## Security analysis

### Published attack-surface review

- **Summary:** At user runtime, the launcher accepts extension metadata and commands from its portal. It can install/run portal-selected npm MCPs and exposes stored secrets to those MCP processes.

- **Trigger:** User runs a \`salesbot\*\` CLI or invokes the MCP install tool through Claude Code.

- **Impact:** A compromised or malicious portal response can execute arbitrary commands and access injected local secrets.

- **Evidence paths:** package.json, dist/index.js, dist/launcher.js, dist/vault.js, launcher.config.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-14T20:25:04.957Z

### AI review details

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

- **Mechanism:** Portal-controlled shell execution and dynamic MCP loading.

- **Rationale:** No concrete malicious payload or unconsented install-time mutation is present, so blocking is not supported by source alone. The unvalidated remote command and secret-injecting dynamic extension loader are a material dangerous capability requiring a warning.

- **Files touched:** dist/index.js, dist/launcher.js, dist/vault.js, launcher.config.json

- **Network endpoints:** https://prompt-injection-tool-portal.vercel.app, https://prompt-injection-tool-portal.vercel.app/api/mcps

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** \`dist/index.js\` POSTs MCP install requests then passes the portal-returned \`command\` directly to \`child\_process.exec\`., \`dist/launcher.js\` fetches portal-defined bundled MCP packages and launches them with \`npx -y\`, injecting locally stored secrets into their environment., \`dist/launcher.js\` checks npm and silently starts detached \`npm install -g @funny-booth/agent-core@latest\` on version mismatch., Obfuscated \`dist/index.js\` and \`dist/launcher.js\` conceal the remote-command and extension-loading behavior.

- **Evidence against:** \`package.json\` has only \`prepublishOnly\`; there is no install-time lifecycle hook., Network calls target the package-configured \`prompt-injection-tool-portal.vercel.app\` portal., Credential storage in \`dist/vault.js\` is local AES-encrypted storage rather than direct harvesting., No hard-coded exfiltration endpoint, destructive filesystem operation, or embedded payload was found.

## Public findings

### 1. Low: Non Install Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 80.0%

Package source references dynamic require/import behavior.

Public source snippet (untrusted):

```javascript
L2: // AUTO-GENERATED by scripts/generate-bins.mjs — do not edit
L3: require("../launcher.js").runLauncher(7).catch((e) => {
L4: process.stderr.write(String((e && e.stack) || e) + "\n");

- **Public source:** [View source](<https://unpkg.com/@funny-booth/agent-core@0.1.7/dist/index.js>)

A single source file combines environment access, network access, and code or shell execution; review context before blocking.

Public source snippet (untrusted):

```javascript
L1: 'use strict';const _0x820cc4=_0x2694;(function(_0x4e8041,_0x49b658){const _0x24602c=_0x2694,_0x3172dd=_0x4e8041();while(!![]){try{const _0x1fd3e3=parseInt(_0x24602c(0x148))/0x1+par...

### 9. High: Obfuscated Payload Loader
- **Category:** Source
- **Confidence:** 86.0%
- **Path:** dist/index.js
- **Public source:** [View source](<https://unpkg.com/@funny-booth/agent-core@0.1.7/dist/index.js>)

Source contains an obfuscator-style string-array loader that reconstructs and executes hidden code.

Public source snippet (untrusted):

```javascript
L1: 'use strict';const _0x820cc4=_0x2694;(function(_0x4e8041,_0x49b658){const _0x24602c=_0x2694,_0x3172dd=_0x4e8041();while(!![]){try{const _0x1fd3e3=parseInt(_0x24602c(0x148))/0x1+par...

- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 12. 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.

### 13. Low: No License
- **Category:** Manifest
- **Confidence:** 80.0%

Package manifest does not declare a clear license.

### 14. Critical: Previous Version Dangerous Delta
- **Category:** Supply Chain
- **Confidence:** 93.0%
- **Path:** dist/index.js
- **Public source:** [View source](<https://unpkg.com/@funny-booth/agent-core@0.1.7/dist/index.js>)

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = @funny-booth/agent-core@0.1.3
matchedIdentity = npm:QGZ1bm55LWJvb3RoL2FnZW50LWNvcmU:0.1.3
similarity = 0.833
summary = stored previous version shares package body but lacks this dangerous source file
