🛡️ Automated Security Fix

Vulnerability Fixed:

• File: src\components\LoginForm.jsx
• Line: 79
• Type: code_quality
• Severity: Low
• Description: Sensitive data in localStorage

Fix Summary:
The vulnerability involved storing sensitive user data (email) redundantly in localStorage. The fix removes the unnecessary localStorage.setItem('userEmail', ...) calls from all authentication handlers (handleGoogleSignIn, handleSignUp, handleSignIn), as the email is already stored within the userInfo object. This change eliminates the redundant data, reduces the attack surface for potential XSS vulnerabilities, and improves code maintainability.

Changes Made:

• Removed redundant storage of user.email in localStorage.
• Consolidated user information into a single userInfo object in localStorage to minimize data exposure and adhere to the DRY (Don't Repeat Yourself) principle.

Security Impact:
Resolving this code quality issue improves security by reducing the application's attack surface. Storing the user's email address in multiple localStorage keys unnecessarily exposes sensitive information. If the application were vulnerable to a Cross-Site Scripting (XSS) attack, an attacker could more easily harvest this data. By consolidating user information into a single object, we minimize this risk and make the code cleaner and less prone to inconsistencies.

Code Changes Preview:

-       for (let i = 0; i < 20; i++) {
+       for (let i = 0; i  carts, [carts]);
-         cartElements.push({
+ 
-           id: i,
+   useEffect(() => {
-           left: Math.random() * 100 + "vw",
+     let strength = 0;
-           animationDuration: Math.random() * 3 + 2 + "s",
+     if (formData.password.length >= 8) strength++;
-           animationDelay: Math.random() * 2 + "s",
+     if (/[A-Z]/.test(formData.password)) strength++;
-         });
+     if (/[0-9]/.test(formData.password)) strength++;
-       }
+     if (/[^A-Za-z0-9]/.test(formData.password)) strength++;
-       setCarts(cartElements);
+     setPasswordStrength(Math.min(strength, 4));
-     };
+     console.log("Password Strength:", strength);
