CVE-2026-3131Network attack vector

Credential disclosure via view-only connection requests

Published Feb 24, 2026 · Updated Feb 24, 2026

Improper access control in Devolutions Server 2025.3.14.0 and earlier allows remote authenticated users to read sensitive connection data. The /api/connections/{id} REST endpoints return sensitive connection details to accounts limited to view-only permission instead of enforcing the intended access boundary. A valid low-privilege account and a connection entry identifier are required; the documented consequence is disclosure, not modification or service interruption.
