Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese technical-blog writing skill whose main caveat is that it tells the agent to save the generated post as a Markdown file in the current project.

Before installing, understand that this skill may cause the agent to create a Markdown blog file in the current project; review the filename and destination if preserving existing project files matters.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The natural-language instructions and output conventions are entirely Chinese, and the skill does not indicate that language selection is optional or user-controlled. This can violate language/locale policy when a skill implicitly forces a specific language without opt-in.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill explicitly instructs the agent to save generated content as a .md file in the current project without requiring user confirmation or constraining the path. That creates an unauthorized file-write behavior risk: an agent could modify the workspace unexpectedly, overwrite existing documentation, or persist unreviewed content into a repository.
