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. During extraction, these paths may cause files to be written outside the intended extraction directory. The issue has been addressed by implementing ZIP archive entry path validation to prevent extraction outside the designated directory.
