CVE-2026-84869 is a missing-authorization condition in the client-side file-transfer handling of ConnectWise ScreenConnect Support and Access sessions prior to version 26.6.5. Under certain circumstances, file-transfer actions in an active remote session can be processed without proper authorization or Host confirmation, allowing files to be transferred to and executed on the Host client, including through elevated execution actions. ScreenConnect servers are not affected. The issue is also associated with CWE-269, Improper Privilege Management.
