Security audit

LLM助手中枢

Security checks for vulnerabilities and agentic risk

Overview

This looks like a document-analysis skill, but it asks for command execution and file-writing powers that are not explained.

Review this before installing. The skill does not show malware-like behavior, but it requests command execution and file-writing authority for what is described as document analysis. Prefer installing only if the publisher narrows the tool permissions or clearly documents when commands and file changes are allowed, with explicit user confirmation.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Behavioral ASTexec() Call, eval() Call, Dynamic Import
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The display name, summaries, and the full skill content are presented in Chinese, with no indication that users may choose another language or that the skill is intentionally restricted to a Chinese-language or region-specific context. That creates a natural-language policy concern because it imposes a locale/language choice without opt-in.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The description is broadly phrased as applicable to generic development scenarios and reusable workflows, without clear trigger boundaries or narrow activation criteria. Overly broad activation language can cause the agent to invoke this skill in contexts unrelated to long-document analysis, exposing exec/write capabilities more often and making prompt-trigger confusion easier.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The tool list exposes read, exec, and write, but the user-facing markdown does not prominently warn that the skill can execute commands and modify data. This is dangerous because users may reasonably treat it as a passive analysis skill while it actually has side-effecting capabilities, undermining informed consent and increasing the risk of covert file changes or command execution.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill advertises itself as a document reasoning/analysis tool, yet declares both exec and write capabilities without any task-bound justification, guardrails, or constrained execution model. This creates an unnecessary privilege expansion: a user invoking a seemingly analytical skill could cause filesystem changes or command execution far beyond the documented purpose, increasing the blast radius of prompt injection or accidental misuse.
