Security audit

Authentication

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only authentication workflow skill with no hidden execution, data access, or persistence behavior.

Installers should expect this skill to help structure authentication-related planning and reviews. It does not add executable behavior or access data, but users may want to invoke it only when they actually want a structured authentication workflow.

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 activation guidance says to offer the workflow when a user mentions "authentication or closely related work," which is broad and leaves the boundary of related work undefined. Without narrower scope, explicit examples, or exclusions, this could cause the skill to be invoked for common security discussions that are not actually asking for this workflow.
