What is CVE-2026-84858?

ScadaLTS 2.8.1-release-candidate build 0 contains a critical vulnerability that allows authenticated users to execute arbitrary code remotely. The vulnerability arises from the exposure of the 'validateScript' method in the DWR 'DataSourceEditDwr' class, which compiles and executes JavaScript supplied by attackers using the Rhino scripting engine. This lack of authorization checks permits users with low privileges to exploit this flaw, bypassing DWR routing controls and gaining unauthorized code execution capabilities.
