ImpactSimple users can create global SSX/JSX without specific rights: in theory only users with Programming Rights should be allowed to create SSX or JSX that are executed everywhere on a wiki. But a bug allow anyone with edit rights to actually create those.PatchesThis issue has been patched in XWiki 13.10-rc-1, 12.10.11 and 13.4.6.WorkaroundsThere's no easy workaround for this issue, administrators should upgrade their wiki.Referenceshttps://jira.xwiki.org/browse/XWIKI-19155For more informationIf you have any questions or comments about this advisory:Open an issue in [JIRA](https://jira.xwiki.org)Email us at [XWiki Security ML](mailto:security@xwiki.org)
