Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed data-analysis helper with no evidence of hidden access, persistence, exfiltration, or destructive behavior.

Installers should know this appears intended for Chinese-language data-analysis workflows. Review any separately installed aggregation skills it may ask the agent to use, especially finance or search-related skills, because those would carry their own data-access and reliability considerations.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding

This markdown file contains user-facing instructions and descriptions exclusively in Chinese, and nowhere indicates that the user may choose another language or that the skill is limited to a Chinese-speaking context. Per the policy, forcing a specific language without user opt-in is a natural-language policy violation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

This code contains natural-language descriptions such as the module title and function documentation entirely in Chinese, and the command-line interface provides usage/help text oriented to that language context. Under the policy, forcing a specific language without offering a user choice or documenting a justified locale constraint is a policy violation.
