The potential security risk associated with the provided PHP code for deleting articles in this forum thread is the lack of input validation, which can lead to SQL injection attacks. To solve this issue, we need to use prepared statements to safely execute SQL queries. 

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=forum', 'username', 'password');

// Prepare the SQL query using a prepared statement
$stmt = $pdo->prepare("DELETE FROM articles WHERE id = :id");

// Bind the parameter
$stmt->bindParam(':id', $_POST['article_id']);

// Execute the query
$stmt->execute();
