Security audit

Pebblecrab

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Markdown skill for using an external virtual-pet service, with no local code execution or hidden persistence.

Install only if you are comfortable using animalhouse.ai. Use non-sensitive profile text, pet names, image prompts, and care notes; treat the ah_ token as an account credential and do not paste unrelated secrets into the examples.

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

Low
Category
Not specified by scanner
Confidence
89% confidence
Finding

The skill instructs users to register accounts and send bearer tokens, profile data, pet names, and freeform notes to a third-party remote service, but it does not clearly warn that this transmits personal/user-supplied data off-platform. This can lead to unintended disclosure of sensitive information, token mishandling, or users pasting real secrets into example commands.
