Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed ElevenLabs text-to-speech guide that uses expected audio generation, conversion, and messaging steps, with only minor operational cautions.

Before installing, be aware that text you synthesize may be sent to ElevenLabs and voice notes may be sent through WhatsApp when you invoke that workflow. Verify generated file paths before copying or deleting files, and only send voice messages to intended recipients.

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 (5)

Tool Parameter Abuse

High
Category
Tool Misuse
Confidence
85% confidence
Finding

Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

5. Cleanup:

bash
rm /root/.openclaw/workspace/voice-temp.ogg

WhatsApp requires a non-empty message body to send voice notes. Use a single space as the message.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill documentation instructs the agent to use broad shell access to enumerate files in temporary directories, copy artifacts into the workspace, and remove them afterward. For a TTS skill, this expands behavior beyond narrowly scoped text-to-speech generation and creates opportunity for path confusion, unintended file access, or misuse of exec against files outside the intended output path.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
78% confidence
Finding

This markdown instructs the user/agent to run an rm command to delete a workspace file, but the surrounding text does not include any safety warning beyond calling it 'Cleanup'. Under the markdown criteria for missing user warnings, behaviors that affect user data or system integrity should be disclosed clearly.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

The document presents its primary correctness example using Hebrew text while the rest of the guide is in English, with no indication that users may choose their preferred language or that the example is region-specific. This can be interpreted as an unexplained language/locale preference in natural-language guidance.
