Caution Review failedThe pull request is closed. WalkthroughThe changes introduce a StopForumSpam API integration to the spam protection logic, update code formatting for consistency across several files, and adjust default configuration values and versioning in the package manifest. No public interfaces or method signatures were altered, and no logic changes were made outside the spam protection enhancement. Changes

2-2: Skip formatting change
The added blank line is a non-functional formatting adjustment.package.yml (1)

15-17: Nonce attribute formatting consistency
Refactored to use spaced concatenation for thenonceattribute. Behavior is unchanged.
34-36: Nonce attribute formatting consistency
Mirrored the same formatting improvements for the<script>tag.ytemplates/classic/value.spam_protection.tpl.php (2)
15-16: LGTM! Style improvement for consistency.The added spacing after commas in the
method_existscall improves readability and maintains consistent code style.
34-35: LGTM! Consistent style formatting.Good consistency with the previous
method_existscall formatting.lib/yform/value/spam_protection.php (3)
9-13: LGTM! Improved code style consistency.The spacing improvements around type casts and string concatenation enhance readability.
20-20: LGTM! Consistent null comparison style.Using

🛠️ Refactor suggestion
Consider implementing caching for StopForumSpam API responses.
The current implementation makes an API call on every form submission, which could impact performance and may hit rate limits. Consider implementing a caching mechanism to store results for a reasonable time period (e.g., 1 hour).
Consider adding a caching layer:
// Check cache first
$cache_key = 'stopforumspam_' . md5($_SERVER['REMOTE_ADDR']);
$cached_result = rex_config::get('yform_spam_protection', $cache_key);
$cache_time = rex_config::get('yform_spam_protection', $cache_key . '_time', 0);
if ($cache_time > (time() - 3600)) { // 1 hour cache
$is_spam = $cached_result;
} else {
// Make API call and cache result
// ... API call logic ...
rex_config::set('yform_spam_protection', $cache_key, $is_spam);
rex_config::set('yform_spam_protection', $cache_key . '_time', time());

In lib/yform/value/spam_protection.php around lines 74 to 86, the code calls the
StopForumSpam API on every form submission, which can degrade performance and
risk hitting rate limits. To fix this, implement a caching mechanism that stores
the API response for each IP address for about one hour. First, generate a cache
key based on the IP, then check if a cached result exists and is still valid
(within the last hour). If valid, use the cached result; otherwise, perform the
API call, parse the response, and store the result and current timestamp in the
cache for future use.
Critical security and performance issues in StopForumSpam integration.
The StopForumSpam API integration has several concerning issues:
- Security: Using HTTP instead of HTTPS exposes requests to interception
- Reliability:
file_get_contents()lacks timeout configuration and proper error handling - Performance: Blocking HTTP requests during form validation will slow down user experience
- XML Security: No validation before parsing potentially malicious XML content
- Error Handling: Missing error handling for network failures and malformed responses
Apply this diff to address the security and reliability concerns:
- if (trim((string) rex_config::get('yform_spam_protection', 'use_stopforumspam'), '|')) {
- $result = file_get_contents('http://api.stopforumspam.org/api?ip=' . $_SERVER['REMOTE_ADDR']);
- if ($result) {
- $doc = new DOMDocument();
- $doc->loadXML($result);
- if ('yes' == $doc->getElementsByTagName('appears')[0]->nodeValue) {
- $this->params['warning'][$this->getId()] = $this->params['error_class'];
- $this->params['warning_messages'][$this->getId()] = '{{ use_stopforumspam_ip_is_locked }}';
- $log[] = 'Die IP Adresse ist gesperrt.' . rex_request($this->getFieldId());
- rex_logger::factory()->log('info', 'Stop Forum Spam' . $_SERVER['REMOTE_ADDR'], [], __FILE__, __LINE__);

In lib/yform/value/spam_protection.php lines 74 to 86, replace the HTTP URL with
HTTPS to secure the API request, switch from file_get_contents() to a cURL
request with a timeout and error handling to avoid blocking and improve
reliability, validate the XML response before parsing to prevent XML injection
attacks, and add try-catch or conditional checks to handle network failures and
malformed responses gracefully without breaking the form validation flow.
