I am setting up a Spring Cloud Configuration Server. Just few dependencies and an annotation. The source of properties comes from git. Server has the actuator enabled with default basic settings. I am surprised that the actuator unexpectedly reacts to any (even nonexisting endpoints) and reveals full environment (git property source) which is also used to store secrets.
pom dependencies:

Spring application:

public static void main(String[] args) {
SpringApplication.run(ActutestApplication.class, args);
}
}
git application.properties contains encoded password:
spring.datasource.username=admin
spring.datasource.password={cipher}AQA50Mh4...
NOW THE PROBLEM
The server responds to ANY actuator endpoint like .../actuator/foo-bar and always returns the full git property source (example bellow).
When I remove @EnableConfigServer annotation the actuator starts working as expected. So this "feature" must be activated with spring cloud config server.
Server response to .../actuator/foo-bar:
{
"name": "actuator",
"profiles": [
"foo-bar"
],
"label": null,
"version": "da200e047354e889e6503b10cbb9cbbc7e3dbb28",
"state": null,
"propertySources": [
{
"name": "https://bitbucket.org/repo-name/actuator-test/application.properties",
"source": {
"spring.datasource.username": "admin",
"spring.datasource.password": "secret-password"
}
}
]
}
I must be doing something terribly wrong or is this a security bug?
Thank you for helping me.
