Exposure of Resource to Wrong Sphere
spring-boot versions prior to version v2.2.11.RELEASE was vulnerable to temporary directory hijacking. This vulnerability impacted the `org.springframework.boot.web.server.AbstractConfigurableWebServerFactory.createTempDir` method. NOTE: This vulnerability only affects products and/or versions that are no longer supported by the maintainer.

Symlink privilege escalation attack via Spring Boot launch script
Spring Boot supports an embedded launch script that can be used to easily run the application as a systemd or init.d linux service. The script included with Spring Boot is susceptible to a symlink attack which allows the `run_user` to overwrite and take ownership of any file on the same system. In order to instigate the attack, the application must be installed as a service and the `run_user` requires shell access to the server.

Spring Boot EndpointRequest.to() creates wrong matcher if actuator endpoint is not exposed
EndpointRequest.to() creates a matcher for null/** if the actuator endpoint, for which the EndpointRequest has been created, is disabled or not exposed.

Your application may be affected by this if all the following conditions are met:

  *  You use Spring Security
  *  EndpointRequest.to() has been used in a Spring Security chain configuration
  *  The endpoint which EndpointRequest references is disabled or not exposed via web
  *  Your application handles requests to /null and this path needs protection


You are not affected if any of the following is true:

  *  You don't use Spring Security
  *  You don't use EndpointRequest.to()
  *  The endpoint which EndpointRequest.to() refers to is enabled and is exposed
  *  Your application does not handle requests to /null or this path does not need protection

Spring Boot Actuator denial of service vulnerability
In Spring Boot versions 2.7.0 - 2.7.17, 3.0.0-3.0.12 and 3.1.0-3.1.5, it is possible for a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition.

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

*  the application uses Spring MVC or Spring WebFlux
*  `org.springframework.boot:spring-boot-actuator` is on the classpath
