Coding Buddy

Security checks for vulnerabilities and agentic risk

Overview

This is a simple virtual-pet API guide that discloses its external service use and does not contain hidden local execution or persistence.

Before installing, be aware that using the examples sends registration and pet-care data to animalhouse.ai. Treat the returned ah_ token like a password and store it outside source control or shared logs.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

85% confidence
Finding

Mixing characters from multiple Unicode scripts in a single identifier is a common technique to create visually ambiguous tool names.

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The skill instructs users to obtain and use a bearer token, notes that it is shown once, but does not explicitly warn that the token is sensitive or should not be committed, logged, or shared. In a coding-oriented skill, users may paste commands into terminals, shell history, scripts, or repos, increasing the chance of credential leakage and subsequent unauthorized access to the pet account/API.
