"The version of Devolutions UniGetUI installed on the remote host is 2026.2.0 or earlier. It is, therefore, affected
by an arbitrary code execution vulnerability:

  - Use of an incorrectly resolved name or reference in the pinget backend in Devolutions UniGetUI 2026.2.0 and
    earlier allows a WinGet community catalog contributor to cause an installed application to be correlated to an
    unrelated, attacker-controlled catalog package and to execute an attacker-controlled installer via a crafted
    catalog package whose normalized name is contained as a substring within the installed application name when a
    user applies the proposed update. (CVE-2026-10696)

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