Details

org.xwiki.platform:xwiki-platform-skin-skinx vulnerable to basic Cross-site Scripting by exploiting JSX or SSX plugins ### 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](https://github.com/xwiki/xwiki-platform/commit/fe65bc35d5672dd2505b7ac4ec42aec57d500fbb) and rebuilding and redeploying `xwiki-platform-skin-skinx`. ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira](http://jira.xwiki.org) * Email us at [Security ML](mailto:security@xwiki.org)
