🔍 How to Verify
Check if Vulnerable:
Check if LoveCardsV2 version is 2.3.2 or earlier and test if /api/upload/image accepts arbitrary file uploads without authentication.Check Version:
Check application configuration files or admin panel for version information.Verify Fix Applied:
Verify that file uploads to /api/upload/image are properly restricted or require authentication.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /api/upload/image
- Uploads of non-image file types (e.g., .php, .jsp)
