Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Spring Boot versions from 3.4.0 before 3.4.5, from 3.3.0 before 3.3.11, and the older affected lines listed in the advisory are vulnerable. When Spring Security's EndpointRequest.to() is used for an actuator endpoint that is disabled or not exposed over the web, it builds a matcher for /null/**, so the security rule may not protect the intended endpoint. The impact applies only if the application handles requests to /null and that path needs protection. Upgrade to Spring Boot 3.4.5 or 3.3.11, or to a patched release on your line.
