## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. Importing the browser bundle initializes CAPTCHA widgets and prefetches its provider dependency after finding configured CAPTCHA elements.

- **Trigger:** Browser import of dist/index.js on a page containing Procaptcha markup.

- **Impact:** Creates window.procaptcha, dispatches ready/execute events, and renders CAPTCHA UI; no unconsented host mutation or exfiltration established.

- **Evidence paths:** package.json, dist/index.js, dist/util/widgetFactory.js, dist/util/captcha/captchaRenderer.js, dist/util/captcha/components/bundleCaptcha.js, dist/util/configCreator.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T09:04:32.225Z

### AI review details

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

- **Mechanism:** DOM widget rendering and package-aligned CAPTCHA provider prefetch.

- **Rationale:** Static inspection shows a Procaptcha browser widget bundle with expected import-time DOM setup. Environment variables configure the widget; the flagged dynamic imports are package-aligned and no concrete malicious chain was found.

- **Files touched:** package.json, dist/index.js, dist/util/widgetFactory.js, dist/util/captcha/captchaRenderer.js, dist/util/captcha/components/bundleCaptcha.js, dist/util/configCreator.js

### Review decision

- **Verdict:** Clean

- **Confidence:** 95.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has no lifecycle hooks., dist/index.js is browser CAPTCHA widget initialization, not install-time execution., Dynamic imports only load declared @prosopo CAPTCHA dependencies., No filesystem, shell, eval, credential harvesting, or direct network code found.

## 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@4.1.45/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
L4: import { WidgetThemeResolver } from "./util/widgetThemeResolver.js";
L5: import { getWindowCallback } from "@prosopo/procaptcha-common";
L6: import { at } from "@prosopo/util";
```

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

Package source contains URL literals.

### 6. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 40.0%

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