The AssetsController->replaceFile() method has a targetFilename body parameter that is used unsanitized in a deleteFile() call before Assets::prepareAssetName() is applied on save. This allows an authenticated user with replaceFiles permission to delete arbitrary files within the same filesystem root by injecting ../ path traversal sequences into the filename.
This could allow an authenticated user with replaceFiles permission on one volume to delete files in other folders/volumes that share the same filesystem root.
This only affects local filesystems.
Users should update to Craft 4.17.5 or 5.9.11 to mitigate the issue.
