Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed A-share market data helper that calls a named external stock-data API and does not include local code, persistence, or hidden behavior.

Before installing, confirm you trust the stock.quicktiny.cn service and understand that your LB_API_KEY will be used in API calls to the configured LB_API_BASE. Treat the returned market interpretation as informational, not trading advice, and note that the skill's limit-up related market fields are broader than its stated exclusion of limit-up board analysis.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Description-Behavior Mismatch

Confidence
96% confidence
Finding

The manifest explicitly excludes 'limit-up board analysis', yet the same skill description and endpoint docs include limit_up_count, limit_down_count, limit_up_broken_count, limit_up_broken_ratio, and analysis guidance around these signals. That is a semantic mismatch between the claimed prohibited use and the actual capability exposed by the skill.

Description-Behavior Mismatch

Low
Category
Not specified by scanner
Confidence
58% confidence
Finding

The file frames the skill as basic A-share market data, but the market overview section adds interpretive guidance such as judging market strength and profitability effect. This does not rise to news intelligence, but it stretches beyond purely neutral data access and weakens the manifest's narrow-scope claim.
