Moltbook Curator

Security checks for vulnerabilities and agentic risk

Overview

This is a small markdown API guide for submitting and voting on Moltbook curation posts, with its external network actions plainly disclosed and aligned with that purpose.

Installing this skill means an agent may use the documented external Moltbook Curator API when you ask it to suggest or vote on posts. Review the URL and description before posting because submitted suggestions are sent to a third-party service and may be visible in the curation workflow.

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

Finding

The skill instructs the agent to transmit user- or agent-supplied data to an external third-party service via a POST request. Even though the payload appears limited to a Moltbook URL, description, and agent name, this still creates a data exfiltration channel and causes the agent to take network actions outside the local trust boundary without any visible authentication, allowlisting rationale, or user-consent safeguards.
