Security audit

语音合成 豆包 Doubao TTS

Security checks for vulnerabilities and agentic risk

Overview

The skill’s speech-generation commands fit its clearly disclosed cloud processing, login, and installation requirements.

Use this skill if you are comfortable sending your text to dLazy and paying its generation charges. Review the pinned CLI before installation, avoid submitting confidential material without checking the service’s privacy terms, and protect or revoke any saved API key.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied chunk contains only a login command. It does not process text, invoke a TTS model, or generate audio. Authentication could support a TTS implementation, but this chunk provides no evidence connecting dlazy login to that purpose.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied code performs a login operation rather than speech synthesis. Authentication could support a TTS workflow, but the chunk provides no evidence that dlazy login authenticates to Doubao or otherwise supports the declared purpose. No credential theft or other downstream behavior can be established from this command alone.

Category
MCP Tool Poisoning
Confidence
85% confidence
Finding

The supplied chunk contains no identifiable text-to-speech operation, Doubao integration, text input handling, or audio output. Instead, it delegates to an unspecified CLI command. CLI execution could support TTS, but the provided code does not establish that connection. The package's internal behavior cannot be determined from this snippet.

MCP Tool Poisoning
Confidence
82% confidence
Finding

The supplied chunk contains no identifiable speech-synthesis operation, text input handling, or Doubao integration. It instead provides a generic external CLI invocation. An external CLI could support the declared purpose, but neither its command nor its implementation is supplied, so that connection is not established. The package's internal behavior and any additional side effects cannot be determined from this chunk.

Whitespace Padding

Medium
Category
Prompt Injection
Confidence
70% confidence
Finding

Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.
