OpenClaw Exec Safety Validator
Paste any exec command and instantly validate it against OpenClaw's security rules. Detect truncated approvals, carried command injection, argument tampering, and shell wrapper abuse — all in your browser.
Six Security Checks in One Tool
Based on 6 security PRs merged into OpenClaw on May 12, 2026.
Truncation Detection
Catches commands cut off mid-stream — unmatched quotes, unclosed subshells, and trailing operators that could cause partial-execution approval bypasses.
Carried Command Detection
Finds piggybacked commands hiding behind semicolons, && / || chains, backtick substitutions, $() expansions, and pipes to shell interpreters.
Argument Safety Validation
Validates arguments against safe-bin rules: path traversal (../), null byte injection, flag injection via double-dash, and dynamic linker overrides.
Plugin Entry Scanning
Scans for plugin runtime patterns that escape the plugin boundary — directory traversal, symlink references, and dynamic code evaluation.
Shell Wrapper Integrity
Enforces that bash -c wrapper payloads match the approved command exactly. Detects chained payloads, eval calls, exec replacements, and env overrides.
Auth Context Awareness
Flags commands that require authentication profiles — CDP relay access, remote debugging ports, browser automation tools, and sandbox browser operations.
Validate Your Command
Paste an exec command or try one of the examples to see which checks pass or fail.

Frequently Asked Questions
What does the Exec Safety Validator check?
The validator runs six security checks based on OpenClaw PRs merged on May 12, 2026: truncation detection (PR #81001), carried command detection (#81000), safe-bin argument validation (#80999), plugin runtime entry scanning (#80998), shell wrapper payload matching (#80978), and auth context requirements (#81002). Each check mirrors the server-side validation OpenClaw performs before approving exec commands.
Why would a command be rejected?
Commands are rejected when they contain patterns that could allow unintended execution — for example, a semicolon followed by a second command, unmatched quotes that suggest the command was truncated before a dangerous suffix, or path traversal sequences that escape the intended directory. These patterns are the exact attack vectors that the OpenClaw security PRs were designed to block.
Does this tool send my commands to a server?
No. All validation runs entirely in your browser using client-side JavaScript. Your commands never leave your machine — no network requests, no logging, no telemetry. You can verify this by disconnecting from the internet and using the tool offline.
What is the difference between this and the Exec Policy Auditor?
The Exec Policy Auditor helps you configure approval policies — per-channel modes, allow/block lists, and sandbox rules. This Exec Safety Validator tests individual commands against the low-level validation rules that run after policy matching. Think of the Policy Auditor as configuring the rules, and this validator as testing commands against those rules.
Can I use this to debug why OpenClaw rejected my command?
Yes — that is the primary use case. Paste the exact command that was rejected and the validator will tell you which specific check failed (truncation, carried command, argument injection, etc.) along with a concrete explanation and fix suggestion.
Are the detection patterns identical to OpenClaw's server-side checks?
The patterns are based on the same security logic described in the merged PRs, but this is a simplified client-side approximation. OpenClaw's server-side validation may have additional context-dependent checks, rate limiting, and state tracking that a stateless browser tool cannot replicate. Use this as a first-pass diagnostic, not a guarantee.
