Server: Authentication Bypass by Primary Weakness

Published Updated By the CyberSecBulletin desk

CVE-2026-9047 is a high-severity authentication bypass by primary weakness vulnerability in Server from Devolutions, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected Server versions: 2026.1.6.0 through 2026.1.16.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.32% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Devolutions Server to 2026.1.19.0 or a later version.
  2. Read the advisory on devolutions.net for workarounds and exact fixed builds.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

Improper handling of factor key state in the multi-factor authentication management feature in Devolutions Server allows an attacker with knowledge of a user's password to bypass the user's multi-factor authentication after the user reconfigures their factors. This issue affects : * Devolutions Server 2026.1.6.0 through 2026.1.16.0

The underlying weakness: Authentication Bypass by Primary Weakness

The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.
