Security audit

Arcane

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small Arcane PHP microframework guide with no evidence of hidden credential access, network activity, persistence, or unsafe automatic execution.

Before installing, treat it as a coding-assistance skill for Arcane PHP projects. Review any edits it proposes to project files, especially configuration files like .env, but the inspected package does not show hidden or disproportionate behavior.

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

Confidence

Finding
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Confidence
85% confidence
Finding
The skill describes project creation and maintenance tasks around a PHP framework and explicitly references sensitive project files and code structure, yet it declares no tool restrictions. In an agent environment, omitting allowed-tools or permissions can enable unnecessary file read/write behavior beyond the minimum required scope, increasing the chance of unintended modification or access to project files.
