Devolutions Server 2026.2.4.0 <= 2026.2.9.0 MFA Bypass (DEVO-2026-0023)

high Nessus Plugin ID 326247

Synopsis

The Devolutions Server instance installed on the remote host is affected by an authentication bypass vulnerability.

Description

The version of Devolutions Server installed on the remote host is 2026.2.4.0 prior or equal to 2026.2.9.0 and is, therefore, affected by an authentication bypass vulnerability:

 - Improper enforcement of a mandatory multi-factor authentication policy in Devolutions Server 2026.2.9.0 allows an attacker with valid user credentials to bypass the MFA Required policy and authenticate without completing multi-factor authentication. The problem occurs when DVLS encounters an invalid default MFA value.
 (CVE-2026-14536)

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

Solution

Upgrade to Devolutions Server version 2026.2.11.0 or later.
