🚨 Severity: HIGH
πŸ’‘ Vulnerability: The TriggerKit automation executor's openURL step allowed execution of any URL scheme. This meant that malicious or untrusted automations could execute .app files or scripts via the file:// scheme, or manipulate system settings via x-apple.systempreferences:, bypassing the app sandbox when passing those strings to NSWorkspace.shared.open.
🎯 Impact: Attackers could craft automations that break out of app boundaries to run arbitrary local code or manipulate macOS system preferences.
πŸ”§ Fix: Rather than breaking legitimate automation functionality using a strict allowlist (e.g. shortcuts://), an explicit security blocklist was added to reject inherently dangerous schemes (file, x-apple.systempreferences) in both the runtime executor (AutomationExecutor.swift) and the validation phase (AutomationProgram+Validation.swift). Security comments were added to explain this defense.
βœ… Verification: Ran testing simulations, statically verified test suites, requested AI code review, and performed pre-commit reflections.

πŸ‘‹ Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a πŸ‘€ emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.
