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 MVC Applications Path Traversal Vulnerability
Spring Framework MVC applications can be vulnerable to a “Path Traversal Vulnerability” when deployed on a non-compliant Servlet container.

An application can be vulnerable when all the following are true:

  *  the application is deployed as a WAR or with an embedded Servlet container
  *  the Servlet container  does not reject suspicious sequences https://jakarta.ee/specifications/servlet/6.1/jakarta-servlet-spec-6.1.html#uri-path-canonicalization 
  *  the application  serves static resources https://docs.spring.io/spring-framework/reference/web/webmvc/mvc-config/static-resources.html#page-title  with Spring resource handling


We have verified that applications deployed on Apache Tomcat or Eclipse Jetty are not vulnerable, as long as default security features are not disabled in the configuration. Because we cannot check exploits against all Servlet containers and configuration variants, we strongly recommend upgrading your application.

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.
