## Affected

- n/a Sonarr: 4.0.15.2940

## Description

A vulnerability was found in Sonarr 4.0.15.2940. The impacted element is an unknown function of the file C:\ProgramData\Sonarr\bin\Sonarr.Console.exe of the component Service. Performing manipulation results in incorrect default permissions. The attack is only possible with local access. The vendor confirms this vulnerability but classifies it as a "low severity issue due to the default service user being used as it would either require someone to intentionally change the service to a highly privileged account or an attacker would need an admin level account". It is planned to fix this issue in the next major release v5.
