Deeper analysis
XWiki Platform Attachment UI, a component of the generic wiki platform XWiki, contains a stored cross-site scripting vulnerability. Versions from 14.0-rc-1 up to but not including 14.4-rc-1 allow JavaScript to be persisted in an attachment filename; the script executes in the browser of any user who later attempts to move that attachment. The flaw is tracked under CWE-79 and CWE-80 and carries a CVSS 3.1 score of 8.9.
An authenticated user with attachment-creation privileges can upload a file whose name contains executable script. When another user with move rights opens the move dialog for that attachment, the script runs with the victim’s session privileges, enabling theft of sensitive data, account takeover, or other actions within the wiki’s security context.
The project’s security advisory and the associated patch commit state that the issue is fixed in XWiki 14.4-rc-1. Administrators unable to upgrade immediately are advised to copy the template moveStep1.vm into the web application directory and replace the vulnerable code with the version supplied in the patch.
EPSS for the CVE rose from a low baseline after disclosure to a peak of 0.4419 on 2025-12-11 before receding to the current value of 0.2183, indicating a clear increase in observed exploitation interest well after the original publication date.
