2026.2.12.0. It is, therefore, affected by multiple vulnerabilities, including:

  - Improper access control in the role membership management endpoint in Devolutions Server allows an authenticated
    non-administrative user holding the user-group membership management permission to escalate privileges to
    administrator via a crafted API request. (CVE-2026-17568)

  - Improper access control in the NetBox synchronizer in Devolutions Server allows an authenticated user with
    view-only permission on an entry to obtain a stored API token via the partial connection endpoint.
    (CVE-2026-17569)

  - Improper access control in the PAM password history endpoints in Devolutions Server allows an authenticated
    low-privileged user to disclose plaintext credential secrets via crafted API requests. (CVE-2026-17570)

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