Drupal Security Review Skill

Purpose

Use this skill to perform focused security reviews for Drupal 11 custom modules and themes.

When to apply

• Reviewing pull requests before merge.
• Auditing custom code for common web vulnerabilities.
• Preparing release readiness checks.

Review checklist

1. Input handling: Validate and sanitize all external input.
2. Output escaping: Escape output in Twig and PHP render logic.
3. Database safety: Use query builder or placeholders in all SQL operations.
4. Access control: Confirm route, entity, and operation permissions are enforced.
5. Secrets and config: Ensure credentials are never committed and sensitive config is protected.

Common anti-patterns to flag

• Direct SQL string concatenation with user data.
• Unescaped raw markup in render arrays.
• Trusting $_GET, $_POST, or request payloads without validation.
• Debug leftovers (var_dump, kint, dpm) in production paths.

Useful validation commands

rg "(var_dump|dpm\(|kint\()" web/modules/custom web/themes/custom
rg "\$_(GET|POST|REQUEST)" web/modules/custom web/themes/custom
