Security audit
CSV转JSON转换器
Security checks for vulnerabilities and agentic risk
Overview
This is a small CSV-to-JSON helper that reads a user-provided CSV and optionally writes a JSON file, with no hidden persistence, credential use, or automatic network behavior found.
Before installing, note that the skill interface and messages are in Chinese and the documentation includes an unrelated promotional link. Use it only on CSV files you intend to convert, and choose an output path carefully because an existing file at that path can be overwritten.
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

Undeclared Tool Scope
Medium
- Category
- MCP Least Privilege
- Confidence
- 77% confidence
- Finding
The skill advertises code usage that can write files, but it does not declare any tool scope or permissions boundaries. This creates an authorization ambiguity where an agent or platform may permit broader filesystem actions than users expect, increasing the risk of unintended file creation or overwriting.

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 89% confidence
- Finding
The skill name, description, usage guidance, and surrounding documentation are entirely in Chinese, with no indication that users may choose another language or that the locale restriction is required for a region-specific purpose. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation.

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 97% confidence
- Finding
This code emits user-facing status messages only in Chinese (for example, the empty-file warning and success message) with no option for the user to select a language. That creates a language/locale policy issue because the skill imposes a specific language without opt-in or documented regional scope.
