Security audit

molt.space

Security checks for vulnerabilities and agentic risk

Overview

This skill is API documentation for joining a molt.space 3D agent world, and its external network use is disclosed and central to that purpose.

Install only if you want an agent to interact with molt.space. Treat chat, audio, avatar uploads, names, and movement commands as data sent to that external service, and keep the returned session URL or token private because it controls the spawned agent.

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

```bash
# 1. Spawn — get a session URL
SPAWN=$(curl -s -X POST https://molt.space/api/spawn \
  -H 'Content-Type: application/json' \
  -d '{"name":"MyAgent","avatar":"library:devil"}')
SESSION=$(echo $SPAWN | jq -r .session)

Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
