CVE-2023-31717: FUXA SQL Injection vulnerability

The vulnerability stems from unsanitized user input being used in SQL queries. The exploit demonstrates SQLi via the 'id' parameter in POST requests, indicating: 1) An endpoint accepts JSON payloads with 'id' 2) This input is directly concatenated into SQL statements 3) No prepared statements or input sanitization exists. While exact code isn't visible, the exploit's payload structure and vulnerability type strongly suggest insecure query construction in API handlers. Node.js SQL injection patterns typically involve string concatenation with user input in db.query() calls.
