Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward ISO image creation guide whose file, mount, and image-modification commands match its stated purpose.

Install this only if you want an agent to help with ISO image creation and related command examples. Review output paths before running commands, prefer a test directory, and use read-only mounts unless you intentionally need to modify an image.

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
  • Tool MisuseTool Parameter Abuse, Chaining Abuse, Unsafe Defaults
  • 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

Tool Parameter Abuse

High
Category
Tool Misuse
Confidence
85% confidence
Finding

Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill includes numerous commands that create or overwrite ISO files, modify image contents, and mount filesystems, but it does not warn users about side effects such as overwriting existing files, changing local data, or requiring elevated privileges for mount operations. In an agent setting, these examples could be copied or adapted automatically and cause unintended local filesystem changes or destructive writes without explicit user confirmation.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
78% confidence
Finding

The file consistently presents content in Chinese and English together, which may be acceptable, but it does not explicitly offer a user language choice or state whether bilingual output is optional. Under the stated policy, language behavior should either be user-selectable or clearly justified.
