Security checks for vulnerabilities and agentic risk

Overview

This skill is a China-market research helper that uses disclosed public official websites and a small standard-library script without persistence or hidden credential handling.

Install this only if you want a China-official-source market research workflow. Avoid entering secrets, cookies, login-only data, or personal sensitive information; treat submitted search terms as visible to the public official sites being queried.

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
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
Findings (5)

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
93% confidence
Finding

The skill clearly instructs use of networked resources and a browser/API script, but it does not declare any explicit tool scope such as allowed-tools or permissions. That creates an authorization gap where an agent may use broader network capabilities than intended, increasing the chance of uncontrolled outbound access or policy bypass through ambiguous execution context.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The module docstring states this is a "China official free/no-key market research API helper," and the CLI description similarly fixes the skill to China-specific APIs. This imposes a locale-specific scope in natural language without offering a user choice or opt-in, which matches the language/locale policy concern.
