The security review of the hu_general theme has identified that the theme follows Drupal security best practices with no critical security vulnerabilities.

• No raw output filters: No use of |raw filter that could bypass XSS protection
• No unsafe escaping: No manual escaping that could introduce vulnerabilities
• Proper variable output: All variables are properly escaped by default through Twig's auto-escaping
• No dynamic includes: No dynamic template inclusion that could lead to file inclusion vulnerabilities

• All layout templates (html.html.twig, page templates)
• All node templates (hc-page, hc-article, hc-person, hc-resource, hc-standard-homepage, hc-announcement)
• All teaser templates
• Navigation templates (breadcrumb, menu)
• Block templates
• Media templates
• Views templates
• Field templates
• Search templates
• Global include templates (header, footer, utility menus, content headers)

• No dynamic code execution: No use of eval(), exec(), system(), shell_exec(), or passthru()
• No file inclusion vulnerabilities: No dynamic include() or require() statements
• No deserialization risks: No use of unserialize() on untrusted data
• Input validation: Theme settings form implements proper validation
• No direct superglobal access: No direct access to $_GET, $_POST, or $_REQUEST

• hu_general.theme - Theme hook implementations
• theme-settings.php - Theme settings form and validation

• Input validation: Admin script field properly validates textarea input
• Form API usage: Uses Drupal's Form API for secure form handling
• Access control: Theme settings only accessible to users with proper permissions
