Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
XWiki Platform's xwiki-platform-oldcore is vulnerable across several version ranges before 14.10.21, 15.5.5 and 15.10.6. A user who has edit but not view right on a page can delete it and replace it with new content without delete right, though the source says it does not appear possible to use this to gain additional rights. Upgrade to 14.10.21, 15.5.5, 15.10.6 or a later release; no workaround is known.
