Devolutions Server < 2025.3.18 / 2026.1.x < 2026.1.12 Multiple Vulnerabilities (DEVO-2026-0010)

high Nessus Plugin ID 304673

Synopsis

The Devolutions Server instance installed on the remote host is affected by multiple vulnerabilities.

Description

The version of Devolutions Server installed on the remote host is prior to 2025.3.18 or 2026.1.x prior to 2026.1.12. It is, therefore, affected by multiple vulnerabilities, including:

 - Improper authentication in the OAuth login functionality allows a remote attacker with valid credentials to bypass multi-factor authentication via a crafted login request. (CVE-2026-4828)

 - Improper authentication in the two-factor authentication (2FA) feature allows a remote attacker with valid credentials to bypass multifactor authentication and gain unauthorized access to the victim account via reuse of a partially authenticated session token. (CVE-2026-4924)

 - Improper authentication in the external OAuth authentication flow allows an authenticated user to authenticate as other users, including administrators, via reuse of a session code from an external authentication flow.
 (CVE-2026-4829)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Devolutions Server version 2025.3.18 / 2026.1.12 or later.
