1. Review the GitHub repository for any updates. 2. Implement input validation and output encoding. 3. Consider upgrading if newer version exists.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize budget parameter input
Implement regex filtering: /^[a-zA-Z0-9\s.,$€£¥]+$/ for budget values
Output Encoding
allEncode all user-controlled output before rendering in HTML
Use HTML entity encoding: < for <, > for >, & for &, " for ", ' for '
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in budget parameter
- Disable or restrict access to vulnerable functionality until patched
🔍 How to Verify
Check if Vulnerable:
Test by injecting <script>alert('XSS')</script> into budget parameter and check if script executesCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Attempt same XSS payload and verify it's properly sanitized or blocked📡 Detection & Monitoring
