Code Injection in PowerShell Universal Settings Management

Improper control of generation of code ('Code Injection') in the settings feature in Devolutions PowerShell Universal 2026.2.3 and earlier allows an authenticated user with settings management permission to execute arbitrary PowerShell code via a crafted setting value that is not properly escaped when written to the settings configuration file.

Casky was already ahead

This CVE exploits attack patterns that Casky's 322matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

This vulnerability is a code injection flaw (CWE-94) in Devolutions PowerShell Universal 2026.2.3 and earlier that allows authenticated users with settings management permissions to execute arbitrary PowerShell code. By crafting malicious setting values that bypass proper escaping when written to the configuration file, attackers can achieve remote code execution with the privileges of the PowerShell Universal service. This is particularly dangerous because it requires only legitimate access credentials and settings modification rights—a realistic threat in environments where administrative delegation is common. Organizations running affected versions of PowerShell Universal face significant risk, especially if service accounts have elevated privileges or if the application processes sensitive data.

Casky's 322 mapped skills leverage Claude's extended reasoning to detect the attack patterns underlying this vulnerability across MITRE ATT&CK's Initial Access (TA0001) and Execution (TA0043) tactics. Practitioners using Casky would identify suspicious activity through detection of: unescaped or specially-crafted setting parameter values being written to configuration files; unusual PowerShell command execution originating from the Universal service context; and configuration file modifications followed by code execution events. The platform's skill-based approach maps these behavioral indicators to known code injection techniques, allowing security teams to spot both pre-exploitation reconnaissance (attempting to enumerate settings permissions) and post-exploitation execution patterns (verifying successful code injection). This multi-layer detection approach helps teams distinguish legitimate configuration changes from weaponized payloads.
