🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize the name parameter before processing.
Add input sanitization in the reports controller for the name parameter
Content Security Policy
allImplement a strict Content Security Policy header to mitigate XSS impact.
Add header: Content-Security-Policy: default-src 'self'; script-src 'self'
🧯 If You Can't Patch
- Implement a web application firewall (WAF) with XSS protection rules
- Disable or restrict access to the /common/reports component if not required
🔍 How to Verify
Check if Vulnerable:
Test the /common/reports endpoint by submitting a payload like <script>alert('test')</script> in the name parameter and check if it executes.
Check Version:
php artisan version
Verify Fix Applied:
After patching, repeat the vulnerability test to confirm the payload is properly sanitized and doesn't execute.
