Voice Wake Say

Security checks for vulnerabilities and agentic risk

Overview

The skill mainly does voice output, but it can send assistant response text to a third-party TTS service even though it is framed as local macOS speech.

Review this before installing if assistant replies may include private, business, legal, medical, or credential-related information. Use it only if you are comfortable with fallback speech sending response text to the listed third-party API, or configure/modify it to remain local-only.

Findings (10)

Description-Behavior Mismatch

Medium
Confidence
86% confidence
Finding
The skill metadata presents the capability as local macOS speech output, but the body also authorizes a cloud TTS fallback that transmits response text off-device. That mismatch can cause operators and users to underestimate data exposure and makes the skill riskier than advertised.

Context-Inappropriate Capability

Medium
Confidence
89% confidence
Finding
A skill whose stated purpose is local use of macOS `say` does not clearly need a remote TTS service and API-key handling to function. Adding external transmission expands the attack surface and creates confidentiality risk for spoken assistant content, especially if responses may contain sensitive user data.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The fallback explicitly sends `SPOKEN_TEXT` to an external API without any visible requirement to warn the user or obtain consent. Because assistant replies can include personal or confidential information, this creates a meaningful privacy and compliance risk.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The documented fallback sends assistant response text to a third-party TTS endpoint without requiring explicit user consent or a clear runtime privacy warning. Because spoken text may contain sensitive user data, this creates a real data-exposure risk whenever local `say` is unavailable.

    json={"type": "tts", "inputs": {"text": SPOKEN_TEXT, "voice": "alloy"}, "prefer": "balanced"},
Confidence
83% confidence
Finding
This finding duplicates the same outbound request location and reflects the same underlying issue: the skill sends data to an external service during fallback operation. In context, the risk comes from off-device disclosure of response text rather than from the mere existence of network code.

    timeout=60,
Confidence
80% confidence
Finding
The hardcoded external API endpoint confirms that the skill is designed to contact a remote service. In this skill context, that makes the behavior more dangerous because the feature is marketed as local speech synthesis, yet it can disclose spoken content to a third party.

    json={"type": "tts", "inputs": {"text": SPOKEN_TEXT, "voice": "alloy"}, "prefer": "balanced"},
Confidence
90% confidence
Finding
The `requests.post(...)` call is an intentional network transmission to a third-party service, making the finding valid rather than a false positive. Because the skill is designed to speak assistant output for voice interactions, sending that output off-device broadens the privacy and compliance risk surface.

Confidence
88% confidence
Finding
The hardcoded external endpoint confirms that response text is sent to a remote service outside the local machine. In a voice-assistant skill, users may reasonably expect audio generation to remain local, so this undisclosed off-device transfer is security-relevant.
