CVE-2026-50201: Steeltoe's sensitive actuators (heapdump/env) only require Restricted permission
All Steeltoe actuator endpoints default to EndpointPermissions.Restricted, which is mapped 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.
