Security audit

Nextjs

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Next.js guidance skill with no executable code, persistence, credential access, or hidden behavior in the inspected artifact.

Before installing, treat this as a lightweight Next.js drafting aid and review any generated application code before deployment, especially authentication, caching, and production configuration changes. The main improvement would be clearer task scoping in the skill text.

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

Finding

The skill's invocation guidance is vague and effectively permits use for broad 'developer workflow work' without clearly defining boundaries, prerequisites, or excluded tasks. Overly broad routing criteria can cause the agent to apply this skill in unintended contexts, increasing the chance of generating unsafe code, inappropriate automation, or low-relevance outputs for security-sensitive engineering tasks.
