CVE-2025-22235: 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
