Security checks for vulnerabilities and agentic risk

Overview

This skill runs a small local demo script that returns fixed example stock lists and does not access live financial data, credentials, persistence, or the network.

Install this only if you want a Chinese-language educational demo that returns fixed sample stocks. It should not be treated as live market data or investment advice, and users should confirm the chosen market before relying on its output in a workflow.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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
Findings (3)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
84% confidence
Finding

The skill description and output examples require Chinese company names and Chinese-formatted output, but there is no indication that users may opt into another language or locale. This can violate language/locale policy when the skill is used in broader contexts beyond a clearly documented region-specific tool.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The skill states it is 'automatically invoked' without defining clear trigger conditions, scope boundaries, or user-consent expectations. In an agent environment, ambiguous auto-invocation can cause the skill to run in unrelated contexts, unexpectedly influence user interactions, or trigger execution of the associated script when the user did not explicitly request stock recommendations.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The module docstring, help text, error messages, and formatted output are all written exclusively in Chinese, which imposes a language choice on users. There is no indication that the tool is intentionally region-specific or that users can opt into another language, matching the policy's language/locale violation criterion.
