54-54: Verify the removal of attributes parameter.The removal of parameters from
recaptcha_html()call aligns with the PR's security objectives. However, we should verify that this doesn't break existing functionality.✅ Verification successful
Based on the shell script results, I can now provide a final response:
The removal of attributes parameter is safe and consistent with the codebase
The verification shows that:
- The
recaptcha_html()method in the parent class (WP_reCaptcha) has an optional$attrparameter with default empty array:function recaptcha_html( $attr = array() )- Most usages across the codebase call the method without parameters through
print_recaptcha_html()- The change in
class-wp_recaptcha_cforms2.phpaligns with the common pattern in the codebaseThe removal of the parameter is safe because:
- The parameter is optional by design
- The parent class handles empty attributes gracefully
- This change follows the consistent pattern used throughout the codebase
🏁 Scripts executed
The following scripts were executed for the analysis:

🛠️ Refactor suggestion
Consider sanitizing method parameters.
The get_request method accepts parameters that could potentially contain unsafe data. Consider sanitizing these inputs for enhanced security.
Apply this diff to add sanitization:
- public function get_request($input_id, $input_classes, $input_title) {
+ public function get_request($input_id, $input_classes, $input_title) {
+ $input_id = sanitize_html_class($input_id);
+ $input_classes = sanitize_html_class($input_classes);
+ $input_title = sanitize_text_field($input_title);
+
$wp_recaptcha = WP_reCaptcha::instance();
$request = $wp_recaptcha->begin_inject(true);
$request.= $wp_recaptcha->recaptcha_html( );Committable suggestion was skipped due to low confidence.
