CVE-2026-90969Network attack vectorHinoki check available

Password disclosure via unchecked entry listing parameters

Published Sep 15, 2026 · Updated Sep 15, 2026

Improper access control in Devolutions Server 2026.2.16 and earlier allows remote authenticated users to read stored cleartext passwords. The vault entry listing endpoint honors password-disclosure parameters without enforcing the caller's view-password permission. Any authenticated account that can list affected vault entries can expose their stored credentials despite lacking permission to view passwords.
