Security audit

GitHub CLI

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward GitHub CLI helper with disclosed, user-directed repository, issue, pull request, and release workflows.

Install this only if you want the agent to use your authenticated GitHub CLI. Review requested gh actions before execution, especially repo creation, issue or PR comments, PR merges, releases, deletes, or force-push-related work.

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

Finding

The manifest description says to trigger for requests to 'use gh, manage GitHub repos, PRs, or issues from the CLI,' which is broad and does not define clear boundaries or exclusions. While GitHub is domain-specific, the activation scope still lacks specificity about when this skill should or should not activate among many common repository-management requests.
