GHSA-vvp7-r422-rx83

### Impact

It's possible to list some users who are normally not viewable from subwiki by requesting users on a subwiki which allows only global users with `uorgsuggest.vm`. This issue only concerns hidden users from main wiki.
Note that the disclosed information are the username and the first and last name of users, no other information is leaked.

### Patches

The problem has been patched on XWiki 13.10.8, 14.4.3 and 14.7RC1.

### Workarounds

It's possible to workaround this vulnerability by patching directly `uorgsuggest.vm ` to apply the same changes as in https://github.com/xwiki/xwiki-platform/pull/1883.
