Machine-written summary

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

The xwiki-platform-oldcore Maven package, versions 14.5 to before 14.10 and 14.4.1 to before 14.4.7, exposes a Document script API that returns author objects which can be set on a document. An attacker who can run scripts in XWiki can use this to assign arbitrary authors to a document, and subsequent script executions then check rights against that author. Upgrade to version 14.10 or 14.4.7. The source lists no workaround other than upgrading.
