Technical details

An information disclosure vulnerability (CWE-201) exists in the AI Agent job API of Devolutions PowerShell Universal version 2026.2.0. The vulnerability is caused by the insertion of sensitive App Tokens into API responses in plaintext during serialization. An authenticated attacker with 'AI Agent read' permissions can intercept these responses to obtain reusable, potentially higher-privileged authentication tokens. This allows for privilege escalation by reusing the leaked tokens to perform actions as other users or service accounts. The issue is resolved in version 2026.2.1.
