Security audit

JEP Guard

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local execution gate that can block and audit integrated actions only when the operator explicitly enables full mode.

Install this only if you want a local policy gate that can deny OpenClaw hook calls in full mode. Review and protect ~/.jep-guard, provision keys and allowed-skills.json yourself, keep audit logs secure, and do not treat this repair-candidate release as a fully verified sandbox or security certification.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • 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

Finding

Static analysis repeatedly indicates the implementation performs functions unrelated to simple configuration/inspection, including active runtime service behavior and security decisioning. Such under-disclosure increases the chance of unsafe deployment because defenders and users cannot accurately assess trust boundaries from the manifest.
