The fix

We hold no Microsoft remediation data for CVE-2026-62278, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

LubeLogger is a self-hosted, open-source, web-based vehicle maintenance and fuel mileage tracker. Prior to 1.6.8, authenticated non-administrative users could reach HandleTranslationFileUpload and influence the name passed from Controllers/FilesController.cs to RenameFile in Helper/FileHelper.cs. RenameFile constructed newFilePath with string replacement and moved the uploaded file without verifying the resolved absolute path remained under the web root or data directory. A crafted upload name could therefore move an uploaded file outside the intended storage directory, enabling unauthorized file placement or overwrite with the privileges of the application process. This issue is fixed in version 1.6.8.
