Hi
According to Spring Boot 3 release notes(https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0.0-M5-Release-Notes#actuator-endpoints-sanitization):
Since, the /env and /configprops endpoints can contains sensitive values, all values are always masked by default. This used to be case only for keys considered to be sensitive.
However Actuator API documentation still shows unmasked values (https://docs.spring.io/spring-boot/docs/current/actuator-api/htmlsingle/#env):
"properties" : {
"java.specification.version" : {
"value" : "17"
},
Moreover it doesn't mention new property management.endpoint.env.show-values property that allows to unmask property values.
Another Actuator documentation(https://docs.spring.io/spring-boot/docs/current/reference/html/actuator.html#actuator.endpoints) also doesn't mention new property and how to use it.

The documentation for the show-values property is documented under How-To Guides, Actuator here: https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto.actuator.sanitize-sensitive-values. I agree this might be a bit hard to find since most other actuator configuration properties are documented under https://docs.spring.io/spring-boot/docs/current/reference/html/actuator.html#actuator.endpoints.
