29-45: Consider enhancing error handling in the constructor.While the error handling is good, consider throwing a specific exception instead of using
trigger_error()since this is a critical initialization step.try { rex_dir::create($this->tmpFolder); } catch (Exception $e) { - // Log the exception or handle it as needed - trigger_error('Error creating temp directory: ' . $e->getMessage(), E_USER_WARNING); - // Possibly throw another exception or return an error message - return; + throw new RuntimeException('Failed to create temporary directory: ' . $e->getMessage(), 0, $e); }
Line range hint
71-80: Consider using uniqid for temporary files.Using a fixed filename ('temp.zip') could lead to race conditions in concurrent uploads. Consider using a unique filename.
-$tmpFile = $this->tmpFolder . '/temp.zip'; +$tmpFile = $this->tmpFolder . '/' . uniqid('upload_', true) . '.zip';
Line range hint
95-113: Consider using GitHub API for branch detection.Instead of trying main/master branches sequentially, consider using the GitHub API to get the default branch name.
if ($branch) { $downloadUrl = "https://github.com/$owner/$repo/archive/refs/heads/$branch.zip"; } else { - // Try main/master branch - $downloadUrl = "https://github.com/$owner/$repo/archive/refs/heads/main.zip"; - // If main doesn't exist, try master - if (!$this->isValidUrl($downloadUrl)) { - $downloadUrl = "https://github.com/$owner/$repo/archive/refs/heads/master.zip"; - } + // Get default branch from GitHub API + $apiUrl = "https://api.github.com/repos/$owner/$repo"; + $context = stream_context_create(['http' => [ + 'method' => 'GET', + 'header' => ['User-Agent: REDAXOZipInstall'] + ]]); + if ($response = @file_get_contents($apiUrl, false, $context)) { + $repoData = json_decode($response, true); + $defaultBranch = $repoData['default_branch'] ?? 'main'; + $downloadUrl = "https://github.com/$owner/$repo/archive/refs/heads/$defaultBranch.zip"; + } }
Line range hint
185-191: Enhance package.yml validation.Consider validating more fields in package.yml to ensure addon compatibility.
/** @var array{package: string, version: string} $config */ // Read package.yml $config = rex_file::getConfig($extractPath . $packageFile); -if (empty($config['package'])) { +if (empty($config['package']) || empty($config['version']) || !preg_match('/^\d+\.\d+(\.\d+)?(-\w+)?$/', $config['version'])) { throw new Exception(rex_i18n::msg('zip_install_invalid_addon')); }
Line range hint
330-344: Enhance URL validation.Consider adding more robust URL validation including scheme and protocol checks.
protected function isValidUrl(string $url): bool { + // Validate URL format first + if (!filter_var($url, FILTER_VALIDATE_URL)) { + return false; + } + + // Check if scheme is allowed + $scheme = parse_url($url, PHP_URL_SCHEME); + if (!in_array($scheme, ['http', 'https'], true)) { + return false; + } + try { /** @var array<int, string>|false $headers */ $headers = @get_headers($url);
Line range hint
1-367: Consider implementing caching for GitHub API responses.To improve performance and reduce API calls, consider implementing a caching mechanism for GitHub API responses. This could be particularly beneficial for the repository listing functionality.
Key points to consider:
- Cache GitHub API responses with a reasonable TTL
- Implement cache invalidation on error responses
- Use REDAXO's caching mechanism if available

20-28: LGTM! Well-documented properties with proper type declarations.The property declarations follow PHP 7.4+ typed properties best practices with appropriate PHPDoc comments.
59-61: LGTM! Proper type annotation for uploaded file.The array type annotation for
$uploadedFilecorrectly defines the structure of the$_FILESarray.

@coderabbiai add Check rate limit from response headers |

@coderabbitai add MIME type validation |
|
Tip For best results, initiate chat on the files or code changes. @skerbis Below is an example of how you could add MIME type validation within the /**
* Validates whether the file at $filePath has a ZIP MIME type.
*
* @param string $filePath Path to the uploaded file.
* @return bool True if the file is recognized as a ZIP file, false otherwise.
*/
protected function isValidZipMimeType(string $filePath): bool
{
if (!function_exists('finfo_open')) {
// As a fallback, you might use file extension checks or handle errors differently.
return preg_match('/\.zip$/i', $filePath) === 1;
}
$finfo = new finfo(FILEINFO_MIME_TYPE);
$mimeType = $finfo->file($filePath);
// Add or remove MIME types that your environment recognizes for ZIP archives
$validZipMimeTypes = [
'application/zip',
'application/octet-stream',
'application/x-zip-compressed',
];
return in_array($mimeType, $validZipMimeTypes, true);
}Where to call this method
public function handleFileUpload(): string
{
// ... existing code ...
$uploadedFile = $_FILES['myfile'] ?? null; // adjust to your setup
if (!$this->isValidZipMimeType($uploadedFile['tmp_name'])) {
return 'Invalid file type! Please upload a valid ZIP archive.';
}
// Proceed with installation...
// ...
}This approach ensures that only files recognized as ZIP archives will proceed to the next steps. You can expand the validation rules by adding additional MIME types or performing extra checks (e.g., verifying the file extension, scanning for malicious content) depending on your needs. |
