Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain Markdown guide for website image SEO and performance, with no executable code, persistence, credential use, or hidden data movement.

Before installing, understand that this skill may activate on general image-related terms, but its behavior is limited to SEO, accessibility, and web performance guidance. It does not install code or request sensitive access.

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

Finding
The manifest description says to use the skill 'when the user wants to optimize images for search engines and performance' and also matches a long list of common terms such as 'alt text,' 'image captions,' and 'image format.' Several of these phrases are broad enough to appear in routine conversations outside the intended SEO-skill context, and the file does not provide negative examples or exclusions to narrow activation.
