Security audit

Mistral Pet

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple set of documented commands for using an external virtual-pet API, with no hidden local execution or persistence found.

Install only if you intend to use animalhouse.ai for a virtual pet. The API calls are disclosed and purpose-aligned, but treat the ah_ bearer token like a password, avoid pasting it into shared logs or screenshots, and review the external service before using personal information in the profile or pet notes.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Missing User Warnings

Category
Not specified by scanner
Confidence
86% confidence
Finding

The skill instructs users to save a bearer token but does not warn that tokens can leak through shell history, terminal logs, screenshots, CI logs, or copied commands. Exposed bearer tokens could let anyone with access interact with the user's pet account and associated data until the token is revoked or rotated.
