DescriptionCVE.org

Improper control of generation of code ('Code Injection') in the schedule feature in Devolutions PowerShell Universal 2026.2.2 and earlier allows an authenticated user with schedule creation permission to execute arbitrary PowerShell code via crafted schedule parameter names concatenated into a script invocation.

AnalysisAI

Code injection in Devolutions PowerShell Universal 2026.2.2 and earlier allows an authenticated user with schedule creation permission to inject malicious PowerShell code. By crafting parameter names that are unsafe concatenated into a script invocation, an attacker can execute arbitrary commands on the underlying host. No public exploit or active exploitation is currently known, and EPSS indicates low exploit probability (0.29%).

Technical ContextAI

The vulnerability resides in the schedule feature of PowerShell Universal, a web-based IT automation platform. The CWE-94 code injection occurs because user-supplied parameter names are dynamically inserted into PowerShell scripts without proper sanitization or encoding. The CPE designation cpe:2.3:a:devolutions:powershell_universal:*:*:*:*:*:*:*:* confirms the affected component is the PowerShell Universal application itself.

RemediationAI

Upgrade to PowerShell Universal 2026.2.3 or later immediately. This version removes the code injection vector. The official advisory at https://devolutions.net/security/advisories/DEVO-2026-0025/ documents the fix. If an immediate upgrade is not possible, restrict schedule creation privileges to only trusted administrators; note, however, that this reduces but does not eliminate the risk, as malicious schedule parameters could still be injected by any user retaining that permission. There is no workaround that fully mitigates the injection, so patching remains the definitive action.
