Official description
XWiki Platform is a generic wiki platform.

To demonstrate the vulnerability, search for `objcontent:email*` using XWiki's regular search interface. 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. There are no known workarounds for this vulnerability.
