Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS). It's possible to exploit the restore template to perform a XSS, e.g. by using URL such as:
/xwiki/bin/view/XWiki/Main?xpage=restore&showBatch=true&xredirect=javascript:alert(document.domain)
This vulnerability exists since XWiki 9.4-rc-1.
The vulnerability has been patched in XWiki 14.10.5 and 15.1-rc-1.
It's possible to workaround the vulnerability by editing the template restore.vm to perform checks on it, but note that the appropriate fix involves new APIs that have been recently introduced in XWiki. See the referenced jira tickets.

Both vulnerabilities about the delete and restore templates have been reported by René de Sain @renniepak.
