Xerolite

Security checks for vulnerabilities and agentic risk

Overview

The skill openly provides Xerolite/Interactive Brokers trading commands, but it exposes live order execution and trading credentials with too little local safety control.

Review this skill carefully before installing. Use it only with a tightly scoped Xerolite credential, prefer localhost or HTTPS-only trusted endpoints, avoid the --api-key flag, and require a human confirmation or paper-trading workflow before any live order command.

Vulnerability Patterns

Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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

Missing User Warnings

High

Category: Not specified by scanner
Confidence: 97% confidence
Finding: The skill explicitly supports placing live Interactive Brokers orders from natural language or automation, but it does not present a clear warning that these actions are financially irreversible and could cause immediate loss. In this context, the absence of a strong confirmation and risk warning is especially dangerous because accidental, ambiguous, or prompt-influenced requests could trigger real trades.
Content: No source excerpt is available for this finding.

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 94% confidence
Finding: The skill declares environment and network capabilities via metadata and documented API usage, but it does not define an explicit tool scope such as permissions or allowed-tools. That increases the chance an agent can invoke broader capabilities than intended, especially because the skill handles API keys and can perform live trading actions over the network.
Content: No source excerpt is available for this finding.

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 90% confidence
Finding: The API reference documents a live order-placement endpoint that can execute real trades, but it does not warn users that actions are financially consequential and potentially irreversible. In an agent skill context, this increases the chance that an automated system or operator invokes the endpoint without sufficient confirmation, safety checks, or environment separation from production trading.
