Cross-Site Request Forgery (CSRF) allowing to delete or rename tags

Impact

It's possible with a simple request to perform deletion or renaming of tags without needing any confirmation, by using a CSRF attack.

Patches

The problem has been patched in XWiki 13.10.7, 14.4.1 and 14.5RC1.

Workarounds

It's possible to patch existing instances directly by editing the page Main.Tags and add this kind of check, in the code for renaming and for deleting:

#if (!$services.csrf.isTokenValid($request.get('form_token')))
    #set ($discard = $response.sendError(401, "Wrong CSRF token"))
#end

See the commit with the fix for more information about patching the page: https://github.com/xwiki/xwiki-platform/commit/7fd4cda0590180c4d34f557597e9e10e263def9e
