Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The xwiki-platform-livedata-livetable Maven package, which is part of XWiki Platform's Live Data Live Table connector, is vulnerable in versions before 16.10.17, from 17.0.0-rc-1 before 17.4.10, from 17.5.0-rc-1 before 17.10.4, and from 18.0.0-rc-1 before 18.1.0-rc-1. Any user who can edit a page can use the Live Data edit REST API to change that page's rights and gain script right, allowing them to run Velocity scripts and send unfiltered HTML and JavaScript to clients. Upgrade to 16.10.17, 17.4.10, 17.10.4, or 18.1.0-rc-1 or later; no workaround other than upgrading is known.
