Security audit

语音合成 Gemini 2.5 TTS

Security checks for vulnerabilities and agentic risk

Overview

The skill’s speech-generation instructions, dLazy authentication, and cloud data transfers are clearly disclosed and fit its purpose.

Use text and files you are comfortable sending to dLazy, review its privacy terms and credit costs, and protect the saved organization API key. The pinned npx option avoids a global CLI installation. This assessment covers the skill instructions, not a full audit of the external CLI or hosted service.

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
Findings (3)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied code performs a login operation rather than generating audio. Authentication could support a TTS implementation, but nothing in this chunk establishes that relationship. The visible behavior therefore does not match the declared purpose.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied code performs a login operation rather than audio generation. Although authentication can be a supporting implementation detail, this chunk provides no evidence that dlazy login supports the declared Gemini text-to-speech purpose. The command's underlying authentication behavior cannot be determined from this snippet.

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.
