Affected packages

• Maven org.xwiki.platform:xwiki-platform-skin-skinx: >= 3.0-milestone-1, < 14.9-rc-1 → fixed in 14.9-rc-1

Description

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`.
