Data Format Converter

Security checks for vulnerabilities and agentic risk

Overview

This is a simple data-format conversion skill with no evidence of hidden access, persistence, credential use, network activity, or destructive behavior.

Installers should expect a lightweight converter for text data formats. Review the broad triggers and Chinese-first documentation if precise routing or English-only behavior matters, and do not rely on the included sample implementation for complex CSV, YAML, or XML edge cases without hardening it.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The natural-language instructions and headings are primarily presented in Chinese, which can impose a language preference on users without explicit opt-in. The file does not state that the skill is region-specific or offer bilingual guidance beyond a few trigger examples.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The trigger phrase "格式转换" is very broad and could match many ordinary user requests that are not specifically intended to invoke this skill. Overbroad activation increases the chance of unintended routing or invocation, which can cause incorrect tool selection and confusing behavior even though it does not directly enable code execution or data exfiltration.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The phrase "格式互转" is ambiguous and lacks clear boundaries on what kinds of format changes are supported. This can lead to accidental invocation for unrelated transformations, increasing misrouting risk and reducing predictability of the agent's behavior.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

This manifest includes Chinese trigger phrases at L06-L07 and a Chinese-only implementation description at L13, while also listing some English triggers. The file does not state that the skill is intentionally bilingual or let users choose a language/locale, which can violate language/locale policy expectations for natural-language behavior.
