Security audit

B2A

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill about making products usable by AI agents; it is coherent and non-executable, though users should add stronger consent and privacy safeguards before implementing the commerce patterns.

Safe to install as guidance material. Before implementing its autonomous purchasing or tracking examples, require explicit user authorization, spending and quantity caps, clear notifications, easy cancellation, scoped credentials, and privacy controls for user and agent identifiers.

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

Missing User Warnings

Finding

The skill explicitly recommends tracking per-query analytics tied to an agent_id, selection status, and conversion outcomes, but provides no privacy boundaries, retention limits, minimization guidance, or disclosure expectations. This creates a realistic risk of unnecessary profiling, cross-session correlation, and collection of identifiable or pseudonymous agent/user behavior data beyond what is needed for service operation.

Missing User Warnings

Confidence

Finding

The skill promotes autonomous reordering ('No human decision point') without any guardrails around user consent, approval thresholds, cancellation, or clear disclosure that purchases may occur automatically. In a retail/ecommerce context this increases the risk of unauthorized or unexpected purchases, especially if downstream agents implement the pattern literally.

Missing User Warnings

Confidence
91% confidence
Finding

The subscription API example includes persistent identifiers like user_id and agent_id and creates recurring purchasing behavior, but it omits privacy, consent, and authorization safeguards. Without guidance on minimization, authentication, scoped tokens, and user approval for subscription creation, implementers could expose personal data and enable unauthorized recurring orders.
