XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. The
modifications rest endpoint does not filter out entries according to the user's rights. Therefore, information hidden from unauthorized users are exposed though the
modifications rest endpoint (comments and page names etc). Users should upgrade to XWiki 14.6+, 14.4.3+, or 13.10.8+. Older versions have not been patched. There are no known workarounds.
