"The version of Devolutions Server installed on the remote host is prior to 2026.1.20. It is, therefore, affected by
multiple vulnerabilities, including:

  - Improper access control in the PAM account discovery feature in Devolutions Server 2026.1.19 and earlier allows an
    authenticated user without administrative privileges to delete network discovery scan configurations.
    (CVE-2026-9522)

  - Improper access control in the permission validation component in Devolutions Server 2026.1.19 and earlier allows
    an authenticated user with entry edit privileges to modify asset information without the required permission.
    (CVE-2026-9590)

  - Improper access control in the Synchronizer feature in Devolutions Server 2026.1.19 and earlier allows an
    authenticated user to use sealed credentials without triggering unseal prompts or administrator notifications via
    synchronizer entries. (CVE-2026-10615)

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