Security checks for vulnerabilities and agentic risk

Overview

This is a localized sales-analysis skill that reads its bundled CSV and creates local chart or PDF outputs, with no evidence of hidden access, network use, persistence, or credential handling.

Install this only if you want a Chinese-language sales-analysis helper for the included CSV-style workflow. Expect it to create PNG charts in /tmp and PDF reports in its reports folder; review generated reports before sharing them.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The trigger conditions are broad enough to activate on generic requests about data, charts, or reports, which can cause the agent to invoke this skill in contexts the user did not intend. Overbroad routing can expose internal data-analysis capabilities unnecessarily, produce misleading outputs, or cause unintended file generation/export actions.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

This code file contains natural-language strings and documentation that force Chinese-language interaction, including the module docstring and later user-facing messages. The policy requires flagging language or locale constraints when the skill does not provide opt-in or a documented justification for restricting output to a specific language.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The manifest description and operational instructions are entirely in Chinese, which effectively forces a specific language for understanding and use. There is no indication that the skill supports language selection or that the Chinese-only scope is intentionally limited to a region-specific use case.
