Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability has been found in Radarr 5.28.0.10274. The affected element is an unknown function of the file C:\ProgramData\Radarr\bin\Radarr.Console.exe of the component Service. Such manipulation leads to incorrect default permissions. The attack can only be performed from a local environment. The vendor was contacted early about this disclosure but did not respond in any way.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Radarr 5.28.0.10274 has incorrect default file permissions on the service executable (Radarr.Console.exe), allowing local users unauthorized access to modify or replace the binary, potentially leading to privilege escalation.

MitigationConfigure proper Windows ACLs on the Radarr service executable to restrict modification access to Administrators and SYSTEM only, then verify the service functions correctly.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Radarr version
    Open Windows PowerShell and run: Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*' | Where-Object {$_.DisplayName -like '*Radarr*'} | Select-Object DisplayName, DisplayVersion. Alternatively, check the version shown in the Radarr UI under System > Info.
    Affected if The installed version is 5.28.0.10274
  2. Locate Radarr.Console.exe
    Open PowerShell and run: Get-ChildItem -Path 'C:\Program Files' -Recurse -Filter 'Radarr.Console.exe' -ErrorAction SilentlyContinue | Select-Object FullName. Typical path is C:\Program Files\Radarr\Radarr.Console.exe.
    Affected if The file exists at the found location
  3. Check file permissions on Radarr.Console.exe
    Right-click Radarr.Console.exe in File Explorer, go to Properties > Security tab. Or run in PowerShell: Get-Acl 'C:\Program Files\Radarr\Radarr.Console.exe' | Select-Object -ExpandProperty Access | Where-Object {$_.FileSystemRights -match 'Write|Modify|FullControl' -and $_.AccessControlType -eq 'Allow' -and $_.IdentityReference -notmatch 'BUILTIN\Administrators|NT AUTHORITY\SYSTEM'
    Affected if Non-administrator users or groups (such as Users, Everyone, or authenticated users) have Write, Modify, or FullControl permissions on the executable
  4. Verify service runs under a privileged account
    Open Services (services.msc), find the Radarr service, right-click and select Properties. Check the 'Log On As' account. It should be a specific service account or SYSTEM, not a standard user account.
    Affected if The service runs under a standard user account rather than SYSTEM or a dedicated service account
  5. Confirm executable is replaceable by standard users
    As a non-administrative test (or via PowerShell with a test account), attempt to delete or rename the Radarr.Console.exe file. Or check inheritance: icacls 'C:\Program Files\Radarr\Radarr.Console.exe'
    Affected if Standard users can modify, delete, or replace the Radarr.Console.exe file

You are affected if Radarr version 5.28.0.10274 is installed AND standard (non-admin) users have Write, Modify, or FullControl permissions on the Radarr.Console.exe file, allowing them to replace the binary and escalate privileges.
