XWiki Platform vulnerable to privilege escalation via properties with wiki syntax that are executed with wrong author
XWiki Platform is a generic wiki platform. Starting in version 13.10, it's possible to use the right of an existing document content author to execute a text area property. This has been patched in XWiki 14.10, 14.4.7, and 13.10.11. There are no known workarounds.
All versions starting from 13.10 before 13.10.11, all versions starting from 14.0 before 14.4.7, all versions starting from 14.5 before 14.10
Upgrade to versions 13.10.11, 14.4.7, 14.10 or above.
