Extended delegated access via unchecked token lifetime
Published Jun 10, 2026 · Updated Jun 10, 2026
Improper input validation in ConnectWise ScreenConnect before 26.2 allows remote authenticated users to create overlong delegated access tokens. The Host Pass creation path fails to enforce the server-side maximum token lifetime when accepting an expiration duration. Host Pass creation privileges are required, and successful exploitation leaves delegated access valid beyond the intended limit, prolonging access to the instance.
