概要

Impact

There was no check in the author of a JavaScript xobject or StyleSheet xobject added in a XWiki document, so until now it was possible for a user having only Edit Right to create such object and to craft a script allowing to perform some operations when executing by a user with appropriate rights.

Patches

This has been patched in XWiki 14.9-rc-1 by only executing the script if the author of it has Script right.

Workarounds

The only known workaround consists in applying the following patch and rebuilding and redeploying xwiki-platform-skin-skinx.
