I created the patch here: https://gerrit.openbmc-project.xyz/c/openbmc/bmcweb/+/29344 and I am looking for feedback. While REST D-Bus does expose many useful APIs, and phosphor-webui depends heavily on it, it does leak information to any logged in user. This comes to the question, should we prefer functionality by default or security by default? It is a compile switch either way, so each user can still decide which they prefer. I have the opinion that the default should be the safest configuration, and if someone wants to change that, then they can accept the risk and change the build flag.

I would as well. This is why I would like to see the webui patches upstreamed.

Is anyone planning on opening a CVE?
