XWiki Platform vulnerable to cross-site scripting in target parameter via share page by email

Impact

Users are able to forge an URL with a payload allowing to inject Javascript in the page (XSS).
For instance, the following URL execute an alter on the browser: <xwiki-host>/xwiki/bin/view/Main/?viewer=share&send=1&target=&target=%3Cimg+src+onerror%3Dalert%28document.domain%29%3E+%3Cimg+src+onerror%3Dalert%28document.domain%29%3E+%3Crenniepak%40intigriti.me%3E&includeDocument=inline&message=I+wanted+to+share+this+page+with+you., where <xwiki-host> is the URL of your XWiki installation.
See https://jira.xwiki.org/browse/XWIKI-20370 for me details.

Patches

The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.4, and 14.4.8.

Workarounds

The fix is only impacting Velocity templates and page contents, so applying this patch is enough to fix the issue.
