小石金融数据平台

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed connector for Xiaoshi financial data and its credential/network behavior is scoped to that purpose.

Before installing, users should be comfortable sharing their email and financial-data queries with Xiaoshi, and should only enable cross-session API key storage through a protected secret store. The skill is for research and data retrieval, not trading or account actions.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Finding

The description on L03 is presented in both Chinese and English, while the rest of the skill content is predominantly Chinese. This can amount to an implicit language/locale constraint because the skill does not state that users may choose their preferred language for interaction or outputs.
