// SECURE: The '?' or '$1' placeholders prevent SQL injection const query = 'SELECT * FROM hunts WHERE species_name = $1'; const values = [userInput]; // The payload you provided would be treated as a literal string, not code. db.query(query, values, (err, res) => { // Handle results safely }); Use code with caution. Copied to clipboard 3. Key Functionalities
Automatically fetch local water temperature and tide data based on the user's GPS coordinates at the time of the hunt.
Ensure depth_meters is a number and species_name doesn't contain forbidden characters.
Instead of building queries by concatenating strings (which leads to the injection vulnerability you shared), use a structured schema and . Table: hunts
