CVE-2026-6706Network attack vectorHinoki check available

Authenticated vault documentation disclosure via missing authorization

Published Apr 28, 2026 · Updated Apr 28, 2026

Missing authorization in Devolutions Server allows remote authenticated users to read documentation from unauthorized vaults. Vault documentation API endpoints return documentation for a requested vault without verifying that the caller is authorized for that vault. A valid low-privilege account and a crafted API request are required; the disclosed content is limited to vault documentation, with no reported write or service-interruption impact.
