📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, privilege escalation to administrator, site defacement, or full system takeover if database permissions allow file system access.
Likely Case
Unauthorized access to customer data (names, emails, addresses), order history, and potentially sensitive user information stored in the database.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, with database user having minimal necessary permissions.
🎯 Exploit Status
Exploitation requires authenticated access with at least Subscriber role. SQL injection is well-understood with many available tools.
