Technical details
A code injection vulnerability (CWE-94) exists in the variables feature of Devolutions PowerShell Universal versions 2026.2.2 and earlier. The root cause is improper escaping of variable values when they are written to the variables configuration file. An authenticated attacker with 'variable write' permissions can provide a specially crafted variable value that, when processed, executes arbitrary PowerShell code in the context of the application. This allows for full remote code execution on the host. The issue is resolved in version 2026.2.3.
