"The version of Devolutions Server installed on the remote host is prior to 2026.1.21.0 or 2026.2.4.0 prior to
2026.2.5.0. It is, therefore, affected by multiple vulnerabilities, including:

  - Improper neutralization of special elements in the built-in PAM provider password rotation templates in
    Devolutions Server allows an authenticated user with write access to a vault to execute arbitrary commands on the
    systems managed by the affected PAM provider. (CVE-2026-10544)

  - Improper access control in the ticketing integration settings in Devolutions Server allows an authenticated
    low-privileged user to obtain cleartext credentials for configured ticketing integrations via a crafted API
    request. (CVE-2026-10786)

  - Missing authorization in the deleted user groups API in Devolutions Server allows an authenticated low-privileged
    user to enumerate metadata of deleted user groups via a crafted API request. (CVE-2026-10787)

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