What potential security risks should be considered when implementing a feature for editing database entries in a browser with PHP?

Potential security risks to consider when implementing a feature for editing database entries in a browser with PHP include SQL injection attacks, cross-site scripting (XSS) attacks, and unauthorized access to sensitive data. To mitigate these risks, it is important to validate and sanitize user input, use prepared statements or parameterized queries to prevent SQL injection, and implement proper authentication and authorization mechanisms. 

// Validate and sanitize user input
$editedData = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);

// Use prepared statements to prevent SQL injection
$stmt = $pdo->prepare("UPDATE table SET column = :value WHERE id = :id");
$stmt->bindParam(':value', $editedData['value']);
$stmt->bindParam(':id', $editedData['id']);
$stmt->execute();

// Implement proper authentication and authorization mechanisms
if($_SESSION['user_id'] !== $editedData['user_id']) {
    die("Unauthorized access");
}
