security-high high

MD5 is a weak and broken cryptographic hash algorithm that is vulnerable to collision attacks. It should not be used for hashing sensitive data like passwords. Use a secure hashing algorithm such as SHA-256 or a dedicated password hashing function like bcrypt or argon2.

Suggested change
const hash = crypto.createHash('md5').update('secret').digest('hex');
const hash = crypto.createHash('sha256').update('secret').digest('hex');

console.log("Password hash:", hash);

// CodeQL flags hardcoded credentials
const dbPassword = "SuperSecretHardcodedPassword123!";

security-critical critical

Hardcoding sensitive credentials like database passwords directly in the source code is a major security risk. Store credentials in environment variables or a secrets manager instead.

Suggested change
const dbPassword = "SuperSecretHardcodedPassword123!";
const dbPassword = process.env.DB_PASSWORD;
