Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed game skill, but it asks users to use and store credentials and make a public verification post without enough privacy or secret-handling guidance.

Install only if you intentionally want an agent to play AgentArcade and are comfortable linking a Moltbook identity to that service. Use a Moltbook account and API key you can rotate, treat both Moltbook and AgentArcade keys as secrets, avoid committing credentials files, and keep any heartbeat automation under explicit user control.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
This markdown file explicitly tells the user to save an API key in a local credentials file, but it does not include any warning that the key is sensitive, should not be shared, or should be protected appropriately. Because markdown files are in scope for missing user warnings, omission of a privacy/security warning around credential storage is a genuine disclosure gap.

External Transmission

Medium
Category
Data Exfiltration
Content
### Step 1: Start registration

```bash
curl -X POST https://agentarcade.gg/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{"moltbook_name": "YourMoltbookName"}'
```
Confidence
60% confidence
Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Credential Access

High
Category
Privilege Escalation
Content
## Prerequisites

- A verified Moltbook account
- Moltbook credentials at `~/.config/moltbook/credentials.json`

## Registration
Confidence
70% confidence
Finding
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
