# @kubb/cli@5.15.3 npm security report

## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Telemetry warning (can be blocked)
- **Public report status:** Published
- **Threat category:** Telemetry
- **Selected version:** 5.15.3
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. 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.

The package sends runtime telemetry to its own endpoint by default and includes serialized plugin options, which may expose user-provided configuration. The endpoint and opt-out are visible in source, and no credential theft or unrelated collection was identified; this merits a warning for undisclosed runtime telemetry.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

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:** Undisclosed-by-default runtime telemetry reports command usage and plugin configuration to Kubb.

- **Trigger:** Running a CLI command that calls trackRun, including the Studio command.

- **Impact:** Kubb receives usage information and arbitrary plugin option values, which may include user configuration.

- **Evidence paths:** dist/Telemetry-DuO34wMx.cjs, dist/run-S6Hkmn-h.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-29T20:45:32.449Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The CLI serializes the telemetry payload and POSTs it to the Kubb OpenTelemetry endpoint unless an environment-variable opt-out is set.

- **Rationale:** The package sends runtime telemetry to its own endpoint by default and includes serialized plugin options, which may expose user-provided configuration. The endpoint and opt-out are visible in source, and no credential theft or unrelated collection was identified; this merits a warning for undisclosed runtime telemetry.

- **Network endpoints:** https://otlp.kubb.dev/v1/traces

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** CLI commands send runtime telemetry to https://otlp.kubb.dev by default; users can disable it with DO\_NOT\_TRACK or KUBB\_DISABLE\_TELEMETRY., Telemetry includes serialized plugin options, which can contain user-provided configuration values., Studio command execution starts telemetry reporting without a separate consent step.

- **Evidence against:** The telemetry endpoint belongs to Kubb, and the code documents telemetry as anonymous usage reporting., The payload uses random trace and span IDs and includes command, version, runtime, platform, CI, status, plugin and file-count details., The package has no lifecycle scripts, and telemetry is tied to command runs rather than package import.

## Affected versions and remediation

This report applies to @kubb/cli@5.15.3.

- Review the evidence and your use of @kubb/cli@5.15.3 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: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 2. Medium: Network
- **Category:** Source
- **Confidence:** 75.0%

Package source references network APIs.

### 3. Medium: Environment Vars
- **Category:** Source
- **Confidence:** 75.0%

Package source references environment variables.

### 4. Low: Filesystem
- **Category:** Source
- **Confidence:** 70.0%

Package source references filesystem APIs.

### 5. High: Copied Package Dependency Bridge
- **Category:** Source
- **Confidence:** 83.0%
- **Path:** dist/snapshot-BHFRCLgH.cjs
- **Public source:** [View source](<https://unpkg.com/@kubb/cli@5.15.3/dist/snapshot-BHFRCLgH.cjs>)

Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.

Public source snippet (untrusted):

```javascript
package = @kubb/cli; repositoryIdentity = kubb; dependency = @kubb/core
L12: let node_fs = require("node:fs");
L13: let _kubb_core = require("@kubb/core");
L14: let _kubb_studio = require("@kubb/studio");
```

### 6. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 7. Low: Url Strings
- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 8. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 65.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

### 9. High: Semantic Analysis Limited
- **Category:** Scanner Coverage
- **Confidence:** 100.0%
- **Path:** dist/run-S6Hkmn-h.cjs\#virtual:normalized:round1
- **Public source:** [View source](<https://unpkg.com/@kubb/cli@5.15.3/dist/run-S6Hkmn-h.cjs%23virtual%3Anormalized%3Around1>)

A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.

Public source snippet (untrusted):

```text
stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 1
```

### 10. High: Previous Version Dangerous Delta
- **Category:** Supply Chain
- **Confidence:** 93.0%
- **Path:** dist/run-S6Hkmn-h.cjs
- **Public source:** [View source](<https://unpkg.com/@kubb/cli@5.15.3/dist/run-S6Hkmn-h.cjs>)

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = @kubb/cli@5.15.0
matchedIdentity = npm:QGt1YmIvY2xp:5.15.0
similarity = 0.622
summary = stored previous version shares package body but lacks this dangerous source file
```

### 11. Medium: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 91.0%
- **Path:** dist/Telemetry-DuO34wMx.cjs
- **Public source:** [View source](<https://unpkg.com/@kubb/cli@5.15.3/dist/Telemetry-DuO34wMx.cjs>)

CLI commands send runtime telemetry to https://otlp.kubb.dev by default; users can disable it with DO\_NOT\_TRACK or KUBB\_DISABLE\_TELEMETRY.

Public source snippet (untrusted):

```javascript
* paths, OpenAPI specs, or secrets are sent.
*/
async function sendTelemetry(payload) {
	if (isDisabled()) return;
	try {
		await fetch(`${OTLP_ENDPOINT}/v1/traces`, {
			method: "POST",
			headers: {
				"Content-Type": "application/json",
				"Kubb-Telemetry-Version": "1",
```

### 12. Medium: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 91.0%
- **Path:** dist/Telemetry-DuO34wMx.cjs
- **Public source:** [View source](<https://unpkg.com/@kubb/cli@5.15.3/dist/Telemetry-DuO34wMx.cjs>)

Telemetry includes serialized plugin options, which can contain user-provided configuration values.

Public source snippet (untrusted):

```javascript
value: { arrayValue: { values: plugins.map((p) => ({ kvlistValue: { values: [{
				key: "name",
				value: { stringValue: p.name }
			}, {
				key: "options",
				value: { stringValue: JSON.stringify({
					...p.options,
					usedEnumNames: void 0
				}) }
