Security audit
clawec-shopee-item-hotword
Security checks for vulnerabilities and agentic risk
Overview
This skill is a straightforward Shopee keyword lookup helper that discloses its external ClawEC API use and does not show hidden persistence, credential theft, or unrelated behavior.
Install only if you are comfortable sending Shopee item IDs, site/type parameters, optional dates, and your ClawEC bearer token to clawec.com for keyword analysis. Store the API key in CLAWEC_API_KEY rather than hardcoding it, and review ClawEC's account/API terms for handling of your marketplace data.
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

Missing User Warnings

- Confidence
- 89% confidence
- Finding
This code performs an HTTP POST to an external API and includes both the request payload and a bearer token from an environment variable. The file contains no comment, echo/logging, or prompt disclosing that user-supplied item data will be transmitted to a third-party endpoint.

Natural-Language Policy Violations
Low
- Category
- Not specified by scanner
- Confidence
- 91% confidence
- Finding
The instruction "默认中文报告" specifies a default output language in natural language, but the document does not indicate that users can opt into another language. This can violate a language/locale policy when a skill constrains responses to a specific language without explicit user choice or justification.

Natural-Language Policy Violations
Low
- Category
- Not specified by scanner
- Confidence
- 93% confidence
- Finding
The entire schema and guidance are written as Chinese-only instructions and labels, with no indication that users may choose another language or locale. Under the policy rule for natural-language constraints, this can be considered a language/locale restriction unless explicitly offered as an opt-in or justified as region-specific behavior.

Natural-Language Policy Violations
Low
- Category
- Not specified by scanner
- Confidence
- 95% confidence
- Finding
Usage and validation messages are hardcoded in Chinese, which imposes a specific language on users. Under the policy, locale-specific language should be optional or clearly justified; this file provides no opt-in or documentation for the restriction.
