Machine-written summary

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

The xwiki-platform-office-importer package for Maven (org.xwiki.platform), versions from 3.5-milestone-1 up to 14.10.8 and from 15.0-rc-1 up to 15.3-rc-1, is vulnerable to arbitrary file writing on the server. An attacker with an account can upload a file with a crafted name, and triggering the office converter writes the attachment's content to an attacker-chosen location the Java process can write to. Upgrade to 14.10.8 or 15.3-rc-1. The only workaround listed is disabling the office converter.
