CVE-2026-62278: LubeLogger: Path Traversal in HandleTranslationFileUpload Allows Authenticated Users to Write Files Outside Data Directory
Advisory generated from the CVE record, CISA, Exploit Observer and VEDAS: what it is, whether it is exploited, who is affected, and how to fix and detect it.

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.

Show the rules
# CVE-2026-62278 - LubeLogger < 1.6.8 path traversal in the translation file upload
# (FilesController.HandleTranslationFileUpload -> FileHelper.RenameFile). The uploaded file
# name is used to build the destination path without base-name reduction, so a name with
# ../ escapes the storage directory. Matches the authenticated multipart POST whose
