Solr search discloses email addresses of users

Impact

The Solr-based search in XWiki discloses the email addresses of users even when obfuscation of email addresses is enabled. To demonstrate the vulnerability, search for objcontent:email* using XWiki’s regular search interface.

Patches

This has been fixed in XWiki 14.10.15, 15.5.2 and 15.7RC1 by not indexing email address properties when obfuscation is enabled. Further, changing the setting now triggers re-indexing of the affected wiki(s).

Workarounds

We’re not aware of any workarounds.
