## Overview

### Summary

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.

### Impact

Any CF user holding Space Auditor, Space Manager, or Org Auditor role can access the heap dump, environment, and thread dump actuators for any Steeltoe application in their space. A heap dump contains all in-memory data including database passwords, bearer tokens, and VCAP_SERVICES credentials. CF's `read_sensitive_data` permission, which is specifically designed to gate this access, has no effect.

### Affected configuration

- Application is deployed on Cloud Foundry with CF actuator and security middleware active (added automatically by `AddAllActuators()` when a CF environment is detected).
- The attacker holds a CF role that grants `read_basic_data`: Space Auditor, Space Manager, or Org Auditor.

### Mitigations

If an immediate upgrade is not possible:

- Explicitly set `RequiredPermissions = EndpointPermissions.Full` in the options for `HeapDumpEndpointOptions`, `EnvironmentEndpointOptions`, and `ThreadDumpEndpointOptions`.
- If heap dump, thread dump, or environment are not needed in production, register only the required actuators individually instead of using `AddAllActuators()`.

## Affected packages

- `Steeltoe.Management.Endpoint <= 4.1.0`
- `Steeltoe.Management.EndpointBase <= 3.3.0`

## Remediation

Upgrade to a patched release:

- `Steeltoe.Management.Endpoint 4.2.0`
- `Steeltoe.Management.EndpointBase 3.4.0`
