## 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:** 4.5.16
- **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 package manifest has no install lifecycle hook, and the inspected entrypoints and required runtime helpers support CAPTCHA widget behavior. The dependency bridge and environment references are consistent with the declared widget and build configuration, with no concrete attack behavior found.

## Latest scan

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 surface was identified in the inspected package entrypoints and required runtime paths. The code initializes CAPTCHA widgets and uses their configuration, language, and form helpers.

- **Trigger:** A consumer imports the package and invokes its widget rendering API.

- **Impact:** No malicious effect was established from the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T17:21:15.369Z

### AI review details

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

- **Mechanism:** The entrypoint loads the widget runtime and declared Prosopo dependencies; inspected helpers configure or mount widgets and handle widget session and form values.

- **Rationale:** The package manifest has no install lifecycle hook, and the inspected entrypoints and required runtime helpers support CAPTCHA widget behavior. The dependency bridge and environment references are consistent with the declared widget and build configuration, with no concrete attack behavior found.

### Review decision

- **Verdict:** Clean

- **Confidence:** 97.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest points to the widget entrypoints and contains build, serve, and test scripts; no install lifecycle hook is present. Its repository path matches this package., The runtime entry initializes and mounts CAPTCHA widgets, while its helpers use caller-provided session, configuration, and timeout values., The inspected declared dependencies expose environment loading, language handling, form cleanup, and CAPTCHA provider functions consistent with the widget runtime; no attack behavior was identified in the required source paths.

## 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%

- **Path:** dist/index.js
- **Public source:** [View source](<https://unpkg.com/@prosopo/procaptcha-bundle@4.5.16/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
L6: import { WidgetThemeResolver } from "./util/widgetThemeResolver.js";
