CVE-2026-16798Network attack vector

OAuth token disclosure via unfiltered job responses

Published Jul 24, 2026 · Updated Jul 24, 2026

Sensitive-data exposure in Devolutions PowerShell Universal 2026.2.2 and earlier allows remote authenticated users to obtain OAuth refresh tokens. The automation jobs API serializes job-read responses without removing a stored OAuth refresh token associated with another user's job. Scoped read permission for the job or its script is required, and the disclosed token grants access associated with the token's OAuth authorization.
