Security audit

Polymarket BTC 5m Arbitrage

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed read-only Polymarket market-data scanner that reports possible price observations but does not trade, handle secrets, or persist anything.

Install only if you are comfortable with a trading-adjacent tool querying public Polymarket market data. Treat its reported edges as observations for manual review, not profit guarantees or trading advice, and do not add private keys, API keys, wallet credentials, billing credentials, or automated order execution to this skill.

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

MCP Least Privilege
Confidence
70% confidence
Finding
Without declared permissions the skill's intent is opaque and cannot be validated.

Natural-Language Policy Violations

Medium
Confidence
90% confidence
Finding
The natural-language content from the title onward is presented only in Chinese, which can amount to forcing a specific language on users. The policy allows locale constraints when users are given a choice or when the constraint is clearly documented and justified, neither of which appears here.
