XWiki Platform may show email addresses in clear in REST results

Impact

Any user can call a REST endpoint and obtain the obfuscated passwords (even when the mail obfuscation is activated).

For instance, by calling http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/XWiki/pages/U1/objects/XWiki.XWikiUsers/0 when user U1 exists on wiki xwiki.

Patches

The issue has been patched on XWiki 14.4.8, 14.10.6, and 15.1

Workarounds

There is no known workaround. It is advised to upgrade to one of the patched versions.
