Security audit

文生图 Seedream 4.5

Security checks for vulnerabilities and agentic risk

Overview

The skill provides a coherent cloud image-generation workflow with clearly disclosed uploads, authentication, and local API-key storage.

Use prompts and images you are comfortable sending to dLazy, review generation costs, and protect or revoke your API key as needed. The external CLI and its claimed key-storage protections were not audited in this review.

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
93% confidence
Finding

The supplied code performs login rather than text-to-image or image-to-image generation. Authentication could be a supporting implementation detail, but this chunk provides no evidence that dlazy login supports the declared Seedream workflow. The assessment is limited to the supplied chunk; it does not establish credential theft or other malicious behavior.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
90% confidence
Finding

Authentication can be a supporting implementation detail, but the supplied content consists solely of a login command and shows no connection to Seedream or image generation. As supplied, its observable purpose differs from the declared purpose. The command alone does not establish credential theft or other malicious behavior.

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.
