Security audit

pyspark-to-excel

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple PySpark table-to-Excel text formatter with no executable code, persistence, network access, or credential use.

Before installing, users should know this skill may be invoked by broad spreadsheet-formatting phrases, so it is best suited for Chinese-language workflows involving pasted PySpark .show() output. It does not appear to run code, access files, contact networks, or persist settings.

A.I.G

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

Confidence
90% confidence
Finding

The trigger list includes broad phrases such as '表格整理', '复制到excel', and '数据格式化', which can match many unrelated user requests and cause this skill to activate outside its intended PySpark .show() conversion scope. Over-broad activation increases the chance that the skill overrides a more appropriate skill or hijacks generic data-handling prompts, leading to unintended instruction application and possible mishandling of user content.

Natural-Language Policy Violations

Low
Category

Confidence
82% confidence
Finding

The manifest description and operating instructions are written entirely in Chinese, which implies a fixed language/locale expectation for use of the skill. There is no indication that users may choose another language or that the Chinese-only presentation is a justified regional constraint.
