Security audit

go-xai

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Go helper for using the xAI API and its sensitive parts are disclosed and scoped to user-directed API use.

Install this only in Go projects where you intend to use xAI/Grok APIs. Keep XAI_API_KEY in environment or secret storage, review the third-party github.com/psyb0t/go-xai dependency before adopting it, and only run upload/delete or cost-incurring API calls on resources you explicitly requested.

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

Tool Parameter Abuse

High
Category
Tool Misuse
Confidence
80% confidence
Finding

Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Finding

This markdown file instructs users to set an Authorization: Bearer <key> header on every request, which involves transmitting sensitive credentials to an external API. The document provides no warning or disclosure about credential sensitivity, key handling, or the privacy implications of sending authenticated requests.
