August 18, 2023

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any user who can view Invitation.WebHome can execute arbitrary script macros including Groovy and Python macros that allow remote code execution including unrestricted read and write access to all wiki contents. This vulnerability has been patched on XWiki 14.4.8, 15.2-rc-1, and 14.10.6. Users are advised to upgrade. Users unable to upgrade may manually apply the patch on Invitation.InvitationCommon and Invitation.InvitationConfig, but there are otherwise no known workarounds for this vulnerability.
