WWBN AVideo is an open source video platform. In 29.0 and earlier, an unauthenticated remote attacker can read arbitrary image files anywhere on disk that the PHP user can open — including private user-profile photos that the application's normal serving wrappers gate behind ACLs, admin-uploaded thumbnails, encrypted-video poster frames, and image content under sibling-app directories reachable via .. traversal. The endpoint requires no authentication.

Affected: Packagist: WWBN/AVideo

### Summary The endpoint requires **no authentication**. An unauthenticated remote attacker can read arbitrary image files anywhere on disk that the PHP user can open — including private user-profile photos that the application's normal serving wrappers gate behind ACLs, admin-uploaded thumbnails, encrypted-video poster frames, and image content under sibling-app directories reachable via `..` traversal.

### Details `view/img/image404Raw.php` reads the `image` GET parameter and joins it directly into a filesystem path served via `readfile()`. `view/img/image404Raw.php` (full file, current `master` @ `0dbadbcaaa1b415c7db078a72dc4b26d9fac0485`):

```php <?php

// Fetch requested image URL $imageURL = !empty($_GET['image']) ? $_GET['image'] : $_SERVER["REQUEST_URI"]; $rootDir = dirname(__FILE__) . '/../../'; if ($imageURL == 'favicon.ico') { $imgLocalFile = "{$rootDir}/videos/{$imageURL}"; } else { $imgLocalFile = "{$rootDir}/{$imageURL}"; // ← attacker-controlled }

if (file_exists($imgLocalFile)) { $imageInfo = getimagesize($imgLocalFile); // ← format gate if (empty($imageInfo)) { die('not image'); } // …extension → Content-Type mapping… header("HTTP/1.0 200 OK"); header('Content-Type: ' . $type); header('Content-Length: ' . filesize($imgLocalFile)); readfile($imgLocalFile); // ← exfil bytes exit; } ```

Issues:

1. **No authentication.** The file is reachable via direct GET; no `require` of `globals.php`, no session…
