## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 11 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 4.4.1
- **Selected version is latest:** No
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Source inspection found a browser CAPTCHA bundle with no lifecycle scripts or malicious primitives. Environment settings and dynamic imports are limited to configuring and loading its declared CAPTCHA dependencies.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 94.0%
- **Started:** 2026-09-07T20:07:59.063Z

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 confirmed malicious attack surface. This is a browser CAPTCHA widget that initializes UI and delegates CAPTCHA handling to declared dependencies.

- **Trigger:** A web page imports or loads the bundle and renders a CAPTCHA widget.

- **Impact:** No package-originated credential theft, persistence, destructive action, install-time mutation, or direct exfiltration was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-07T20:08:51.595Z

### AI review details

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

- **Mechanism:** Widget initialization and CAPTCHA-provider prefetch.

- **Rationale:** Source inspection found a browser CAPTCHA bundle with no lifecycle scripts or malicious primitives. Environment settings and dynamic imports are limited to configuring and loading its declared CAPTCHA dependencies.

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest exposes a browser bundle and contains no install lifecycle hook., The built entry imports local modules and declared Prosopo CAPTCHA dependencies., Source config reads named CAPTCHA settings and passes them into a validated widget configuration., The widget mounts the declared CAPTCHA component; no direct credential harvesting, filesystem access, shell execution, or network primitive was found.

- **Evidence against:** Importing the browser entry performs widget initialization and may prefetch CAPTCHA detection after a caller supplies a site key., Environment-variable references configure the CAPTCHA service; they do not enumerate or exfiltrate the consumer environment., The scanner's runtime dependency bridge is consistent with declared dependencies and the bundle's widget role.

## Public findings

### 1. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

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

Package source references environment variables.

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

Package source references filesystem APIs.

### 4. High: Copied Package Dependency Bridge
- **Category:** Source
- **Confidence:** 83.0%
- **Path:** dist/index.js
- **Public source:** [View source](<https://unpkg.com/@prosopo/procaptcha-bundle@4.4.1/dist/index.js>)

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

Public source snippet (untrusted):

```javascript
package = @prosopo/procaptcha-bundle; repositoryIdentity = captcha; dependency = @prosopo/procaptcha-common
L5: import { WidgetThemeResolver } from "./util/widgetThemeResolver.js";
L6: import { getWindowCallback } from "@prosopo/procaptcha-common";
L7: import { PROCAPTCHA_START_EVENT, StartModeEnum } from "@prosopo/types";
```

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

Package source contains high-entropy string patterns.

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

Package source contains URL literals.

### 7. 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.

### 8. Low: Suspicious Lifecycle Evidence
- **Category:** Manifest
- **Confidence:** 94.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@prosopo/procaptcha-bundle@4.4.1/package.json>)

- **Path:** src/util/configCreator.ts
- **Public source:** [View source](<https://unpkg.com/@prosopo/procaptcha-bundle@4.4.1/src/util/configCreator.ts>)

Source config reads named CAPTCHA settings and passes them into a validated widget configuration.

Public source snippet (untrusted):

```typescript
const siteKey = options.siteKey || process.env.PROSOPO_SITE_KEY || "";

	return ProcaptchaConfigSchema.parse({
		defaultEnvironment: process.env.PROSOPO_DEFAULT_ENVIRONMENT
			? EnvironmentTypesSchema.parse(process.env.PROSOPO_DEFAULT_ENVIRONMENT)
			: EnvironmentTypesSchema.enum.development,
		userAccountAddress: userAccountAddress || "",
		account: {
			address: siteKey,
		},
		serverUrl: process.env.PROSOPO_SERVER_URL || "",
		mongoAtlasUri: process.env.PROSOPO_MONGO_EVENTS_URI || "",

Public source snippet (untrusted):

```typescript
return (
		<ProcaptchaFrictionless
			key={componentKey}
			config={config}
			callbacks={getDefaultEvents(callbacks)}
			restart={restart}
			i18n={i18n}
			container={container}
		/>
