Security audit

Filesystem 1.0.0

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward filesystem command reference with disclosed local file operations and no hidden code, persistence, or exfiltration behavior.

Install only if you want a Chinese-language filesystem command reference. Before using its copy, move, delete, or replace examples, confirm the target directory and preview affected files, especially outside a project workspace.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill advertises broad filesystem capabilities including search, copy, move, and delete operations without defining boundaries such as allowed directories, protected paths, or approval requirements for destructive actions. In an agent setting, this can cause the skill to be invoked for high-risk operations on arbitrary parts of the host filesystem, increasing the chance of unintended data exposure or destruction.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The documentation switches into Chinese and continues presenting the operational guidance in that language, but there is no user opt-in or explanation that the skill is intended only for Chinese-speaking users. This can violate language or locale policy because it imposes a specific language experience by default.

Sudo/Root Execution

Category
Privilege Escalation
Confidence
70% confidence
Finding

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.
