Security audit
Github 1.0.0
Security checks for vulnerabilities and agentic risk
Overview
This is a simple GitHub helper skill that gives examples for using the GitHub CLI and does not add hidden code, persistence, or unrelated behavior.
Before installing, understand that the skill helps an agent use your local GitHub CLI, so any real access depends on your existing `gh` authentication and the permissions of that account. Use it for repositories you intend to manage, and review any mutating `gh` commands before they run.
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
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
