SharePoint Products CopyMove before 2026-11-06 allows traversal. An authenticated SharePoint user with the necessary permissions to use the ZIP import functionality may exploit a path traversal vulnerability in CopyMove for SharePoint 2019 and CopyMove for SharePoint V6 by supplying a crafted ZIP archive. A path traversal vulnerability in the ZIP import functionality of SharePoint Products ApS CopyMove for SharePoint 2019 and CopyMove for SharePoint V6 allows a user with access to the ZIP import functionality to supply a crafted ZIP archive containing malicious entry paths.
