E-commerce Return & Refund Reply

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple Chinese e-commerce reply-template helper with some quality issues, but no hidden execution, credential access, persistence, or destructive behavior.

Use this skill for Chinese-language e-commerce after-sales replies and review the generated message before sending. Remove or hide the internal-notes section from buyer-facing communications, and localize the templates and closing for other languages or marketplaces.

  • 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
91% confidence
Finding

The description says to use the skill for return, exchange, refund inquiries and broadly for "any after-sales consultation," which is wider than the specific refund/return scope implied by the skill name. It does not provide explicit trigger boundaries or negative examples, increasing the chance of unintended invocation for general support chats.

Intent-Code Divergence

Confidence

Finding

The skill contains conflicting instructions: the workflow says to output only one customer-facing message with no meta-commentary, while the output format requires an additional internal-notes section. In practice, this can cause an agent to leak internal classifications, policy checks, or template details to the buyer, creating information disclosure and reliability issues in customer-facing communications.

Natural-Language Policy Violations

Medium

Confidence

Finding

The instruction to always end with the Chinese phrase "如有其他问题,随时联系我们 😊" forces a specific language regardless of the user's language or locale. This can violate language/locale policy when the skill is used in multilingual contexts without user opt-in or a documented region-specific justification.

Finding

This markdown file contains customer-facing reply templates exclusively in Chinese across all issue types. Under the language/locale policy, forcing a specific language without user opt-in or a documented region-specific justification is a natural-language policy violation.
