Description

Spring MVC and WebFlux applications that obtain a data-binding Errors instance with HTML escaping enabled and then render field errors using the no-argument Errors.getFieldErrors() or Errors.getFieldError() accessors are vulnerable to arbitrary HTML/JavaScript code injection, potentially resulting in a reflected cross-site scripting (XSS) vulnerability.
