Summary
SharePoint Products CopyMove for SharePoint 2019 and CopyMove for SharePoint V6 contain a path traversal flaw in their ZIP import feature. A user with low privileges who can reach that feature locally, and whose action is required to trigger it, can supply a crafted ZIP archive that writes files outside the intended extraction directory, which can alter files on the system.

Read the original description
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.
