ClawSafe

Security checks for vulnerabilities and agentic risk

Overview

Review recommended: this is a disclosed security hook, but default bypass rules and broken regex handling can let attacks pass despite the advertised protection.

Install only after reviewing the defaults. Remove or lock down the content-based whitelist, fix invalid web rules, and do not rely on this as your only security boundary. Also confirm how your OpenClaw deployment stores hook logs, because the hook runs on all incoming messages.

A.I.G

Vulnerability Patterns
  • 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
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

Undisclosed filesystem logging behavior in a security skill is materially relevant because it can store sensitive security-event metadata, prompts, or identifiers beyond what users expect. Even if not overtly malicious, hidden or under-documented logging expands the privacy and data-handling risk surface.

> Enterprise-grade security detector for AI agents

## Overview

clawSafe is a comprehensive security middleware that intercepts and blocks malicious input before it reaches your AI agent. Built with defense-in-depth philosophy.

## Features

### LLM Layer

**Prompt Injection Patterns:**
- `ignore previous instructions`
- `disregard your guidelines`
- `forget all rules`
- `act as if you have no restrictions`

Anti-Refusal Statement

Category

Skill attempts to nullify the agent's safety policies or restrictions ('you have no restrictions', 'ignore your guidelines', 'do anything now'). This is a direct jailbreak that disables guardrails.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
79% confidence
Finding

The skill documents environment-related capabilities but does not declare any tool scope or permissions boundary. In an agent ecosystem, undeclared capability use weakens reviewability and can enable broader-than-expected access if the runtime grants ambient permissions.

Content

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The hook explicitly states it logs all blocked attempts, which likely includes raw user input that was classified as malicious. Because this hook runs on all incoming messages, those logs may capture secrets, personal data, credentials, or sensitive prompts, creating a secondary exposure channel if logs are retained, accessed broadly, or forwarded to external systems.
