CVE-2026-31151Public exploitNetwork attack vector

Unauthorized dashboard access via cross-portal session reuse

Published Apr 6, 2026 · Updated Apr 6, 2026

Authentication bypass in Kaleris YMS 7.2.2.1 allows remote authenticated users to access the general dashboard through a driver session. The web application maintains separate login URLs for driver and general portals but accepts a driver portal session cookie at /general/home without requesting that portal's credentials. A valid Driver User Role session is required, and the demonstrated consequence is unauthorized access to the general dashboard and its functionality.
