PW version displayed on the backend login screen

[er314]

this one is trivial

feature request : PW should not disclose its version number to unauthenticated users on the backend login screen.

ok, this is about security through mere obscurity, so nothing vital here, but experience tells that attackers really love to easily know the exact version of their target.

If there were (known) vulnerabilities, this would be more important, but +1 from me for changing this behaviour anyway. In my opinion there's absolutely no need to disclose the specific version number

[er314]

Yes, here it's more about general good practice.

Imagine that tomorrow a security flaw is discovered in current PW (2.7.2 and older). So, the day after tomorrow , PW 2.7.3 is released, fixing the flaw. So everyone upgrades to 2.7.3. But if some site is not upgraded, then it is at risk. And, as PW discloses its version number, the attackers will be happy

It's basically that in both admin theme's default.php files:

Makes sense to me, I'll move that <?php endif; ?> down one line, so that the name/version only appears when logged in.

Once an update was made, the version number gets visible again due the notification message
