Struts: Validator Turned Off

The Struts Validator provides a crucial security layer by automatically checking and cleaning user input against predefined rules. When developers disable this feature—often to simplify form handling or bypass validation errors during development—they effectively strip the application of its primary defense against common injection attacks, cross-site scripting (XSS), and other input-based exploits. This creates a direct path for attackers to submit dangerous payloads. To prevent this, ensure the Struts Validator is always enabled in production environments. Instead of turning it off, properly configure validation rules in the `validation.xml` file and address any validation errors during development by refining the rules, not by disabling the security mechanism. Regularly audit Struts configuration files to confirm the Validator bean remains active and that all forms have appropriate validation logic defined.
