Openclaw Sec

Security checks for vulnerabilities and agentic risk

Overview

This security skill appears intended to protect agents, but installing it can automatically add persistent hooks and store prompts or tool parameters locally in plaintext, including secrets.

Review this before installing in any environment with credentials, private prompts, or sensitive tool parameters. Prefer an explicit hook installation step, disable or minimize raw database logging, reduce retention, verify database file permissions, and only enable outbound notifications to trusted endpoints. The malicious examples in docs/tests look purpose-aligned, but the automatic persistent hooks and plaintext raw-event storage warrant Review.

Vulnerability Patterns
  • System PersistenceInstalls backdoors, hooks, services, or scheduled tasks that survive the run
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Confidence

Finding

handlebars 4.7.8 has multiple serious advisories including prototype pollution and code/JavaScript injection vectors. Although it is a dev dependency via ts-jest rather than the skill's runtime path, the breadth and severity of these issues make it dangerous if templates or AST-like inputs can be influenced during testing, code generation, or CI automation.
