4. Test application thoroughly after removal

🔧 Temporary Workarounds

Input validation and sanitization

all

Implement strict input validation to reject unexpected object properties and sanitize user inputs.

Object.freeze on prototypes

all

Freeze Object.prototype to prevent prototype pollution attacks.

Object.freeze(Object.prototype);

🧯 If You Can't Patch

  • Implement network segmentation to isolate affected systems
  • Deploy web application firewall with prototype pollution detection rules

🔍 How to Verify

Check if Vulnerable:

Check package.json or package-lock.json for 'akbr-update' version 1.0.0, or run: npm list akbr-update

Check Version:

npm list akbr-update

Verify Fix Applied:

Verify akbr-update is no longer in package.json and npm list shows no akbr-update package installed

📡 Detection & Monitoring

Log Indicators:

  • Unusual object property modifications
  • Application crashes with prototype-related errors
  • Unexpected property assignments in logs

Network Indicators:

  • HTTP requests with unusual object structures in payloads
  • Requests containing __proto__ or constructor properties

SIEM Query:

source=web_logs AND ("__proto__" OR "constructor" OR "prototype") AND status=200
