Amendment

Overview
org.springframework:spring-webflux is a Spring Framework module that contains support for reactive HTTP and WebSocket clients as well as for reactive server web applications including REST, HTML browser, and WebSocket style interactions.
Affected versions of this package are vulnerable to Missing Authorization allowing Spring Security authorization rules to be bypassed for static resources.
Note:
Non-Static Resources Are Not Affected by this vulnerability. This is because handlers for these routes use predicates to validate the requests even if all security filters are bypassed.
Spring Security states that for this to impact an application, all of the following conditions must be met:
It must be a WebFlux application.
It must be using Spring's static resources support.
It must have a non-permitAll authorization rule applied to the static resources support.
