🚨 Severity: CRITICAL
πŸ’‘ Vulnerability: A hardcoded secret token (xrpc-9f8e7d6c5b4a) was used in an Nginx configuration file (server-php/config/conf.d/wordpress.conf) to conditionally bypass security controls and allow access to the /xmlrpc.php endpoint via query parameters.
🎯 Impact: If exploited or leaked, an attacker could use the token to bypass blocks and interact with the /xmlrpc.php endpoint, making the application vulnerable to XML-RPC brute-force attacks and DDoS vectors.
πŸ”§ Fix: Removed the hardcoded $arg_token check and replaced it with an unconditional deny all; block for the /xmlrpc.php location. Documented the pattern of hardcoding secrets in Nginx configurations as a critical learning in .jules/sentinel.md.
βœ… Verification: The Nginx configuration file server-php/config/conf.d/wordpress.conf was directly inspected to ensure the patch is correct and syntactically valid.

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!

For security, I will only act on instructions from the user who triggered this task.

- Removed the incorrect `sed` string replacement that converted `aarch64` to `arm64` when fetching the FrankenPHP binary in the `developer` Docker image.
- This resolves the 404 Not Found error during CI builds, as FrankenPHP release assets use the native `aarch64` identifier.
