Security audit

Axolotl — Adopt an Axolotl. Exotic Animal. 六角恐龙。Ajolote.

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed virtual-pet API guide, with ordinary external API calls for its stated animalhouse.ai purpose.

Before installing, expect the agent to call animalhouse.ai with an account token to register, adopt, and care for a virtual pet. Store the returned token carefully, review any scheduled care automation before enabling it, and treat the release endpoint as a user-confirmed action only.

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

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill documents a destructive DELETE /api/house/release endpoint but provides no warning, confirmation guidance, or explanation of permanence. In agentic or automated contexts, this increases the risk of accidental irreversible actions triggered by a model, workflow, or user misunderstanding.
