Medium (5.3) in filebrowser filebrowser. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in github.com/filebrowser/filebrowser/v2 2.63.1.
File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.1, the resourceGetHandler in http/resource.go returns full text file content without checking the Perm.Download permission flag. All three other content-serving endpoints (/api/raw, /api/preview, /api/subtitle) correctly verify this permission before serving content. A user with download: false can read any text file within their scope through two bypass paths. This vulnerability is fixed in 2.63.1.
