Security audit

Asr Claw

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent speech-to-text tool, but users should be aware that cloud engines can send audio to third-party services and the install downloads an external executable.

Before installing, confirm you trust the GitHub release source for the downloaded executable. Use local engines for private or regulated recordings, and choose cloud engines only when you are comfortable sending the audio to that provider under its policies. Review the default language setting if Chinese is not your expected default.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The trigger list includes generic conditions such as 'User wants to transcribe audio, speech, or voice to text' and 'User needs speech recognition or ASR' without narrowing context or exclusion conditions. In a markdown skill description, this can cause the skill to match many ordinary requests too broadly and makes it unclear when the skill should not activate.

Missing User Warnings

Medium
Category

Confidence
96% confidence
Finding

The cloud-engine examples instruct users to send audio to OpenAI, Doubao, and Deepgram without an explicit warning that the audio leaves the local machine and is transmitted to third-party services. In a speech-transcription skill, audio may contain sensitive personal, corporate, or regulated data, so omission of this disclosure increases the risk of unintended privacy and compliance violations.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
90% confidence
Finding

The configuration declares default_lang with a default of zh, and the examples and flag table also reinforce Chinese as the default. This is a locale preference imposed by default rather than chosen by the user, which can conflict with language/locale policy expectations unless explicitly justified or opt-in.
