - **Appeal under review:** No - **Description:** NurCLI - fully loaded multi-provider coding agent (TUI, vision, tools, sandbox, skills).
