CVE-2026-100286 · Severity: medium · CVSS 6.5 · Published 2026-09-29

Devolutions Server is a centralized platform for managing remote connections and administrative credentials. An authenticated non-administrative user can exploit a missing authorization check in the data source settings API to retrieve integration secrets, such as database connection credentials or third-party service tokens. This allows an insider to access sensitive integration credentials they should not have permission to view.

## Technical details

Missing authorization checks in the data source settings API endpoint allow an authenticated non-administrative user to access integration secrets without proper role-based access control. The vulnerability requires an authenticated session but no special privileges; an attacker crafts an API request to bypass authorization logic and disclose credentials used for integrations. A patch is available in versions after 2026.3.5.0.
