In today’s digital landscape, broken authentication remains a critical vulnerability, especially in frameworks like Laravel. It can expose sensitive user data and compromise entire systems. This blog explores how broken authentication occurs in Laravel, provides a coding example, and highlights how to detect such issues using tools like our free Website Security checker.
Broken authentication occurs when the system fails to properly secure user authentication processes. This might involve:
Weak password management policies.
Session hijacking vulnerabilities.
Misconfigured authentication mechanisms.
In Laravel applications, these issues often arise due to improper use of built-in authentication libraries or failing to implement additional security measures.
Insufficient Session Management:
Using default session expiration times or storing session data insecurely can expose apps to session fixation attacks.
Weak Password Policies:
Not enforcing strong passwords leaves the app open to brute-force attacks.
Misconfigured Authentication Guards:
Laravel's guard system can lead to vulnerabilities if not correctly configured.
Let’s walk through a simple coding example to mitigate broken authentication vulnerabilities in a Laravel app.
Enforcing Strong Password Policies
To enforce strong passwords, update the validation rules in your RegisterController:
use Illuminate\Support\Facades\Validator;
protected function validator(array $data) {
return Validator::make($data, [
'name' => ['required', 'string', 'max:255'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
'password' => [
'required',
'string',
'min:8',
'regex:/[a-z]/', // At least one lowercase letter
'regex:/[A-Z]/', // At least one uppercase letter
'regex:/[0-9]/', // At least one number
],
]);
}
Preventing Session Fixation
Ensure sessions are securely managed by regenerating session IDs after login:
use Illuminate\Support\Facades\Auth;
public function authenticated(Request $request, $user) {
Auth::logoutOtherDevices($request->password);
session()->regenerate();
}
You can easily identify broken authentication issues in your Laravel application using our free Website Security checker. This tool scans your website and provides a comprehensive vulnerability assessment report.
After scanning your Laravel app, download the vulnerability assessment report to identify specific authentication flaws.

Use Multi-Factor Authentication (MFA):
Laravel supports MFA using packages like Laravel Fortify.
Limit Login Attempts:
Add rate-limiting to your login route to block brute-force attacks.
use Illuminate\Support\Facades\RateLimiter;
RateLimiter::for('login', function (Request $request) {
return Limit::perMinute(5)->by($request->ip());
});
Keep Laravel and Dependencies Updated:
Regularly update your Laravel installation to address known vulnerabilities.
Broken authentication in Laravel is a significant threat, but with proper measures, you can secure your application. Use strong password policies, session management, and tools like our free Website Security checker to identify and resolve vulnerabilities.
