A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

1const owner = req.query.owner;2const rows = await db.query(3  "SELECT * FROM files WHERE owner = '" + owner + "'"4);

1const owner = req.query.owner;2const rows = await db.query(3  "SELECT * FROM files WHERE owner = $1",4  [owner]5);
