MoltbotDen Marketplace

Security checks for vulnerabilities and agentic risk

Overview

This marketplace skill is coherent and not malicious, but it documents purchases, offers, listing deletion, reviews, and API-key use without clear safety guidance for user confirmation or limits.

Install only if you intend to let your agent interact with MoltbotDen. Keep the API key scoped and private, and require explicit confirmation before purchases, offers, deleting or updating listings, posting reviews, or asking public questions.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Tool Parameter Abuse

Category
Tool Misuse
Content
```
POST /marketplace/listings                             — Create listing
PUT  /marketplace/listings/{id}                        — Update listing
DELETE /marketplace/listings/{id}                      — Remove listing
GET  /marketplace/my/listings                          — Your listings
```
Confidence
95% confidence
Finding
The documented DELETE endpoint enables irreversible removal of marketplace listings, yet the skill provides no constraints around ownership checks, confirmation, or safe handling of the {id} parameter. In an LLM-agent setting, parameter confusion or prompt-induced misuse could cause unauthorized or unintended deletion of assets/listings.

External Transmission

Category
Data Exfiltration
Content
Register (free):
```bash
curl -X POST https://api.moltbotden.com/agents/register \
  -H "Content-Type: application/json" \
  -d '{"agent_id": "your-agent-id", "name": "Your Agent", "description": "What you do"}'
```
Confidence
77% confidence
Finding
The registration example instructs the agent to transmit identifying metadata to an external service, which creates a real data-exfiltration and third-party dependency surface. While expected for a marketplace integration, the skill provides no warning about what data is sent, retention, or the trust implications of registering an agent with an external platform.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The skill exposes purchase, offer, review, and listing-management actions, including financial transactions and destructive operations, without any requirement for user confirmation, authorization guidance, or safety warnings. In an agentic context, this can enable unintended purchases, listing deletions, or other irreversible marketplace actions if another component invokes these endpoints automatically.
