Security audit

Coupon

Security checks for vulnerabilities and agentic risk

Overview

This is a simple coupon-shopping guidance skill with no executable code, persistence, credential handling, or hidden behavior in the inspected artifact.

Installers should understand that this skill is a Chinese-language coupon and shopping-deal prompt. Its main limitation is broad, generic example phrasing; use it for explicit coupon or shopping discount tasks and verify prices, return terms, and seller trust before purchasing.

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

Confidence
91% confidence
Finding

The example trigger phrases are generic meta-questions about how to use the skill and its capabilities, which could be matched by ordinary user speech unrelated to an explicit coupon workflow. Overly broad activation increases the chance of accidental invocation, unintended context capture, or the skill steering conversations when the user did not clearly intend to use it.

Natural-Language Policy Violations

Finding

Natural-language policy issues can arise when a skill effectively forces a single language without user opt-in. This file presents the skill name, description, examples, and usage notes only in Chinese, with no indication that users may choose another language or that the skill is intentionally limited to a Chinese-language audience.
