"The version of Adobe Lightroom Classic installed on the remote host is prior to 10.4. It is, therefore, 
affected by privilege escalation vulnerability. The vulnerability exists due to creation of temporary file in 
directory with incorrect permissions, which leads to security restrictions bypass and privilege escalation.

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