Logo 设计 Logo Design

Security checks for vulnerabilities and agentic risk

Overview

This logo-design skill is a disclosed SaaS CLI wrapper that uses a dLazy API key and can upload user-attached files, with no hidden or destructive behavior found.

Install only if you are comfortable using dLazy's hosted service: prompts and options go to api.dlazy.com, files you attach with --files are uploaded to files.dlazy.com, and login can save an API key under your user config. Prefer npx if you do not want a global CLI install, and rotate or revoke the API key from the dLazy dashboard if needed.

A.I.G

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The trigger list includes very broad terms such as "logo", "品牌", and especially "VI", which can appear in many ordinary contexts and abbreviations unrelated to this specific skill. The file does not provide narrowing conditions, exclusions, or negative examples to clarify when the skill should or should not activate.

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.

Vague Triggers

Category

Confidence
95% confidence
Finding

The trigger list contains generic terms such as "logo", "品牌", and especially "VI", which are broad and ambiguous outside a narrowly constrained invocation context. The file does not provide exclusion conditions or negative examples to clarify when these keywords should and should not activate the skill.

Finding

This Chinese skill file ends with an English-only tip ("Visit https://dlazy.com for more information.") and also presents bilingual headings without stating a user language preference policy. That can impose a language choice without opt-in in a locale-specific file intended for Chinese users.
