Spring MVC and WebFlux has Server Sent Event stream corruption
Spring MVC and WebFlux applications are vulnerable to stream corruption when using Server-Sent Events (SSE). This issue affects Spring Foundation: from 7.0.0 through 7.0.5, from 6.2.0 through 6.2.16, from 6.1.0 through 6.1.25, from 5.3.0 through 5.3.46.

Spring Framework Path Traversal vulnerability
Applications serving static resources through the functional web frameworks WebMvc.fn or WebFlux.fn are vulnerable to path traversal attacks. An attacker can craft malicious HTTP requests and obtain any file on the file system that is also accessible to the process in which the Spring application is running.

Path traversal vulnerability in functional web frameworks
Applications serving static resources through the functional web frameworks WebMvc.fn or WebFlux.fn are vulnerable to path traversal attacks. An attacker can craft malicious HTTP requests and obtain any file on the file system that is also accessible to the process in which the Spring application is running.

Specifically, an application is vulnerable when both of the following are true:

  *  the web application uses RouterFunctions to serve static resources
  *  resource handling is explicitly configured with a FileSystemResource location


However, malicious requests are blocked and rejected when any of the following is true:

  *  the  Spring Security HTTP Firewall https://docs.spring.io/spring-security/reference/servlet/exploits/firewall.html  is in use
  *  the application runs on Tomcat or Jetty

Spring Framework Improper Path Limitation with Script View Templates
Use of Java scripting engine enabled (e.g. JRuby, Jython) template views in Spring MVC and Spring WebFlux applications can result in disclosure of content from files outside the configured locations for script template views. This issue affects Spring Framework: from 7.0.0 through 7.0.5, from 6.2.0 through 6.2.16, from 6.1.0 through 6.1.25, from 5.3.0 through 5.3.46.
