Warning

Description: Log Injection occurs when untrusted user input is directly written to log files without proper sanitization. This can allow attackers to manipulate log entries, potentially leading to security issues like log forging or cross-site scripting. To prevent this, always sanitize user input before logging by removing or encoding newline characters, using string encoding functions, and leveraging built-in sanitization features of logging libraries when available.

Severity: High

[amazon-q-developer]

The fix involves using a sanitizeLog function (from an imported sanitize-log package) to sanitize user input before logging, preventing potential log injection vulnerabilities.

Suggested change

	console.error(`[INFO] Connecting to MySQL: ${this.host}, Database: ${this.database}`);
	// Import the sanitize-log package for log sanitization
	async init(): Promise<void> {
	try {
	console.error(`[INFO] Connecting to MySQL: ${sanitizeLog(this.host)}, Database: ${sanitizeLog(this.database)}`);
	this.connection = await mysql.createConnection(this.config);
	console.error(`[INFO] MySQL connection established successfully`);
	} catch (err) {
	console.error(`[ERROR] MySQL connection error: ${sanitizeLog((err as Error).message)}`);
	throw new Error(`Failed to connect to MySQL: ${sanitizeLog((err as Error).message)}`);
	}
	}
