## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 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:** 4.4.6
- **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.

The inspected behavior matches a browser CAPTCHA bundle: no lifecycle hook is declared, and detector prefetch is gated by site-key and start-mode checks. The environment reference and generated runtime import do not establish malicious behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-10-09T16:42:26.728Z

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 identified in the inspected package entrypoint. The bundle exposes CAPTCHA widget behavior and starts a provider detector prefetch when a site key is available.

- **Trigger:** Loading the browser bundle or calling render with a site key; automatic prefetch is skipped in manual start mode.

- **Impact:** No confirmed malicious effect or attack surface was established from the inspected behavior.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T16:43:00.439Z

### AI review details

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

- **Mechanism:** The bundle dynamically imports Prosopo detector modules and passes them the configured environment, IP mode, and site key.

- **Rationale:** The inspected behavior matches a browser CAPTCHA bundle: no lifecycle hook is declared, and detector prefetch is gated by site-key and start-mode checks. The environment reference and generated runtime import do not establish malicious behavior.

### Review decision

- **Verdict:** Clean

- **Confidence:** 88.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json identifies a browser-oriented module entrypoint and contains no install lifecycle hook., dist/index.js imports the package’s declared application modules and local widget utilities; the dependency bridge is ordinary bundler output., src/index.ts gates detector prefetch on a site key and skips it in manual mode., The prefetch passes the site key and IP preference to the Prosopo detector module; no unrelated credential or consumer-file access is shown.

## Affected versions and remediation

## 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@4.4.6/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:** 88.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@prosopo/procaptcha-bundle@4.4.6/package.json>)

package.json identifies a browser-oriented module entrypoint and contains no install lifecycle hook.

Public source snippet (untrusted):

```json
"main": "dist/index.js",
	"type": "module",
	"sideEffects": false,
	"engines": {
		"node": "^24",
		"npm": "^11"
	},
	"exports": {
		".": {
			"types": "./dist/index.d.ts",
			"import": "./dist/index
```

### 9. Low: Suspicious Dependency Evidence
- **Category:** Dependency
- **Confidence:** 88.0%
- **Path:** dist/index.js
- **Public source:** [View source](<https://unpkg.com/@prosopo/procaptcha-bundle@4.4.6/dist/index.js>)

dist/index.js imports the package’s declared application modules and local widget utilities; the dependency bridge is ordinary bundler output.

Public source snippet (untrusted):

```javascript
import "./_virtual/_rolldown/runtime.js";
import { extractParams, getProcaptchaScript } from "./util/config.js";
import { resolveStartMode } from "./util/startMode.js";
import { WidgetFactory } from "./util/widgetFactory.js";
impo
```

### 10. Low: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 88.0%
- **Path:** src/index.ts
- **Public source:** [View source](<https://unpkg.com/@prosopo/procaptcha-bundle@4.4.6/src/index.ts>)

src/index.ts gates detector prefetch on a site key and skips it in manual mode.

Public source snippet (untrusted):

```typescript
fetch = (
	siteKey: string | null,
	flags: { ipv4?: boolean; ipv6?: boolean; startMode?: StartModeEnum },
): void => {
	if (!siteKey) return;
	if (flags.startMode === StartModeEnum.manual) return;
	void Promise.all([
		import("@prosopo/procaptcha-frictionless"),
		import("@prosop
```

### 11. Low: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 88.0%
- **Path:** src/index.ts
- **Public source:** [View source](<https://unpkg.com/@prosopo/procaptcha-bundle@4.4.6/src/index.ts>)

The prefetch passes the site key and IP preference to the Prosopo detector module; no unrelated credential or consumer-file access is shown.

Public source snippet (untrusted):

```typescript
),
	])
		.then(([frictionless, common]) => {
			frictionless.prefetchDetector(
				process.env.PROSOPO_DEFAULT_ENVIRONMENT as EnvironmentTypes,
				common.pickIpMode(flags),
				siteKey,
			);
		})
```

### 12. Low: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 88.0%
- **Path:** src/index.ts
- **Public source:** [View source](<https://unpkg.com/@prosopo/procaptcha-bundle@4.4.6/src/index.ts>)

src/index.ts gates detector prefetch on a site key and skips it in manual mode.

Public source snippet (untrusted):

```typescript
export const render = async (
	element: Element,
	renderOptions: ProcaptchaRenderOptions,
): Promise<string | undefined> => {
	startDetectorPrefetch(renderOptions.siteKey, {
		...renderOptions,
		startMode: resolveStartMode(render
```
