01What is this vulnerability?
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it.

Most of the time this will fill the memory allocated to XWiki and make it unusable every time this document is manipulated. This issue has been patched in XWiki 14.0-rc-1.
