Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. In Steeltoe.Management.Endpoint prior to version 4.2.0 and Steeltoe.Management.EndpointCore prior to version 3.4.0, all Steeltoe actuator endpoints default to `EndpointPermissions.Restricted`, which is mappeds to Cloud Foundry's `read_basic_data` permission (granted to Space Auditors and similar low-trust roles). Sensitive actuators including heap dump, environment, and thread dump do not raise this to `EndpointPermissions.Full`, so CF's `read_sensitive_data` permission flag is not enforced for those endpoints. Spring Boot's equivalent Cloud Foundry integration gates these endpoints with `read_sensitive_data` by default. Steeltoe.Management.Endpoint 4.2.0 and Steeltoe.Management.EndpointCore 3.4.0 patch the issue. If an immediate upgrade is not possible, explicitly set `RequiredPermissions = EndpointPermissions.Full` in the options for `HeapDumpEndpointOptions`, `EnvironmentEndpointOptions`, and `ThreadDumpEndpointOptions`; and/or if heap dump, thread dump, or environment are not needed in production, register only the required actuators individually instead of using `AddAllActuators()`.
