Upstream source 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. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.25.RELEASE and earlier
