Information disclosure in the AI Agent job API in Devolutions PowerShell Universal 2026.2.0 allows remote authenticated users to obtain App Tokens. The API serializes App Tokens in plaintext into job responses instead of withholding reusable authentication material. AI Agent read access is required; exposed tokens can be reused under their assigned, potentially higher privileges.
