A malicious attacker can inject arbitrary SQL code into your Oracle database, potentially leading to unauthorized data access or modification.
Implement parameterized queries using PreparedStatement or CallableStatement with ‘?’ placeholders for user-input values. Additionally, consider the following best practices: Validate and sanitize all user input on the server-side; Use stored procedures instead of dynamic SQL queries; Limit access privileges to the bare minimum required by your application; Consider applying whitelisting or blacklisting techniques to restrict malicious code execution.
