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 checksWork through these to decide whether this CVE applies to you.
-
Identify if Stove client is installedLook for Onstove Stove in your installed programs (Windows Control Panel > Programs and Features, or macOS Applications folder, or check for Stove-related processes running in Task Manager/Activity MonitorAffected if The Stove client application is present on the system
-
Determine the installed Stove versionRight-click the Stove application icon, select Properties, and check the Details tab for version information; alternatively, check the program's About or Help menuAffected if The version displayed is between 0.0.4.10 and 0.0.4.71 inclusive
-
Verify the client can access the webCheck if Stove has any web-facing features, browser integration, or network listening capabilities by reviewing the application's permissions or network connections (use netstat or similar tool to see if Stove is bound to any ports)Affected if Stove accepts web input or has browser integration features enabled
-
Check for active Stove processesOpen Task Manager (Windows) or Activity Monitor (macOS) and look for the Stove client process runningAffected if The Stove process is currently running on the system
You are affected if the Onstove Stove client is installed and its version falls within the 0.0.4.10 to 0.0.4.71 range.
