Security audit

Alvis Next.js Framework

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Next.js guidance skill with no executable code, persistence, or hidden high-impact behavior.

This skill appears safe to install as a lightweight Next.js assistant. Users should still review generated auth or production code before applying it, and treat the external setup-guide link as outside the reviewed artifact.

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 'Use When' guidance is broad and generic, which can cause the agent to invoke it in many loosely related developer-workflow situations without clear boundaries. In an automation context, over-broad routing increases the chance of inappropriate use, irrelevant code generation, or unsafe application to sensitive tasks such as auth or production changes without sufficient task-specific checks.
