⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of user sessions, credential theft, and full control over the application interface leading to data exfiltration or further attacks.
Likely Case
Session hijacking, credential theft, and unauthorized actions performed on behalf of authenticated users.
If Mitigated
Limited impact with proper input validation and output encoding, potentially reduced to minor data leakage.
🎯 Exploit Status
Exploitation requires user interaction with malicious URLs but the vulnerability is straightforward to exploit once discovered.

Test if data: URLs can bypass the validation by attempting to input data:image/svg+xml,<svg onload=alert(1)> in URL fieldsCheck Version:
Check package.json or application version informationVerify Fix Applied:
Verify that data: URLs and other dangerous schemes are properly blocked by the validation logic📡 Detection & Monitoring
Log Indicators:
- Unusual URL patterns containing data: scheme
- Multiple failed validation attempts
Network Indicators:
