What potential issue could arise when using the admin_broadcast function in PHP for reporting events to the administration?

Issue: The potential issue that could arise when using the admin_broadcast function in PHP for reporting events to the administration is that it may not be secure if the input data is not properly sanitized. This could lead to vulnerabilities such as SQL injection or cross-site scripting attacks. To solve this issue, it is important to always sanitize user input before using it in the admin_broadcast function. This can be done by using functions like htmlentities() or htmlspecialchars() to escape special characters and prevent malicious code from being executed.

// Sanitize user input before using admin_broadcast function
$input_data = $_POST['input_data'];
$sanitized_input = htmlspecialchars($input_data);

// Call admin_broadcast function with sanitized input
admin_broadcast($sanitized_input);
