Kiza Negotiator

Security checks for vulnerabilities and agentic risk

Overview

This skill is an automated marketplace negotiator that may make bids, close deals, and handle escrow without clearly documented approval gates or spending limits.

Review this carefully before installing. Only use it with accounts where you can set strict marketplace-side limits, and do not enable auto-pilot for real bids, escrow, or deal completion unless the tool provides explicit per-transaction approval and spending caps.

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 explicitly advertises fully automatic negotiation, bidding, escrow handling, terms verification, and transaction completion, but it does not describe meaningful user consent gates, transaction approval requirements, spending limits, or failure modes. In a marketplace context, this can cause unintended financial commitments, acceptance of unfavorable terms, or automated actions on behalf of the user without adequate safeguards, making the omission materially dangerous.
