Edge Tts

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Edge TTS configuration skill, but users should know automatic mode sends generated reply text to Microsoft TTS services.

Install this only if you are comfortable enabling automatic TTS for OpenClaw replies. Avoid `auto: always` in sensitive chats unless you are allowed to send that text to Microsoft for speech synthesis; choose a different voice if the Chinese default is not appropriate.

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

Findings (4)

Natural-Language Policy Violations

Medium
Confidence
94% confidence
Finding
The documentation and user-facing instructions are written exclusively in Chinese, which effectively forces a specific language on users without any opt-in or alternative. The policy allows locale constraints only when they are explicitly justified or when users are offered a choice, neither of which is present here.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill explicitly relies on Microsoft services for speech synthesis, which means user-provided text is transmitted to a third party, but the documentation does not clearly warn users about that privacy implication. This can lead operators to enable automatic TTS for sensitive chat content without informed consent, increasing the risk of unintended disclosure of personal, confidential, or regulated data.

Natural-Language Policy Violations

Medium
Confidence
94% confidence
Finding
The config hard-codes the TTS voice to "zh-CN-XiaoxiaoNeural", which imposes a specific language/locale selection. Under the policy, locale-specific behavior should offer user choice or be clearly justified as region-specific; this file provides neither.

Natural-Language Policy Violations

Medium
Confidence
96% confidence
Finding
The installation script unconditionally sets the TTS voice to `zh-CN-XiaoxiaoNeural`, which imposes a specific language/locale choice. This matches the policy concern for language or locale constraints without explicit user opt-in or an offered alternative during execution.
