Machine-written summary

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

XWiki (xwiki-platform-oldcore) versions from 7.2-milestone-2 up to 16.4.7, from 16.5.0-rc-1 up to 16.10.3, and from 17.0.0-rc-1 up to 17.0.0 are affected. Any user with edit rights on at least one App Within Minutes application can gain programming right and execute remote code by editing the application. Upgrade to XWiki 16.4.7, 16.10.3, or 17.0.0. As a workaround, restrict edit rights on App Within Minutes applications to trusted users, though this may not block every possible exploit.
