What are the potential security risks of allowing external access to execute methods in PHP classes?

Allowing external access to execute methods in PHP classes can pose security risks such as unauthorized users being able to call sensitive methods, leading to potential data leaks or manipulation. To mitigate this risk, it is important to restrict access to only trusted sources by implementing proper access controls, such as authentication and authorization checks. 

class MyClass {
    private $secretMethod = "This is a secret method.";

    public function publicMethod() {
        // Code for public method
    }

    private function sensitiveMethod() {
        // Code for sensitive method
    }

    public function executeMethod($methodName) {
        if ($methodName === 'publicMethod') {
            $this->publicMethod();
        } else {
            // Handle unauthorized access
            die("Unauthorized access");
        }
    }
}

$myClass = new MyClass();
$myClass->executeMethod('publicMethod');
